A progressive and versatile 3 in 1 coat, the Revolution is much more than purely a technical change robe. The outer Parka features 10k/8k Waterproof protection with PFC DWR, and is quilted with 3M Thinsulate, providing outstanding insulation, trapping air and blocking radiant heat loss, while allowing moisture to escape. The inner fleece is moisture-wicking and can be worn whilst wet. It's also easy to remove and wash. Use the two independently, or combine them together for super-warm protection.
