RW has two types of gear...the original gear and the lighter version for warmer temps.
I own the original RW ambush jacket and pants....bottom line....love it and hate it. I hate it because it is too warm and I can't wear it when it is warmer than 50deg. Love it because I dropped 1 full layer clothing, waterproof, windproof, durable, quiet, really insulates the snow well (Did some sniping in the snow last deer season and I layed in the snow for 3 hours and never got cold.)
You really can go wrong.
