Overview
A 20-liter packable daypack that folds down into its own built-in pouch, made from water-resistant polyamide with three zippered compartments for day trips, hiking or use as a carry-on personal item.
The appeal here is that it disappears when not needed: the whole 20L pack collapses into a pouch about the size of a sandwich, so it can ride inside a suitcase on the way out and hold souvenirs on the way home. Three separate zippered sections, plus mesh side pockets for bottles, keep it from being just one undivided sack. It's built as a spare or day bag, not a structured trekking pack for heavy loads.
- 20L unfolds to 16.5 x 11.8 x 6.3 in
- Three zippered compartments
- Water-resistant, tear-resistant polyamide
- Adjustable S-shape mesh shoulder strap
Who it's for
Travelers who want a spare bag that packs flat inside a suitcase for the trip home, and day hikers who need a light pack rather than a multi-day frame pack.
Pros and cons
- Folds into its own pouch when empty
- Mesh side pockets hold water bottles
- Sized to work as an airline personal item
- Reinforced stitching at stress points
- 20L capacity limits it to day trips, not multi-day gear
- Lightweight build trades off some structure
Performance notes
The main compartment is sized to hold a tablet and clothing, with an inner zippered pocket for cash and cards, two mesh side pockets for water bottles, and reinforced stitching at 14 points where straps meet the body to resist tearing under load. It folds into its own pouch to about the size of a sandwich when empty, and the S-shaped mesh shoulder straps adjust for fit.
