Cool Weather Baselayer Extraordinaire
Perfect weight for fall temps. (40s-50s). Under a wind shell a great combination for hiking, maybe a little warm for running. Icebreaker merino is super soft. Doesn't hold odor. Wicks well and dries fast and doesn't feel clammy even when drenched in sweat. Cut is very athletic, as in skin tight, so if you like something looser, go with Smart Wool. It's stretchy though, so not uncomfortably tight. I just wouldn't wear it around town. A little too revealing for that. Slim is good work working out though. The collar height is nice, not so high that the zipper rubs under the chin. I like the raglan sleeves too (i.e. no seams, flat or not, on shoulders to chafe under pack straps). The zip could be maybe and inch or two deeper for more venting.
