I just wanted to let you know that I climbed Mt. Hood on June 16th and wore the Altitude Mitts throughout much of the climb. We had an alpine start (around 2 AM) and the weather was very cold. My biggest fear on this climb was frostbite on my hands, and I was delightfully surprised that my hands were warm as toast with your mitts. I also like the wide opening and tightening strap (instead of elastic which makes it difficult to gets hands in and out). You have an excellent product.
Thanks very much!
