Some Sea to Summit dry bags / dry sacks come with an advisory label sewn in to the upper seam. This label details the limitations of dry bags for storage of sensitive items such as electronics in potential submersion environments. Once you have read the label, carefully remove it from the dry bag.
Before each use, check your dry bag to see if there is any damage to the exterior fabric or the interior coating/flim. If there is, do not use the dry bag.
Once you have packed your gear inside the dry bag, here's how to seal it correctly:
- squeeze any excess air out of the bag before you roll down the roll-top closure
- fold the closure over onto the black hypalon seal strip - keep the fabric of the dry bag nice and taut as you do this
- fold the closure over at leat two more times in the same direction
- click the side-release buckle together
As mentnioned above, there are limitations on transporting electronic devices in very wet / potential submersion environments. Here are two options:
- 'Double bag' the electronics. Place the phones, keys wallets etc in one dry bag, roll the closure down tightly three times and click the side-release buckle. Then place this dry bag in a (slightly larger) dry sack. If sealed correctly, this would allow you to submerge the double-bag combination
- Buy a hard case with an 'O' Ring seal - there are products available from brands such as Pelican Case and Otter Box. Care should be taken to ensure that fine grain sand does not interfere with the 'O' Ring seal.
