These mittens are durable, super toasty, and functional. I have a lot more flexibility in these mittens then I did in the OR Cornice ones I used to own, and they are just as warm. I have only used in about -20F windchill, but my hands were still warm at that temperature. The leather grip makes them easy to use, and the removable liner is awesome for drying them out at lunch on ski breaks when the weather is a bit warm.

These are very warm, and that is also the problem. I use them only for the coldest days, when I know my fingertips (frostbitten years ago) will hurt with winter gloves. Wearing them while skiing in average winter weather--say 15 degrees F or warmer--is uncomfortable because they are simply too warm!
These are well made, fit well and should last a long time.

Heli mitts are the warmest. I have worn mittens all my life. Now I believe I have found the best. Thank you.

I use these in cold weather on my motorcycle. They are great. The large cuffs go over my coat arms and keep the 70 mph air out. I've worn them in the winter at 15 above F and 70 mph, and stayed warm. The elastic wrist band attachments are handy to keep the mittens from blowing away / falling off when you take them off.

Excellent glove. I have had them for about 5 years and have never had cold hands in them. They also don't show any signs of aging at all. The interior liner might be the softest I've ever felt, and it's removable, which is great because they're are so warm that it is good to have a lighter liner on hand (no pun intended) to swap in on warmer days.

I think I wear the Hestra Heli Mitt more than any other glove or mitten all ski season, which is probably about 120 days for me. My hands get cold quite easily, and it is extremely rare that my hands get cold in these. The leather palm is nice and supple, and plenty grippy, and my hands are almost always dry. I use them without the wrist straps, which seem a bit over the top. If you condition the mittens with leather balm regularly, these will last a nice long time. Mine are coming out of their third season, and they're still holding really strong!
