What to Compare Before Buying
- Capacity: This version is 20L. Compare that with the amount you want to store in one sack.
- Format: It is a dry sack rather than a general storage bag, so check that this style suits your packing system.
- Closure: The roll-top closure is a key part of the design, so make sure that is the style you want.
- Organisation: It is part of a coordinated packing system, so consider whether you want an accessory that fits into a broader packing setup.
