Having previewed their Fall/Winter 2011 Gadgets Collection a little over a week ago, Carhartt announces their latest collaboration sleeping bag with German outdoor brand, Salewa. Congruent with this season’s motif, Carhartt chose the Sigma Flex 1 model and adapted it using a muted military green and camo color palette. True to the Salewa’s designation as a suitable cold weather accompaniment, the bag is suitable between -15°C. to +5°C. Lined with down duck feathers, the camouflage interior features a small compartment for valuable essentials while the exterior fully zips to firmly cover all extremities. The Sigma Flex 1 retails for ¥33,600 JPY (approx. $437 USD) and comes condensed in a matching nylon compression dry bag.
