• Proper Use:
- 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
- Avoid contact with sharp objects or subjecting the sack to high abrasion, as this could compromise the waterproof fabric
- Ultra-Sil Dry Sacks should only be used to store sensitive electronic devices when used in conjunction with another, heavier-duty dry bag - the "double bag" method. For maximum protection of electronics the use of a waterproof hard case with a mechanical seal should be considered
