36L Outdoor Hiking Backpack: The Complete Guide to Choosing the Right Day Pack

2 min read

A bad backpack costs you more than just comfort. It costs you the hike — early turnarounds because your shoulders are burning, gear you left at home because there was no room, frustration with straps that slip every hundred metres. The 10L Lightweight Outdoor Sport Backpack ($24.51) — compact daypack for shorter loops or as a satellite bag when the 36L is your base

  • Adventurer Rucksack ($54.95) — canvas construction for a more rugged aesthetic, slightly different carry style
  • Classic Euro Travel Organizer Bag ($36.95) — pairs well as a personal item when the 36L goes in the overhead
  • Frequently asked questions

    Is 36L enough for an overnight hike?
    It depends on how you pack. Ultralight hikers can do a two-day trip in 36L with a compact sleeping setup. For most people with standard gear, 36L comfortably handles a full day and stretches to a one-night trip with careful packing. For multi-day trips, a 50L to 65L pack is more comfortable.

    Does it fit a hydration bladder?
    The main compartment accommodates a standard 2L to 3L hydration bladder. Check whether the specific bladder you use has a hose port that works with the bag's construction — most standard bladders will fit.

    Will it fit as carry-on luggage?
    A packed 36L bag typically fits within most airline carry-on size limits, but check your specific airline's dimensions before traveling. It should slide into most overhead bins comfortably.

    How do I adjust the straps properly?
    Load the pack with your typical carry weight before adjusting. Loosen all straps, put the bag on, then tighten the shoulder straps until the bag sits comfortably against your back. Clip the chest strap at a level that feels natural across your ribcage — not too high, not across your throat. Tighten load lifter straps (if present) until the top of the bag angles slightly toward you.

    Is it waterproof?
    The fabric is water-resistant but not fully waterproof. In light rain it will perform well; in heavy sustained rain, use a rain cover or pack your critical items (electronics, dry clothes) in a dry bag inside the main compartment.

    What is the weight of the empty bag?
    The empty bag is lightweight enough that it does not meaningfully add to your carry weight — the design prioritises durability without adding unnecessary frame weight.

    Can kids use it?
    The strap system adjusts to fit a range of torso sizes, so older kids and teens can use it comfortably. For younger children, a smaller dedicated kids' pack is usually a better fit.
