Just got these on Friday after a wicked deal on S&C. Looked at tons of gloves and styles this off season, and was ready to pull the trigger on the Hestra Helicopter glove, even with the stiff price. Started looking into undercut gloves since my parka has larger cuffs, and had to jump on this deal.
Pros: almost everything about this glove is amazing. The goat leather is extremely supple, and there is no break in period. The padding on the back of the glove keeps the back of your hands warm, but the fingers are still extremely flexible. Gloves fit great under the sleeves of my parka, which was a major concern for me. They certainly wicked the moisture away from my hands (I tend to sweat a ton in my old Marmot gloves) and I could see the moisture darkening the leather between the fingers but my hands stayed dry. I was concerned about some of the other reviews that said these were really warm, but they were comfortable on a sunny, warm day around 25 degrees. I got the gray/tan/black ones and the colors rock.
Cons: my only concern about the glove so far was the liner pulling back out of the fingers a bit when I took them off at the end of the day. I have had this issue with other gloves in the past, particularly when the liner is not sewn to the shell. It was minimal, so not really detracting from my overall impression of the glove.
Overall, this was a great choice to replace my 8 year old, packed out Marmots.
