Lowa, with gore lining only, although they are leather lined on the interior. Work great from Alpine forests snow (Sheephunter) in winter to Sept AZ deserts (Baffin). Almost no break-in and super comfort, the taller Sheephunters have very good ankle support for the rough stuff. Follow their recommendations for care, a lot of guys put goop on their boots which stop the breathing and makes boots hot in summer and when you sweat, and you do even in the winter, your feet will get cold. Don't like boots with insulation linings as they are not as efficient as good quality socks at wicking away moisture and keeping your feet dry/warm. Unless you have got an Alaska hunt coming I would avoid linings.
