By adopting a classic tailor's trick, using only the best materials available, and re-imagining a trusted mountaineering concept, Montbell has brought unparalleled comfort and thermal efficiency to minimalist backpackers and alpine climbing enthusiasts with our Down Hugger Half Length Series. The lower portion of the bag offers ample room for movement by incorporating our Super Spiral Stretch technology (US.Patent NO. 7,900,301) that deftly draws the 800 fill power goose down closer to you, while eliminating drafty dead spaces. To insulate the upper body, pair a Half Bag with one of the many Montbell down jackets available and utilize the ultra-light nylon top collar to seal in body heat. Better manage temperature and comfort by opening the foot zipper to release build up body heat and moisture throughout the night. The beauty of the Half Length Series is pure versatility. First, users are able to extend the utility of an item already carried into the backcountry; the down jacket. Second, we offer 2 different loft options allowing users to tailor their sleep system to the season, region or climate frequented. Finally, users can personalize the system with down garments of varying thickness to accommodate for individual thermal requirements. This modular approach puts you in control. The construction of the Half Length #5 is based on the thermal profile of the Down Hugger 800 #5. This equates to a moderate lower bag suitable for summer and warmer season usage. Of course, with a modular system like this, layering effectively will be paramount to being able to rest comfortably. In order to protect your upper half from the cold, you’ll need to be wearing an equally thick down jacket. Jackets in the Montbell lineup that would pair well with the Half Length #5 would be; Superior Down Parka, Plasma 1000 Down Jacket and EX Light Down Anorak.

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, to create an even more comfortable system we utilize an elastic stitch technique to create small “gathers” in the quilting. By combining the strategic seam orientation and the elasticized gathers we offer 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. By using a sleeping bag with Super Spiral technology you keep body heat inside your sleeping bag, where it belongs.
