MontBell has adapted a classic tailor's trick by integrating a woven fabric "cut on the bias". By orienting the fabric's warp and weft threads at 45 degrees to most major seam lines the sleeping bag becomes more fluid or elastic in nature. Additionally, coiled or crimped fibers are used in the fabric weave to capitalize on their inherent stretch properties. To create an even more comfortable system they utilize an elastic stitch technique to create small "gathers" in the quilting. By combining this stretchy fabric, strategic seam orientation, and the elasticized gathers MontBell offers unrivaled fit and comfort. These innovations allow the sleeping bag to stretch with you as you change positions throughout the night, drawing the insulation closer to your body and eliminating drafty dead spaces. Keep body heat inside your sleeping bag, where it belongs.


  • Super Spiral Stretch System
  • Multi-Tube Construction with Flow Gate technology
  • Heat saving Tunnel Hood
  • Draw cord for face hole adjustment
  • Neck Baffle: a shoulder collar prevents air circulation through top of the bag
  • 67 in. mating right & left hand zippers
  • Auto Locking Zipper to limit zipper "slip" during the night
  • Tapered, bias stretch stuff sack for easier packing
  • Cotton storage sack included
  • Double draft tube for increased zipper draft protection

      Comments about U.L. Super Spiral Down Hugger #1 Sleeping Bag (800 Down):

      I bought this bag for a fall trip to Wyoming's Wind River Range. I have owned other Montbell products, but their sleeping bags are simply the best. Extremely light weight, very roomy, warm and well made. The temperature ratings are accurate. I would very highly recommend this bag. Also, the service at Campsaver is second to none.
