I recently returned from a 5 month deployment to McMurdo Station on Ross Island, Antarctica. During that time, I was privileged to have the opportunity to spend two weeks at a field camp on the West Antarctic Ice Sheet, where various groups are doing ice core drilling to research climate change. At the field camp, there are no cozy dorm rooms. In fact, there are no permanent structures whatsoever. The 40-odd people who spend their summer there do so in tents. I was issued a High Peak Cascade -40 sleeping bag to use in my tent, and I was extremely happy with how toasty it kept me despite temperatures that did, in fact, get pretty close to -40. Believe it or not, I actually hated leaving it to return to my dorm room at McMurdo. I just wanted to let you know, if you didn't already, that your products are being used in the some of the harshest conditions on earth, and that they are more than living up to expectations. Even a little bit of comfort can mean a lot when you are living on a glacier! Thanks for making such a great product.
