Overview
This G4Free daypack packs down to 6.3 x 7.1 inches and weighs 0.75 lbs, built from water-repellent Taslan nylon for hiking, cycling, or as a spare bag inside a suitcase.
Its main selling point is how small it folds rather than how much it holds. At 20L it's sized for a day hike or a spare bag on a trip, not a multi-day pack, and the fabric is described as water-repellent rather than waterproof, which matters in a downpour.
- 20L capacity, folds to 6.3 x 7.1 inches
- 0.75 lb Taslan nylon build
- Zippered phone pocket, elastic snack pocket
- Adjustable mesh straps with chest strap
Who it's for
Fits hikers, cyclists, or travelers who want a foldable spare backpack for day trips. Not suited to multi-day backpacking, which needs more capacity and load support than a 20L packable bag offers.
Pros and cons
- Folds down to 6.3 x 7.1 inches for storage
- Weighs 0.75 lbs
- Zippered phone pocket and elastic snack pocket on the straps
- Adjustable, breathable mesh shoulder straps
- Water-repellent only, not waterproof
- 20L capacity limits it to day use, not multi-day trips
Performance notes
Taslan nylon gives the fabric abrasion resistance and light rain protection while keeping the pack under a pound. The bag folds into its own inner pocket down to 6.3 x 7.1 inches, small enough to sit inside a suitcase or larger backpack. Adjustable mesh shoulder straps and a movable chest strap are meant to keep it comfortable on the trail despite the light build.
