USMC Seal Line 56L 3 Day Pack Waterproof Liner

CONDITION: NEW

The SealLine ILBE Waterproof Liner was designed for the US Marine Corps to fit perfectly line the inside of the ILBE 3 day Pack (but it works easily with many other similar capacity packs) providing waterproofing protection to the pack's contents.  The liner is made from 210D oxford nylon with a high-tenacity polyurethane coating for added strength.  A waterproof seal is made with SealLine's exclusive DrySeal roll-down closure that buckles into place. 

A manual air purge valve can be opened as the bag is being sealed to let out any excessive air, and then closed to prevent additional air from returning into the bag after being sealed.  This is a 56 Liter dry bag that is about 24" tall with a 13" diameter.  It could be used as a standalone dry bag, but it was designed for the ILBE pack.  The inside of this bag is a high-visibility orange color that helps you find contents in the bag easier, or the bag can also be turned inside out to use as a signaling/rescue aid.
