How to Choose
How to Choose Gear Repair and Waterproofing Products
Most hiking gear doesn't die. It wears out a little at a time. A rain jacket starts to feel wet on the shoulders, boots start darkening at the toe after an hour in wet grass, or a tent seam drips onto the foot of your sleeping bag. Each of those has a fix that costs a fraction of a new jacket, boot or tent.
This page is those fixes: wash-ins and sprays that bring back a jacket's water repellency, wax and treatments for boots, peel-and-stick tape, seam sealers, a tent pole splint and a zipper kit. It's arranged by the gear each one fixes, rain jacket first, then boots, then tent and hardware.
The twelve picks come from Nikwax, Grangers and Gear Aid, the three names outdoor shops stock for this job. They're ranked on how much of a common failure each one fixes, from each maker's published instructions and what Amazon buyers report. My dad and I haven't used every one of them on our own gear, and I won't pretend we have.
Quick Picks
Top Three at a Glance
Short on time? Start with these top-rated gear repair & waterproofing picks.
If you buy one thing on this page, make it this. It pairs Tech Wash, a cleaner for waterproof clothing, with TX.Direct Wash-In, which restores the water repellency. Together they fix the most common reason a good rain jacket starts to feel wet inside.It all happens in a washing machine, so there's no skill involved. Clean the machine's detergent drawer first, wash with Tech Wash, then run TX.Direct in a second cycle. Each bottle covers a few washes.
Tenacious Tape is the patch hikers carry, and the clear roll is the most versatile version. You cut a patch to size, round the corners and press it on. It sticks to most nylon and polyester gear, from a puffy to a tent fly, and Gear Aid says it holds through washing once it has set.It's a field repair that often ends up being the permanent one. A short length folded around a pencil or trekking pole weighs next to nothing and can save a trip.
Seam Grip WP is a urethane sealer and glue that cures into a flexible, waterproof layer. It's the fix for a tent or rain fly seam that drips, and for gluing down a patch or a tear that tape alone won't hold. Gear Aid's listing quotes a seam-coverage figure of about 12 feet for the 1 oz tube, so expect it to cover a few seams rather than a whole tent.Give it time. It needs to cure overnight before you pack the gear away, so it's a job for home rather than camp. And it's for polyurethane-coated fabric only: on silnylon, use Seam Grip SIL.

Why It Stands Out
Covers both steps: clean, then reproof
Machine-wash application, no technique to learn
Water-based, per Nikwax
Pros
Low-cost way to bring back a tired shell
Works on jackets and rain pants alike
Enough for several treatments
Cons
Not the right choice for jackets with a wicking liner
Two full wash cycles take time
Best Situations
End-of-season care for a rain jacketA shell that soaks through on the shouldersRain pants that wet out at the knees
Quick verdict: Tenacious Tape is the patch hikers carry, and the clear roll is the most versatile version. You cut a patch to size, round the corners and press it on. It sticks to most nylon and polyester gear, from a puffy to a tent fly, and Gear Aid says it holds through washing once it has set.
It's a field repair that often ends up being the permanent one. A short length folded around a pencil or trekking pole weighs next to nothing and can save a trip.
Why It Stands Out
Peel-and-stick, no glue or cure time
Clear, so it hides on any color
Cut to any shape from one roll
Pros
Works in the field with no tools beyond scissors
Light enough to carry on every hike
Fixes puffies, shells, packs and tents
Cons
Needs clean, dry fabric to stick well
Not the right fix for a leaking seam
Best Situations
A branch rips a down jacketAn ember burns a hole in a rain shellA small tear in a tent fly or mesh
Quick verdict: Seam Grip WP is a urethane sealer and glue that cures into a flexible, waterproof layer. It's the fix for a tent or rain fly seam that drips, and for gluing down a patch or a tear that tape alone won't hold. Gear Aid's listing quotes a seam-coverage figure of about 12 feet for the 1 oz tube, so expect it to cover a few seams rather than a whole tent.
Give it time. It needs to cure overnight before you pack the gear away, so it's a job for home rather than camp. And it's for polyurethane-coated fabric only: on silnylon, use Seam Grip SIL.
Why It Stands Out
Seals seams and repairs tears in one tube
Stays flexible once cured
Works on nylon, polyester, canvas and vinyl
Pros
Permanent repair
One tube handles a few problem seams
Also fixes sleeping pad and dry bag leaks
Cons
Long cure time
Won't bond to silicone-treated fabric
Best Situations
A tent fly seam that drips in heavy rainPeeling factory seam tapeA torn tarp or dry bag
Quick verdict: This is the spray version of the wash-in in the duo-pack, and it exists for one reason. Nikwax's listing points to it for garments with a wicking inner lining, since you treat only the outside and the liner can keep pulling sweat away from your skin.
It also lets you spot-treat the parts that wear first: shoulders where pack straps rub, cuffs and the hood. Spray it on a clean, wet jacket and let it dry.
Why It Stands Out
Treats the outer fabric only
Lets you target high-wear areas
No washing machine needed
Pros
Right for lined jackets
Good for spot treatment
Pairs with Tech Wash
Cons
Slower than a wash-in for a whole jacket
Harder to get even coverage
Best Situations
A lined rain jacketPack straps wearing off the shoulders' finishA quick touch-up before a wet trip
Quick verdict: Grangers is the long-standing alternative to Nikwax, and Repel Plus is its spray-on reproofer for technical shells, with the listing naming Gore-Tex and eVent. You spray it on a clean, damp garment and let it dry.
The 500 ml bottle is larger than Nikwax's 300 ml spray, which suits a household with several shells to treat. Grangers also makes its own cleaner, Performance Wash, if you want to stay with one brand.
Why It Stands Out
Made for Gore-Tex, eVent and similar shells
Bigger bottle for multiple jackets
Spray lets you treat the outside only
Pros
Treats several jackets per bottle
Simple spray-and-dry application
Strong Amazon rating
Cons
Fewer reviews than the Nikwax sprays
Still needs a clean jacket first
Best Situations
Reproofing a family's rain gear at onceSki shells and rain shellsA brand alternative to Nikwax
Quick verdict: Most hiking boots and shoes today are a mix of fabric and leather, often with a membrane inside, and this is the treatment made for that mix. Nikwax says it's water-based and keeps the upper breathable, which matters on a Gore-Tex boot.
The sponge applicator makes it easy: clean the boots, apply it while they're still wet, wipe off the excess and let them dry naturally. Nikwax sells a footwear cleaning gel to go with it.
Why It Stands Out
Made for mixed fabric and leather uppers
Keeps membrane boots breathable
Built-in sponge applicator
Pros
Right for most modern hiking boots and shoes
No waiting for boots to dry first
Also works on trail shoes
Cons
Less conditioning for full-leather boots than a wax
Lower rating than the wax
Best Situations
Fabric boots that soak through at the toeMembrane boots that feel clammyEnd-of-season boot care
Quick verdict: For a smooth leather boot, a wax does two jobs: it waterproofs the leather and keeps it from drying out and cracking. Nikwax's version is water-based and comes in a tube with an applicator, and Nikwax says it's safe on Gore-Tex-lined boots.
It's made for smooth leather only. Nubuck and suede need a different product, and on a boot with big fabric panels the Fabric & Leather Proof above is the better choice.
Why It Stands Out
Waterproofs and conditions in one step
Safe for membrane-lined boots, per Nikwax
Tube with a built-in applicator
Pros
Cheap enough to keep a tube at home
Strong rating from a large base of buyers
Leaves leather supple
Cons
Smooth leather only
Can darken lighter leather
Best Situations
Full-leather backpacking bootsLeather that looks pale and dryBefore a wet or snowy trip
Quick verdict: When a boot's sole starts peeling away at the toe, that's the end for a lot of boots, and it doesn't need to be. Aquaseal SR is a urethane adhesive that cures to a tough, flexible rubber. Gear Aid sells it for re-gluing soles, sealing holes and rebuilding worn heels.
Clean the surfaces, apply it, clamp or tape the sole shut and give it time to cure. It's a home repair, not a trail one, but it can add seasons to a boot you like.
Why It Stands Out
Cures to flexible, waterproof rubber
Re-glues soles and fills holes
Rebuilds worn heels
Pros
Saves a boot that's otherwise fine
Small 1 oz tube stores easily
Works on shoes and sandals too
Cons
Needs clamping and a long cure
Messy if you overapply it
Best Situations
A sole peeling at the toeA worn heel on a favorite pairA small hole in a rubber rand
Quick verdict: A tent fly loses its water repellency the same way a jacket does, and it also takes a beating from the sun. SolarProof restores the repellency and adds UV protection, according to Nikwax, for tents, packs and covers.
Pitch the tent, wet the fly, spray it evenly and wipe off the excess. It's the right buy for an older tent whose fly now soaks through instead of beading.
Why It Stands Out
Restores water repellency on tents
Adds UV protection to the fabric
Water-based spray
Pros
Extends the life of an older tent
Also works on packs and covers
Strong rating
Cons
A large fly takes most of a bottle
Not a fix for leaking seams
Best Situations
A tent fly that no longer beadsA tent pitched often in high sunA pack cover that wets out
Quick verdict: Many ultralight tents and tarps use silicone-coated fabric, and a lot of them ship with seams you have to seal yourself. Seam Grip SIL is the sealer for that. Gear Aid's listing says it is for silicone-treated fabric, and quotes coverage of up to about 24 feet of seams per tube.
Pitch the tent taut, brush it thinly along the seams, and leave it up until it cures. Gear Aid's listing ties it to the older SilNet name.
Why It Stands Out
Made for silicone-coated fabric
Sized for a small tent's seams, per Gear Aid
Brush applicator in the box
Pros
The right chemistry for silnylon
Thin enough to flow into seams
Strong rating
Cons
Useless on polyurethane-coated fabric
Needs a pitched tent and dry weather
Best Situations
A new ultralight tent with unsealed seamsA silnylon tarpRe-sealing an older silnylon fly
Quick verdict: Without a splint, a cracked pole at camp means a sagging tent for the rest of the trip. A splint is a short aluminum sleeve that slides over the break and gets taped in place, and it holds the pole together until you get home.
This is the 5/8 inch version. Gear Aid also sells a 1/2 inch one, so measure your pole before you buy. Many tents ship with a splint in the stuff sack already.
Why It Stands Out
Bridges a broken or bent pole section
Weighs next to nothing
Only needs tape to fit
Pros
Saves a trip for very little weight
Small enough to live in a repair kit
Very cheap
Cons
Size has to match your pole
Fewer Amazon reviews than the rest of this page
Best Situations
A pole that cracks in a windstormA bent section after a fallA spare for a tent that didn't come with one
Quick verdict: Zippers fail more often than fabric, and most of the time the slider has worn out, not the teeth. This kit has replacement sliders in several sizes plus top stops, needles and thread, so you can swap a worn slider instead of replacing the whole zipper.
It's the most hands-on fix on this page. You'll need pliers and a little patience, and you have to match the slider size to your zipper. It also has the lowest rating here, so read the size guide before you start.
Why It Stands Out
Covers the most common zipper failure
Several slider sizes in one kit
Includes stops, needles and thread
Pros
Far cheaper than a zipper replacement
Fixes tents, sleeping bags and packs
Enough parts for several repairs
Cons
Lowest rating on this page
Slider sizing takes some figuring out
Best Situations
A tent door that splits behind the sliderA sleeping bag zipper that won't closeA pack pocket with a worn slider
Most rain jackets that feel like they leak are wetting out. The DWR finish on the outside has worn off, the face fabric soaks up water, and the membrane can't breathe through a wet layer, so your own sweat condenses inside. It feels exactly like a leak, but the membrane is usually fine.
The test is simple: sprinkle water on the shoulders. If it beads and rolls off, the finish is working. If it spreads into a dark patch, the DWR needs reviving. A real leak shows up as one wet spot inside in the same place every time, usually a seam or a hole, and that needs a patch or sealer instead.
That sprinkle is a home version of the lab spray test fabric makers use to grade water repellency, AATCC 22 in the US and ISO 4920 in Europe. Both spray water on a taut sample and score how much of it wets the surface.
Should you clean gear before you reproof it?
Yes, and it fixes more than people expect. Dirt, sunscreen and body oils mask the water-repellent finish, and Nikwax says ordinary detergent leaves residues that attract water. A wash with a technical cleaner can sometimes bring the beading back on its own.
Gore-Tex's own care guidance also says a warm tumble dry can reactivate the finish, so try a clean wash and a dry before you buy a reproofer. If the water still soaks in after that, then the finish is worn out and needs replacing.
Should you use a wash-in or a spray-on reproofer?
A wash-in treats the whole garment evenly in a washing machine, and it's the easy choice for a plain shell. A spray goes only where you aim it, which is what you want on a jacket with a wicking inner lining, a pack, or just the shoulders and cuffs that wear first.
Nikwax's listing points to its spray-on version for garments with a wicking lining, so only the outside gets treated and the liner can keep pulling sweat away from your skin. For boots and tents, the treatment is always applied by hand.
Which seam sealer should you use on a tent?
Seam sealers aren't interchangeable. Seam Grip WP is a urethane that bonds to polyurethane-coated nylon and polyester, which is most rain gear and most tents. Silicone-coated fabric, sold as silnylon or silpoly, rejects it, and that's what Seam Grip SIL is for.
Check the tent maker's care page before you buy. It usually names the coating and the sealer it recommends. Using the wrong one is the most common seam-sealing mistake, and it looks fine until the first storm peels it off.
If your jacket soaks through
Clean, then reproof
Wash it in Tech Wash and follow with TX.Direct in the same duo-pack. That's two machine cycles and a dry, and it covers the most common reason a good shell starts to feel wet inside.
If there's a hole or a rip
Peel-and-stick patch
Cut a piece of Tenacious Tape that overlaps the damage on every side, round the corners so they don't lift, and press it down hard on clean, dry fabric. It works on a puffy, a rain shell or a tent fly, and it can go on in the field.
If a seam drips
Urethane or silicone
Brush Seam Grip WP along a coated nylon or polyester seam and let it cure overnight. If the tent is silnylon, use Seam Grip SIL instead, because a urethane sealer won't hold on silicone.

When water stops beading on it, not on a schedule. For a jacket worn every week through a wet season that might be once or twice a year. Wash it first and give it a warm tumble dry if the care label allows, since Gore-Tex says that can reactivate the finish, and reproof only if it doesn't.
It's better not to. Nikwax says conventional detergents leave water-attracting residues behind, which work against the water-repellent finish you're trying to keep. Use a technical cleaner like Tech Wash, or follow your jacket maker's care label, and skip fabric softener.
Yes, it's one of the most common uses for it. Push any escaping down back inside, clean the area, cut a patch with rounded corners that overlaps the hole, and press it on firmly. The clear version is the least noticeable on a colored jacket. Warm the patch with your hand for a minute after pressing it down, and give it time before you stuff the jacket back into a pack.
Pitch the tent taut on a dry, warm day so the seams are under tension. Clean the seam, brush a thin layer of sealer along it from the inside, and leave the tent pitched until it cures. Use Seam Grip WP on polyurethane-coated fabric and Seam Grip SIL on silnylon. Many tents come with factory-taped seams. Those only need sealer where the tape has started to peel.
Clean off the mud first, then apply a treatment made for your boot's material. Smooth leather takes a wax like Nikwax Waterproofing Wax for Leather. Boots that mix leather and fabric panels need a treatment made for both, such as Nikwax Fabric & Leather Proof, since a heavy wax can clog the fabric. Nikwax applies its boot treatments to clean, wet boots, so you don't need to wait for them to dry first.
Usually, yes. Slide a pole splint over the broken section so it bridges the break, center it, and tape both ends with duct tape or Tenacious Tape. It will hold the tent up for the rest of the trip. Measure your pole's diameter before you buy, since splints come in different sizes.
Usually because the slider has worn and spread, not because the teeth are damaged. Gently squeezing the slider with pliers is a common trail fix. When that stops working, replacing the slider with one from a repair kit is the long-term fix, and it's a lot cheaper than replacing the zipper.
