So I lost *every single* Icebreaker piece I've ever owned to moths, despite being stored with cedar blocks and prominently displayed signs saying "Please do not eat my wool." Switched to Phase. Haven't looked back. Dries massively faster than merino equivalents, in my experience. The ARs are warm enough for most anything you'd want to do actively even in deep winter; SLs are equally nice and awesome to sleep in. Will stink a tiny bit if worn days on end without washing, but not nearly as bad as other syn baselayers I've tried. I'm sold.
