Begin by folding the Hypalon(TM) 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.Like all manufacturers of roll-top, fabric dry sacks, Sea to Summit recommends that sensitive electronic devices be ‘double bagged’ (i.e. putting electronics inside one dry sack then placing this inside a second dry sack). For maximum protection, the use of a waterproof hard case should be considered.Not intended for situations where dry sack will be submerged under water.
