These mittens are awesome. They are very warm and the features are great. Unlike the product description these mittens DO have a goggle wipe and they DO have a nose wipe. They are great. I wore them on a 30-degree day without the liners and they actually made my hands pretty sweaty. They must be way warm with the liners, which themselves are great also. They have a very sticky material spread out all over the palm and fingers which make it very easy to grab things like cameras, or anything really.
The compartments on the back of them are perfect for small heaters or for stashing some keys or other small things. The wrist cinch is wonderful; I think Burton came up with a great system (which is new to me but others might be very familiar with) where you pull on one side to tighten your wrists and by pulling on the opposite side it comes lose.
Overall, these mittens are the best I've ever owned, above any gloves I've ever had.
