There is nothing more irritating than a confining mummy bag. We just hate them. Introducing the new limited addition Nemo RHYTHM 25 Sleeping Bag. Nemo has pulled the covers off from their 2013 collection, and are offering a limited-time early run. Unlike traditional mummy bags that made you feel like you’re wrapped up tighter than a sardine, the RHYTHMs unique design combines a wide upper torso area, and a flared knee area. Both areas allow you to shift and bend through the night, all while maintaining thermal efficiency. Manufactured from lightweight fiberproof rip-stop nylon shell, filled with the PrimaLoft Synergy continuous filament insulation. This bag is good to 25F /-4C. Other features include fully insulated blanket fold, waterproof breathable foot-bed, and a zippered watch pocket. What more would you want in a bag? The RHYTHM 25 is an awesome innovative bag that is made for mere mortals, not mummies.
