Marine Corps Systems Command intends to award sole source purchase orders for two types of Intense Cold Weather Boots and Intense Cold Weather Socks to improve Marines’ performance in cold weather environments. A total of 2,000 boots and 50,000 pairs of socks will be delivered from four vendors by Sept. 28. The socks will have much higher wool content than the polypropylene wool socks Marines currently use. A field user evaluation will be conducted December 2018 through March 2019. The team will gather input from Marines as they wear the ICWB and ICWS prototypes. The U.S. Army is conducting evaluations with similar boots and socks. For more details, see this KitUp! article.
