Have yet to test them in extreme cold.

This is my 2nd pair. The first pair lasted almost a year before they needed to be replaced. They're very warm and very comfortable. I would definitely buy them again.

I work outside the airport driving an open Tug in Chicago. Our winter weather can be very bad with below 0 degrees Fahrenheit wind chill's and a lot of snow. I needed a durable, warm and waterproof work glove for these conditions. I've tried various other gloves claiming my hands should stay warm to -30 degrees Fahrenheit, to which they didn't even come close even when using hand warmers. So, I came across these gloves and my hands have stayed warm below 0 degrees, without using hand warmers. They are well made, easy to grab ahold of things, because of the performance flex material. The silicone dot grip works very well, not allowing slippage, when things are covered with snow. These gloves do fit inside my zip-up coat pocket and are not to bulky or stiff when moving your fingers. Now I don't have to use hand warmers to keep my hands warm. The only con I have, is they are not waterproof.

I bought 2 pairs of these.I am an order-filler at a grocery DC. In the freezer area. It gets down to -20. These gloves are advertised as being comfortable to -30. Theres absolutely no way, my hands go numb and i wear glove liners and hot hands inside each glove. Also, I handle alot of pallets. Now the gloves are starting to tear and fall apart.. And those grips on the gloves wore off within a couple days. Im highly dissapointed in these gloves. Theyre even hard to get on. The cuffs are too tight. I also bought the Polarforce sweater and shoes. Knowing the jacket has the thumb holes in it to wear the gloves over the jacket, why wouldnt yall make the cuffs wider or have a strap to fit over the jacket?! Ive spent alot of money on Refrigiwear apparel. Because it basically says in the name what i need it for. Im happy with the jacket and shoes. Just wish the gloves were waterproof and more durable, basically.
