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.
