These mitts rule, my 3rd pair. And for the price, wow. They are waterproof, and very warm. However, in warmer conditions they aren't unbearable, gore-tex to the rescue! Even if you do get cold they have zippers on them for inserting heat packs, and inside one of them there is even a goggle wiping cloth. If that isn't enough, they also have a soft nose wiping material the right thumb and a goggle squeegee on the left thumb. And to top it off they come with mitten style liners for extra warmth; but they're great for hiking or real warm temps too! So, to sum it up these are awesome for the price. Besides, you know you're going to stink 'em up eventually and need to buy new ones, so you don't need expensive ones.
The other review that mentions their quality might be partially true. I had the drawstring come out of one once, but warrantied it. Otherwise, they're pretty tough. I didn't bump any ski chairs, but I operated my snow blower, shoveled snow, and skied in them for 100+ days combined.
