User Review: Osprey Hydraform 3 Liter Reservoir
Price Paid: 30
A must have! I should have bought one a long time ago but never did, but it is a must when hiking for me now. It freezes up bad when it -15F but I don't blame it.
Great fitting in the pouch in my Osprey pack minus the weight of the water but to have to not remove my pack every time to get my bottle its totally worth it to leave the house with a full water bladder and start covering ground.
I would have paid double once I realized how much I loved it.
