Super Spiral-Stretch System
Offering sweet dreams with superior stretch and comfort for all shapes and sizes
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.
About the material: EX Down
World class, high quality down Montbell's premium down comes from water fowl that live in regions with seasonal temperature extremes. The down balls from birds in such regions are characteristically much larger.
Large down balls hold more warm air, which translates to needing less down to provide exceptional warmth retention.
Lightweight yet warm
When compared by weight to lower quality down, an equal amount of premium down is loftier and has better warmth retaining properties.
About Ballistic Airlight
Ballistic Airlight is made using the same nylon polymer as our Ballistic material and a highly technical production process to create extremely fine, super thin threads. These
threads are then woven into ultralight, gossamer fabrics that share the same characteristics as Ballistic: one and a half times more abrasion resistance than other similar weight fabrics and boasts three times the tear strength of nylons that are almost 20% heavier. Additionally, Ballistic Airlight is often woven using different techniques to create fabrics with radically different characteristics, such as fabrics that allow the garment to stretch or fabrics that "breathe" to release built up heat and moisture.
Woven fabrics typically do not stretch vertically or horizontally without the utilization of heavy elastic materials. However, when stressed along the diagonal the same fabric will show stretch characteristics.
What is EN 13537?
The European Norm (EN) is a test designed and performed by an independent third party that seeks to standardize the way temperature ratings or thermal guidelines are established for sleeping bags.
The history and evolution of Montbell sleeping bags
For overnight hikes or long trails, a good night's sleeping is extremely important. If fatigue carries over to the next day due to a lack of sleep, it can contribute to an inability to concentrate, which could possibly lead to a stumble and maybe even injury. "Warmth" especially is a crucial element that can determine whether or not you get a good night's sleep. Montbell's president Fumiaki Masaki will take us through a history of sleeping bags in Japan, the transitions in insulating materials, design and functionality, and the ever important concept of "warmth".
POLKATEX: World class water repellent
Compared to standard water repellents, POLKATEX is world class water repellent due to its lasting durability. POLKATEX not only repells light rain easily, it also has oil repelling properties making it resistant to staining as well. Montbell's original application technique prevents POLKATEX from peeling off due to abrasion or washing, two of the most common reasons a standard water repellent will wear down over time.
