The Rab Alpine 12 sleeping bag has a relatively trim fit: when there is only a minimal amount of space around the body, you get the maximum thermal benefit from the down insulation. This model is suitably warm to serve as a sure-fire three season bag, as well as a mild winter night bag. The bag uses the new L.O.F.T. baffle construction, which reduces down movement inside the chambers and decreases packed size. Down staying in placeespecially when sleeping on your sideis impressively good. Side sleepers have also been considered in the placement of the drawcords and toggles for the draft collar and hood; they stay comfortably out of the way. The down is treated to be water-repellent, as is standard today. In this bag, the treatment is GrangersDown Defend, which helps the down stay lofty in damp conditions and reduces clumping. Grangers products are water-based. - Tapered mummy shape: strongly narrowing toward the foot end - Long size: Suits users up to 200 cm, bag length 230 cm -
