I had ordered Arcteryx Fission gloves and found them to have a bizarre and unacceptable fit, so I ordered a 3 others that seemed similar, including these. These won and were kept. The fit is true to size, and my fingers reach the end of the glove's fingers, which helps with dexterity. In fact, given how warm these are, they're very dexterous.
They come with wrist leashes that can be easily removed, if you don't want them on the glove. They have a loop at the base of the gauntlet to help pull them on, although they go on easily anyway. The leather is very soft. I was afraid the leather on the back across the base of the knuckles (where the embossed logo is) would be stiff, but it is soft and pliable. They can be cinched tight at the wrist and the end of the gauntlet with one-handed operation to tighten and loosen.
They have either Helly Tech Professional or Helly Tech Performance membrane. I say "or" because the tags that come with them say both! The Professional is like 20,000/20,000, and the Performance is something like 15,000/15,-20,000. Either way, they keep out heavy wet snowfall during storm skiing, and they seem to breath pretty well. They are very warm, and anything over 30 degrees may be too warm...unless worn with the closures open wide. For a typical ski day in the teens and 20's, they're perfect. Also light with impressive dexterity.
It is still early, but I'm thinking these may be the best overall gloves I have ever owned. And they're nearly 1/2 the cost of the less warm Arcteryx Fissions. Strongly recommend.
