Quick answer: for most day hikes, a 20–30 litre pack with a padded hip belt, a ventilated back panel, a hydration sleeve and side bottle pockets is ideal. Under $100 you can get excellent packs from Osprey, REI Co-op, Deuter and Gregory. Try packs on with weight inside: fit matters more than features.

Features that matter
- Torso fit: measure from the bony bump at the base of your neck (C7) to the top of your hip bones; choose a pack size that matches.
- Hip belt: even a light belt moves weight onto your hips on longer hikes.
- Back ventilation: mesh or channelled back panels reduce sweaty backs.
- Hydration sleeve: for a water bladder; side pockets for bottles you can reach without stopping.
- Rain protection: few daypacks are waterproof; carry a rain cover or use a liner bag.
- Pockets: a stretch front pocket for layers and hip-belt pockets for snacks and phone.
- Trekking pole attachment for scrambles and road sections.

Frequently asked questions
Is 20 litres enough for a day hike?
Usually, yes, for warm-weather hikes. Choose 25–30 L if you carry extra layers, food for others or winter gear.
Do I need a hip belt on a daypack?
For loads over about 5 kg (11 lb), yes; it takes pressure off your shoulders.
How should a daypack fit?
The hip belt sits on your hip bones, shoulder straps wrap without gaps, and the pack doesn’t sway when you walk.
