ULtralight Super Spiral Down Hugger #1, Long, Right Zipper. Super Spiral Stretch System PAT. Multi-Tube Construction with Flow Gate technology. Draw cord for face hole adjustment. Heat saving Tunnel Hood. 170 cm mating mating right & left zippers. Auto Locking Zipper: a locking mechanism has been integrated to limit zipper slip during the night. Tapered Stuff Sack: A tapered opening and “bias cut” fabric are utilized to facilitate easier packing. Probably the most comfortable sleeping bag ever made. Cotton storage sack included. 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 MontBell utilizes 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. MontBell increased the stretch from 1 to 3 inches to a whopping 18 to 22 inches. Its nothing short of brilliant, says one 6-foot tester. I can comfortably sit in full lotus position, but when Im in repose, the bag snugs up around me to eliminate pockets of dead air. Plus, by stretching only where you need it (lets say you want to splay your lower legs a bit), the insulation stays close to your body in other places, which increases overall bag warmth. I slept directly on a sheet of snow after my sleeping pad failed, and even with temps in the upper teens, I stayed warm enough to get a decent nights sleep, says one tester after a weekend in Colorados Sangre de Cristo range. Backpaker dot com. This year’s winner is the 15-degree bag from Montbell. Better is how one tester sums it up. The Ultra Light Super Spiral’s major tech innovationspiraled bafflesmade it the most comfortable and best-functioning bag we tested this year. Far from a gimmick, the spiral baffles drape more evenly over the body, creating a closer fit. And because the seams are sewn with elastic thread, the bag literally hugs the luxurious, top-shelf 800-fill down insulation to your body at rest, and expands by up to 20 percent when you move around. We could actually sit up and cross our legs inside ita boon for restless sleepers. Another benefit of the diagonal construction is that the baffles are longer, meaning fewer seams to let heat out. All this in a tiny package: The gossamer-light 12-denier fabric and high-grade down make for a bag that packs to the size of a bread loaf. The Down Hugger #1 is designed for comfort in cold, alpine environments. Rated for between -5 and -11 it’s perfect for hiking up into the mountains of Tasmania, the Southern Alps in New Zealand or Kilimanjaro. Using the famous Montbell Bias Stretch and Super Spiral Stretch system the Down Hugger #1 minimises the volume you have to heat by stretching and conforming to your body and with 800 fill power down the total weight is reduced to less than one kilo. Super Spiral Stretch baffles allow the bag to stretch and move with you. By pulling the bag in around you and hugging your body, the volume your body has to heat is reduced. This allows the bag to provide the same warmth with less down, keeping the packed size and weight down to a minimum. To further enhance comfort, the fabric is Bias Cut. By having the weave of the fabric run diagonally in relation to your body, the natural give in the woven material allows for more stretch and greater comfort.
