Synthetic shirt/pants. That's what I wear for snowshoeing, canyoneering, backpacking, day hikes. For snowshoeing, I wear a Patagonia capilene base layer with Marmot Precip Pants, and a Marmot Cobra shell, this keeps me warm and dry. If it get's too hot, I open vents and or un-zip and use the snaps instead. For canyoneering I wear synthetic shirts pants again, this to keep me cool and dry quick. This year, for snowshoeing I might try a softshell jacket and a capilene base layer, hopefully it does not snow, lol I hear some are waterproof though. I can always put the Marmot Cobra over the softshell. Another option is a base layer, 100 weight fleece, and shell. My Marmot Pre-cip pants are water proof, I could also use the Pre-cip top instead of the Cobra, since it is also waterproof and lighter.
