Jim, I'm Ignacio Martínez, from México. If you remember, I with 3 other friends, Hector Martínez, Joaquin Rubio and Francisco Milmo, buy the clothing system to hunt Polar Bear. I hope the information I send through this e-mail, might help the company in making better clothing. 1.- The Jacket and the pant, were incredible. We were practicly in -40° for about 9 days and we were never cold. We did what the company advise us in using the underwear, but after a day or two we felt that we have to use another layer. A lite one. That's when we never felt cold. We travel in a sled, and sometimes the wind was strong, and neither in that case we felt cold. The only time you could feel the wind or cold, was when you realize the velcro wasn't perfectly closed. 2.- The boots. They were incredible. Since we were traveling and not moving, I thought that we were going to freeze. That never hapened. One of the thing's is that if you walk (when you climb an iceberg) your feet swet. Nevertheless, our feet kept warm. After that, you could feel the moisture in your feet (kind of feel like wet), but even do we expect to freeze, that never hapened. In the night we took the insole and by the morning it was perfectly dry. We wore them as told, only the linen sock. The only bad thing is we feel the boots are not good for walking. 3.- The anorak top. I was the only one that wore it, and it was perfect. It kept the wind from cooling me. 4.- The severe hood was good only for Francisco. Hector, Joaquin and me stop using it since we felt it obstruct the sight. The balaclava or what goes in your face, was imposible to use it. We all felt that. It was very high and you couldn't see. It blocked the sight. And with the movement and the wind, it wen't out of the severe hood or the jacket, and the wind and cold started to freeze our jaw. 6.- The sleeping bag was perfect, incredible. One time I was in the tent at -20° and I sleep in normal underwear. The temperature inside the sleeping bag was always around 23° to 26° celsius (not farenheight). Sometimes it was hot. The only thing is we don't understand why is so long. Overall everything was perfect. I don't think there's better clothing for arctic weather than Northern Outfitters. Thank you and I hope you benefit from my experience. I was 9 days in the arctic and you are always struggling against the cold and the warm, so you analize everything. Ignacio Martinez
