For maximum protection, the use of a waterproof hard case should be considered.

- Avoid contact with sharp objects or subjecting the sack to high abrasion, as this could compromise the waterproof fabric.
- Any roll-top dry sack must be closed properly to ensure water can’t get in. Begin by folding the Hypalon™ strip down first and be sure to have at least three rolls before closing the buckle.
