Vestibule

What is a tent vestibule?

A vestibule is the covered space between a tent's inner door and its fly, outside the sleeping area but under shelter. It's where boots, packs and wet gear live, and where you can cook in bad weather if you're careful.

Comfortable size: About 8 sq ft per person
Holds: Boots, pack, wet layers
Two doors: Worth a few oz in a 2P tent

A backpacking tent at dusk with the fly door rolled back, showing muddy boots and a pack stored on a groundsheet in the covered space between the fly and the glowing inner tent. — The vestibule: outside the inner, under the fly. Boots and a pack live here so the mud does not, and on a two-person tent two doors mean nobody climbs over anybody.

Where the vestibule comes from

A double-wall tent has an inner you sleep in and a fly over the top. Where the fly extends past the inner door, you get a covered patch of ground that isn't inside the tent. That's the vestibule, and it's the reason double-wall tents are still popular despite weighing more.

What it is for

It solves the problem of wet, filthy gear. Boots caked in mud, a soaked rain shell, a pack that's been sitting in drizzle: none of it belongs against your sleeping bag, and without a vestibule the choice is bringing it in or leaving it in the rain. Sizes get quoted in square feet, and anything around 8 sq ft per person is comfortable while much less becomes a boot cupboard.

Why two doors are worth it

Two doors and two vestibules cost a few ounces and are worth it in a two-person tent, because otherwise one person climbs over the other every time either of them goes out at night. On cooking: many people cook in a vestibule in bad weather, and stove makers uniformly advise against it. Fabric ignites, and carbon monoxide accumulates in enclosed spaces. If you do it, keep the fly rolled well back and never do it in a closed tent.

The common mistake

Cooking in one without ventilation

People do it and get away with it, and carbon monoxide is the reason some do not. If you cook under a fly at all, keep the door wide open, never run a stove in an enclosed vestibule, and never do it inside the inner.

Common questions

Can you cook in a tent vestibule?

Stove makers say no, and the risks are real: tent fabric burns fast and carbon monoxide builds up where air doesn't move. People do it in storms anyway, and the harm reduction is an open fly, a stable stove and never a closed tent.

How big should a vestibule be?

Around 8 sq ft per person takes a pack and boots with room to move. Under about 5 sq ft you're really just protecting footwear.

More in shelters

Freestanding tent

A freestanding tent holds its shape on its own poles without needing stakes to stand up. You can pitch it on rock or a wooden platform, pick it up to move it, and shake it out, none of which a staked shelter allows.

Trekking-pole tent

A trekking-pole tent uses the poles you're already carrying as its structure, so it ships without a pole set. That removes a pound or more from the pack, and requires stakes and taut guylines to stand up at all.

Footprint

A footprint is a shaped sheet of fabric that goes under a tent to protect the floor from abrasion and punctures. It's almost always sold separately, and a piece of polycryo or Tyvek does the same job for a fraction of the weight and cost.

Trail weight

Trail weight, sometimes called minimum weight, counts only a tent's essential parts: inner, fly and poles. Packed weight counts everything in the box, including stakes, guylines, stuff sacks and instructions. The gap is usually several ounces.

Bathtub floor

A bathtub floor is a tent floor whose waterproof fabric curves up the sides several inches before meeting the walls, so the seams sit above ground level. Water running under the tent has no seam to get through.

Gathered-end hammock

A gathered-end hammock is a flat rectangle of ripstop nylon bunched to a single point at each end and hung from two trees. It is the standard camping design, and it only lies flat if you sleep diagonally across it rather than down the middle.

Structural ridgeline

A structural ridgeline is a fixed length of cord tied between a hammock's two gathered ends. Because it cannot stretch, it holds the hammock at one repeatable amount of sag no matter how far apart the trees are, so the bed feels the same at every campsite.

Double-wall tent

A double-wall tent is built as two separate layers: an inner body, usually largely mesh, and a waterproof rainfly over it. Condensation collects on the underside of the fly instead of on the surface you and your bag are touching.
