The Rab Alliance Mitt is a very warm, very durable & very versatile modular mitten system. It features a Primaloft insulated e VENT waterproof & very tough outer & a Primaloft insulated inner that can be used independently or together depending on the conditions. The outer Mitt is constructed from Rab’s own Matrix DWS durable nylon stretchy softshell fabric, is fully insulated with 133g/m² Primaloft insulation & is reinforced with Pittards Amortan leather. Amortan leather is made super durable by encasing the natural fibres in microscopic ceramic armour plates thus preventing wear from surface contact & materials. As well as the Amortan treatment this quality leather also features Innovative Grip Technology; this is a polymer infused into the surface of the leather to increase grip without compromising dexterity. these technological fabrics are backed up by the reliable & durable e VENT waterproof & breathable membrane. The outer provides protection & insulation & features a Bemberg brushed lining for comfort & moisture wicking. The inner glove is fully insulated with 133g/²m Primaloft synthetic insulation & covered with Pertex Microlight fabric to provide wind-proofing & water resistance. Thanks to the fantastic performance of the inners they can be used on their own if the conditions are not extreme. Should the inners get wet they will continue to provide some warmth & will dry very quickly. Combine these two & you have a full on winter mountaineering system capable of dealing with pretty much anything the UK or the Alps can throw at you.
