The best daypacks

Lunch, a flask, a waterproof and the map: the rucksacks for a good day out walking.

Top 5 · Updated 28 September 2026

A daypack is the rucksack for a day's walk: big enough for water, lunch, a waterproof and a spare layer, without the weight of a big trekking pack. Around 20 litres suits most day walks; 30–40 litres gives room for family kit or a weekend away.

Look for a chest strap to stop it swinging, side pockets you can reach for a bottle, and a breathable back. Packable ones fold into their own pocket for holidays.

What matters

  • 15–20L for a day, 30–40L for more.
  • A chest strap and padded straps.
  • Water-resistant fabric, or a rain cover.
  • Side pockets for bottles.

SKYSPER 20L Hiking Daypack

£30–£50 Price range

9.3/10Picked Rating

The right size for a day on the hills: room for a waterproof, lunch, a flask and a spare layer, with a ventilated back, reflective trim, trekking-pole loops and a hidden anti-theft pocket.

What owners say: Owners find it excellent quality with lots of zipped pockets, comfortable and light, and big enough for a day walk.

A closer look: Pack the heavy things (water, flask) closest to your back and it carries far better. Water-resistant isn't waterproof: line it with a bin bag on wet days.

  • 20 litres
  • 600D polyester and ripstop nylon, water-resistant
  • Breathable grooved back panel
  • Trekking-pole loops, chest strap with whistle
  • About 500g

MOUNTAINTOP 40L Hiking Backpack

£30–£50 Price range

9.1/10Picked Rating

Big enough for a weekend: a 40-litre main section, two front pockets, side mesh pockets and a hip-belt pocket, with YKK zips and compression straps for a sleeping mat.

What owners say: Owners find it good quality with plenty of storage and handy side pockets for bottles, comfortable and good value.

A closer look: Tighten the hip belt first, then the shoulder straps: the hips should carry most of the weight. The D-rings on the front take a mug or a torch.

  • 40 litres
  • 420D nylon and polyester
  • YKK zips
  • Hip belt with pocket, compression straps
  • 950g

Waterfly 15L Packable Daypack

£20–£30 Price range

9.1/10Picked Rating

Folds into its own pocket, about the size of a paperback, so it slips into a suitcase for city days and beach walks on holiday. Only 300g, with a chest-strap whistle and pole loops.

What owners say: Owners find it excellent quality, light and ideal for day trips and travel, and like that it folds into a small pouch.

A closer look: Keep it folded in a suitcase or coat pocket for the days you buy more than you can carry. The light padding suits loads of a few kilos, not a full day's gear.

  • 15 litres
  • Nylon ripstop, water-resistant finish
  • Folds into its own pocket (20 × 17 × 5.5cm)
  • About 300g
  • Metal zips, reflective trim

IGOLUMON 40L Lightweight Foldable Backpack

£20–£30 Price range

8.9/10Picked Rating

Forty litres that weighs just 550g and folds away, with a separate wet pocket for swimming kit or muddy waterproofs and straps underneath for a mat.

What owners say: Owners find it a brilliant hiking bag with lots of pockets and good value, and like that it packs in a suitcase.

Heads up: It's water-repellent rather than waterproof, so put a phone or spare clothes in a dry bag on wet days.

A closer look: The wet pocket is the clever bit: swimming kit or muddy boots go in without soaking everything else. It folds into the suitcase for holidays.

  • 40 litres
  • Tear-resistant nylon, water-repellent
  • Separate wet pocket
  • 550g, folds away
  • Pole straps, bottom straps for a mat

Best for: Swims and beach days

POWER KING 30L Hiking Backpack with Rain Cover

£20–£30 Price range

8.8/10Picked Rating

A rain cover tucked into the bottom pocket, a padded sleeve for a 15.6in laptop, and two main compartments: one bag for walks at the weekend and the commute during the week.

What owners say: Owners find it well made and comfortable, with plenty of pockets and space, and think it's good value.

A closer look: Pull the rain cover over at the first drops; it's quicker than stopping for a coat. The laptop sleeve makes it a good college or commuting bag too.

  • 30 litres
  • Rain cover included
  • Padded 15.6in laptop sleeve
