The stratus mitt is a very warm mitten for the price/weight. It has a durable palm and is completely windproof. The mitts do compress very nicely as well. The only downside to these is that they are not waterproof. Haven't had a problem in regular use in the snow though.
Finally a mit to replace my old HeliHansen's (which are no longer made). Add a thin liner glove and you have great cold weather versitility and warmth. Just like we used to do on Denali in the 80's and now for skate skiing on the negative number days.
While these are great lightweight mitts in their own right, they also make excellent liners. I purchased a pair of OR Verglas Mitts and found that they were a little light for winter mountaineering. Consequently, I purchased these Stratus mitts, slipped them into the Verglas shell and Voila! I had them on Rainier, Shasta, and Hood and they were TOASTY.
These mittens are super warm. I have Reynodes disease and these mittens seem to do the trick. I have only used them to bike around town in high 30-degree weather, but my hands were sweating the whole time. The grip sticks to everything, which is good and bad. Overall, I'm satisfied.
