Bladder: 70 ounce hydration engine, quick-release valves for drinking tube and pressurization tube for easy refill and bladder removal, slide top for easy refill, cleaning and drying.
Fabric: 100% heavy-duty 840 ballistic nylon. 1680 ballistic nylon panels (if the Marine Corps can rely on this fabric to deflect shrapnel then it is worthy material for Geigerrig packs).
Removable Waist and Shoulder Straps: If you would rather not ride with a pack then remove the straps and waist belt then strap the bike bag to your tank or bike seat and re-attach them when you reach your destination. The Shuttle Bike Bag was designed to wear with or without chest protectors.
Weight: 3.00 pounds or 1.36 kg.
Additional Features: Designed for versatility. This heavy duty 840 ballistic nylon pack can attach to about anything. All of the pack straps detach, including the waist strap. The pack has a unique "handled" design that allows for many attachment and detachment points for strapping this pack to vehicles, bikes, and gear. There are two independent, vertical zipper pockets for holding a phone, granola bar, treats, map, car keys, etc. Remember, the detachable, hook-and-loop bulb holder will allow you to connect your Power Bulb to whatever you would like to, including the various attachment points on the Shuttle itself. And, don't forget to get yourself a Geigerrig In-Line Filter - you never know when you might run out of water and may need to refill from a river, stream, lake, or pond.
