Title: BAH- no longer in my backpack gear.
Review: HEAVY , and doesn't carry enough water to justify the weight.SUCKING HEAVILY- is what you'll do to try and get a SIP of water out it . Plus you have to squeeze the hell out of it to get H2O out of it.I think I burned more energy trying to drink water than i did on the hiking trip...I've now switched to iodine tabs after this expensive lesson.
