- The perfect companion for backpacking and camping. The Montbell Super Spiral Burrow Bag #3 features the patented Super Spiral Stretch System and Exceloft insulation.
Montbell's Super Spiral Stretch System was born out of a desire to have a form-fitting sleeping bag that would let you move freely. A bag with a close fit for thermal efficiency, yet a stretch fit for comfort. These two conflicting principles led Montbell to create their Super Spiral Stretch System for sleeping bags that fit like a glove but give you room to move.
With Montbell's Super Spiral Stretch System you get a closer fit which means one thing: a warmer more efficient bag. Montbell uses an elastic stitching technique to draw the insulation closer to your body and keep heat in the bag where it belongs. This stops drafts, eliminates cold spots and improves the bag's thermal efficiency by reducing the volume of air your body needs to heat.
With the Super Spiral Stretch System, you'll experience excellent freedom of movement. The durable, elastic stitching gently stretches with you as you move. The result is a bag that keeps you toasty warm while accommodating changes in position.
When you choose a sleeping bag, the insulation is just as important as the design. MontBell's Exceloft synthetic insulation in sleeping bags help trap warm air and retain loft. Not only is Exceloft great at keeping you warm, but the combination of 8-denier compacted polyester tubing with extra-thin, 0.7-denier polyester thread makes the insulation remarkably compressible. In addition, Exceloft absorbs very little water, making it highly resistant to saturation and extremely quick to dry.
The inner draft cover reduces air circulation through the zipper area. Auto locking zipper has been integrated to limit zipper slip during the night. Right and Left zip models can be zipped together.Shell:
