Back when i had a discount on Patagonia stuff i bought their baselayer bottoms and tops--capilene, almost couldnt remember the name--and the heaviest weight ones are incredible for how thin/light they are. These baselayers help you avoid too many layers. After about 3-4 you start looking and moving around like the kid from a Christmas Story. Another product plug is for these socks they made at one time. They had a stupid expensive retail price tag like $60-80 for a pair of socks, but they are the thickest socks ive ever seen. Nothing special about them,just really thick merino wool socks. Anyways, after buying the above items at a steep discount and wondering aloud, "who would pay full retail for this stuff?", i would pay full retail for the stuff now. Its something you need one of and not twelve, and I was glad to have the stuff for hiking trips out west, to iceland, and of course winter fishing.
I still need to figure out the hands stuff. I had full neoprene gloves, and they help a bit, but its really difficult to fish effectively without a decent level of dexterity. Wanna try some type of wool fingerless glove this winter.
