Slightly bulky, but after you get it on the gloves stay warm and the battery will last a full day as long as you use it intelligently.

Best For The Worst Weather!

These work best in frigid, single digit temps like what we have in mountains of Colorado. The mittens by themselves without the electric heating are enough for temps in the low double digits. Dexterity is what you expect from a mitten - you learn to use your thumbs! Quality of materials and construction seem solid - time will tell. Sizing seems spot on.

Too Big!

The mitts are well-made, but the sizing is off. I wear a unisex small and they are much larger than any other small mitts I own, including those from OR purchased earlier this season. They are bulky, so I don't have much dexterity when wearing them. Contrary to other reviews, I don't find anything weird about the thumb.

Very comfortable and warm, with multiple heat settings.

Really Great Quality Gloves

I bought these for my girlfriend as a gift. She has reynaud's and has had really cold hands every single day we have skied, even in the spring! These gloves have completely changed her skiing experience and keeps her going for a lot longer! She rarely goes above the lowest setting, except for when on a cold chair lift. Really impressed with these. We ski 70+ days per season and so far she has used them every single day. Battery life is pretty good! There seems to be better out there for battery life, but get a spare and always have them charged and you're set!
