I used my wingsuit without having it extended. Underneath it, instead of using a polar suit, I used: thermal underwear, a fleece skydiving suit I had from PF, a fleece jumper, a ski anorak (thin), mountaineering gloves with undergloves, big socks and simple mountaineering shoes. To protect the head and face a balaklava and ski goggles. Surprisingly, and I think the adrenaline rush helped a lot, I wasn't very cold, took me one hour on the ice (drinking champagne and taking pics) to start feel the cold. Thanks for notocing the limk error, will correct it asap, and the NP pictures should soon be there! Blue Sky And remember: only SkyFlyers REALLy know why birds sing!
