Thanks! I've been shopping REI. I've gotten a heavy merino base, which everyone says is too much, but I'd rather have it since I get cold so easily; and a light ( 185) merino base. I'm looking at their fleece pants, hoping they might go on sale. Based on all this wonderful advice, I've ordered a merino wool gaiter and waterproof glove. I'm renting the boot,. I have waterproof rain pants, or may rent theirs. I went thru my closet and found a few fleece tops and turtlenecks that work... after all, its a short cruise, 4 days travel ( back and forth across the Drake) and 4 days in Antarctica. Time didn't permit the addition of the Falklands. Plus I'm going as a single,... ... which makes it quite pricey.
thanks again. This group is a wealth of knowledge and experience!
