I wore it when the week temps were a balmy 25 degrees on the north slope, mixed sleet, wind, rain, snow and a tiny bit of teasing sunshine during the day, in Aug. For me temp was fine, never did I get too hot carring a pack and never did I get cold, when stopping to glass, rest etc.... Anything lower than 15 or so, probably wouldn't cut it unless your moving, it is a early season gear for Alaska, I wouldn't recommend it for a late Oct hunt for Moose. On the westside of the this state, it would probably work throughout any season, I guess it really depends upon the person and their comfort range.. It is designed for folks that move around, If I had a tree stand, I probably wouldn't wear it for an all day event clothing..... As for drying, it dries twice as fast as anything else I have, had the chance to really see when my buddy had his set and I didn't at the time on a Kenai Pennisula Goat Hunt. I had 3SP Mountain pants and other high quaility gear, It just wouldn't dry, period. Even my nylon super light weight pants wouldn't dry in the 6 days of complete down pour, but his pants and top did, nothing else under the tarp did! I'm a believer. It worked for him and me on latter trips as well. Use in Cold Weather, 15 and lower, well that what they design cold weather gear!
