I came here to say Costco. If you are fortunate enough to afford the membership, or if you have a friend with a membership, you can find full, heavy duty, name brand outdoor gear for like $120. I got -40 winter boots for like $35 one year. You can get a pack of winter wool socks for $7. I got a waterproof winter weather system coat for like $45 a few years back. Underwear, lined pants, balaclavas and gloves are all there.
