Hyperlite Mountain Gear Metro Pack

A waterproof pack that weighs no more than a garbage bag and can fit in your back pocket.

At just 5.8 ounces, Hyperlite Mountain Gear’s Metro pack weighs only a bit more than a heavy-duty garbage bag, and it’s so small you can slip it into your back pocket. Most impressive: it’s cut from the same material used in sails and blimps, so it’s waterproof, and it’s 10 times stronger than steel.
