I will second the silk socks under wool socks. You can find silk socks at most any Ski Shop. NeoPrene waders. You won't find me up to my chest in icy cold water in mid winter, just out far enough to lay a fly in front of a Steelhead. I mostly fish tail-outs so the water is not too deep. Caution is my friend in the winter. I have a pair of neoprene gloves I bought in Oregon about 8 years ago, designed for steelhead fishing. Thats probably the best part of my winter outfit. I have been fortunate to fish besides Jim Teeny on the banks of the Sandy River in Oregon. Snow coming down, ice on the edge of the water. When you are having a good time and hook up now and then, the cold doesn't seem to be so bad. It's that trip to the truck to shed the wet gear that makes the cold weather more evident. Then of course there is the heater in the cab and the thermos of coffee. Now you got me looking forward to winter and summer isn't even over! Good Luck! Jonezee
