Seamless Alpine Burrow Bag #1

The Seamless Alpine Burrow Bag, the lightweight version of Montbell's synthetic sleeping bag, provides an optimum balance between weight and warmth. The synthetic insulation offers advantages in wet or humid conditions, and its seamless design allows the insulation to maintain loft to its fullest while preventing heat loss through the seams and efficiently holding your warmth. Spiral Strech System on the lining features bias-cut fabric and oriented seam lines, resulting in a stretch that gently follows your body. Well suited for winter conditions at moderate elevations.
