Familiarity: I've used it several times
First time I have used mittens and they have been great in these bitter cold days in the northeast. It was -20F the other day with the wind and i used a light glove liner with a hand warmer and I never felt any cold. The gloves are a little slippery for holding poles, but that might just be my adjustment to a mitten. I really like how high they come up on my forearm.
