Overview
A drawstring and zipper close this small foldable backpack, which carries a shoulder strap, a side water bottle pocket and a keys pocket. Nylon lining and a lightweight soft shell make it packable.
Tiny weight and a folding design make it a spare bag for trips. Material listings disagree, with nylon in one field and faux leather in another, and the volume is small for a full hiking day.
Who it's for
A traveler or gym-goer who wants a bag that folds into a pocket. Hikers carrying water, layers and food for a long day should choose a larger pack with a frame.
Pros and cons
- Folds into a small bundle
- Bottle pocket on the side
- Water resistant nylon
- Material fields disagree
- Wipe clean care only
Performance notes
The main compartment closes in two stages. Thin fabric means the bag takes the shape of its load, so sharp items poke through. Padding and a hip belt are not listed, which limits carry comfort on long walks.
