SealLine ILBE Sack
Here's what other sites are saying:
When you have the U.S. Marines vying for your dry bags, as the ILBE is, you know they must be rugged. The ILBE dry pack from SealLine will hold up to every condition you can imagine offering unquestionable protection.
Improved Load Bearing Equipment - that's what SealLine had in mind when they designed the ILBE, an extremely durable dry bag crafted with bomber materials and a purge valve that has a 1000 lb crush rating. Used by the military in some of the roughest places on Earth, this bag protects your gear with tough nylon coated with High-Tenacity polyurethane and a Dry Seal dual-strip roll-down top.
