Just the right size for fitting in a tour before work, the CamelBak Phantom Winter Hydration Backpack packs a slew of features. This pack has a separate compartment for your shovel, probe, and skins, to keep your layers in the main compartment dry. The Crux reservoir sits low and close to your back for optimal balance, and uses an insulated tube cover to reduce the risk of freezing. When you have to boot pack, choose a way to strap on your skis or snowboard on from the various carrying options, and unfurl the secure attachment to strap your helmet on.
