  • 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.
