SEAMLESS DOWN HUGGER 800 THERMALSHEET Long

SPIDER BAFFLE SYSTEM

To prevent down from shifting and producing cold spots, sleeping bags have been traditionally made with inner walls called baffles. The Seamless Down Hugger series is the world's first sleeping bag to remove the traditional baffles. This radical construction technique produces a sleeping bag with a single, continuous chamber and allows the down to loft to its fullest potential. This technique doesn't affect the lightweight and compact nature that Montbell's sleeping bags have become known for. The next generation of sleeping bag is here!
When looking for a suitable baffle replacement we received a little inspiration from nature, the spider. The thought was, "If we could make a web inside the sleeping bag, it could suspend the down and hold it in place, keeping the down from shifting." Based on this initial concept, work began on developing a specialized thread that could trap and hold down. Calling this new thread "Spider Yarn," we were successfully able to suspend a layer of down throughout the entire bag. This new construction is the "Spider Baffle System."
