The Maxpedition Noatak Gearslinger delivers a durable exterior and highly functional design. The 1,000 denier nylon fabric has an extra layer of protection thanks to a DuPont Teflon treatment that guards against grime and a triple polyurethane coating for superior water protection. When worn on the back, this bag can be rotated 270 degrees towards the front of the body for quick and easy access to contents, an especially useful design feature when sitting down. The front sleeve has an anti-theft device on its zipper, while an exterior water bottle pocket is sized to hold bottles up to 32 ounces. Stitched with high tensile strength nylon thread and with reinforced stitching at high stress points, this durable backpack is built to hold up in tough conditions.
