GoLite Jam 70L Gray Backpack

Size Large fits up to 48” waist.  Torso length 22” Weight: 1lb 15oz Capacity: 70l Design: Frameless Totally Carrying Weight: 30lb Maximum MSRP: $129.99 Available From: http://www.golite.com  The design of the Jam Pack is relatively simple. The main compartment is 70 liters (as the name implies) and has a roll top so it can expand or be rolled down depending on the amount of gear your hauling. There is room in the main compartment for a 3 liter hydration system of your choice and two ports at the top so your drinking line can come out either side.  There is also a hook at the top, presumably to hook your bladder to – however my Platypus bladder’s top doesn’t fit into the thin hook design.  I’m not sure if they had another system in mind here or whether this is just a frustrating minor flaw
