How to Choose a Hiking Backpack in 2026: Capacity, Fit and Fabric
Torso length matters more than litres, and the fit is free. A practical guide to buying a pack that does not ruin the walk.
In this guide · 6 sections
Most people buy a hiking pack by capacity and regret it by fit. Litres tell you what you can carry; torso length tells you whether carrying it will be miserable. Get the second right and a 65-litre pack feels lighter than a badly fitted 45.
Capacity by trip length
| Trip | Capacity | Typical loaded weight |
|---|---|---|
| Day walk | 20–30L | 5–8kg |
| Overnight | 35–50L | 9–13kg |
| 2–4 nights | 50–65L | 12–18kg |
| 5+ nights or winter | 65–80L | 16–25kg |
Measure your torso, not your height
Torso length is the distance from your C7 vertebra — the bump at the base of your neck when you tip your head forward — to the top of your iliac crest, the shelf of your hip bones. Two people of the same height can differ by 8cm.
- Tip your head forward and find the bony bump at the base of your neck
- Put your hands on your hips, thumbs pointing back, and find the line between your thumbs
- Have someone measure between those points along your spine
- Match against the manufacturer's chart — 43–48cm is typically medium
The hipbelt carries the weight
Around 80% of the load should sit on your hips, not your shoulders. The hipbelt should wrap the iliac crest, not the waist above it. Load the pack with about 12kg before fitting — an empty pack tells you nothing about how it will carry.
The best all-rounder
For heavier loads
Fabric and weight
Denier ratings describe fibre thickness: 100D is light and less durable, 400D+ is heavy-duty. Most quality packs mix them, using tough fabric on the base and lighter fabric up top. Ultralight packs using Dyneema resist abrasion well but cost substantially more.
Prices were correct at the time of writing and are re-checked automatically, but retailers change them often — confirm on the retailer's page before buying.
What size backpack for a week of hiking?
65–75 litres for a week carrying your own shelter and food. Less if staying in huts or resupplying along the way.
Are expensive packs worth it?
Up to a point. $81 to $250 buys a real suspension system and much better comfort. Beyond $400 you are mostly buying weight savings.
Men's or women's pack?
Women's packs have shorter torso ranges, differently angled shoulder straps and a hipbelt shaped for a wider iliac crest. Buy whichever fits your measurements.
