The Variant 37 is a top loading, unisex pack designed specifically for ski mountaineering and ice climbing. Features A-frame ski carry – The reinforced A-frame ski carry loops found near the base of either side of the Variant work in conjunction with the side compression/retention straps to provide stable, easy to use A-frame ski carry. Simply slide your ski’s tail through the loops until the bindings rest on the loop and use the upper compression/retention strap to secure to the side of the pack. EVA foam expedition hipbelt – Each Variant Series pack features a removable/interchangeable EVA foam hipbelt with modified straight ErgoPullTM closure designed specifically for optimal fit, comfort and load transfer/stability. Reinforced gear loops on either side of the hipbelt allow for additional gear attachment points. ErgoPullTM hipbelt closure – To operate, loosen the webbing enough so that you can connect the center buckle. Grasp the loose ends of the webbing on either side and pull in and across evenly with both hands at the same time.
