The verdict

Is the Osprey Daylite Plus 20 worth it?

Yes, for most day hikers. The Daylite Plus 20 holds water, food, a warm layer and a rain shell in a pack that weighs about 1.3 pounds, with stretch side pockets and a front stash pocket for wet gear. Its thin webbing hipbelt and foam back limit it to light loads, roughly ten pounds or less.

That is why it tops our day hiking pack ranking. Twenty liters is what a typical day hike actually needs, the pockets are where your hands expect them, and it has by far the largest pool of Amazon buyer ratings in the guide, with a high average.

The trade-offs show up on long, hot or heavy days. The foam back sits flat against you and gets sweaty on summer climbs, and the webbing strap does little to move weight off your shoulders. For a full day with lots of water, a pack with a padded hipbelt carries better.

Buy it if

  • A first day pack for half-day and full-day hikes
  • Hikers who want one bag for the trail and the commute
  • Travel as a carry-on or a daypack on a bigger trip
  • Loads under about ten pounds

Skip it if

  • You carry heavy loads or lots of water on long days
  • You hike mostly in summer heat and want a ventilated back
  • You want a built-in rain cover

What's good

  • Twenty liters fits a full day's essentials without extra bulk
  • Light enough that you barely notice it on easy trails
  • Panel-loading zip opens wide, so gear is easy to find
  • Works as a daily bag as well as a hiking pack

What to know

  • Webbing hipbelt does little to take weight off your shoulders
  • Foam back panel gets warm against your back in hot weather
  • No rain cover included

What fits in the Osprey Daylite Plus 20?

Enough for a typical day hike: two liters of water, lunch and snacks, a warm layer, a rain shell, a small first aid kit and a headlamp. The front shove-it pocket takes a damp jacket so it stays away from dry gear.

The internal sleeve fits a hydration reservoir or a tablet, and some buyers report fitting a laptop in it. A big winter jacket or a bear canister will crowd it, so step up in size for those trips.

Is the Daylite Plus 20 comfortable for long hikes?

With a light load, yes. The spacer mesh straps are soft and the pack sits close and stable. Past about ten pounds, more of the weight lands on your shoulders because the waist strap is plain webbing, so for long days with lots of water a pack with a padded hipbelt is more comfortable.

Questions

Osprey Daylite Plus 20 FAQ

Is 20 liters enough for a day hike?

For most day hikes, yes. It holds water, food, layers and the basic safety kit. Choose something closer to 25 or 30 liters for winter hikes or if you carry gear for a child too.

Does the Osprey Daylite Plus have a hip belt?

It has a removable webbing waist strap rather than a padded hipbelt. It keeps the pack from swinging, but it does not carry much of the weight.

Can the Daylite Plus attach to a bigger Osprey pack?

Yes. Osprey designs the Daylite range to clip onto several of its larger packs, so it can ride along on a trip and come off for day hikes. Check Osprey's compatibility list for your pack.

Can the Daylite Plus 20 be a carry-on?

At about 18 by 11 by 8 inches, it fits most airlines' personal item or carry-on limits. Check your airline's size rules before you fly.
