User Review: Patagonia Men's Capilene 2 Lightweight Zip-Neck
Source: bought it new
Lightweight, dries fast, provides warmth when you need it. Great for all outdoor activities, or just hanging out at home. A bit pricey, but lasts forever and is often on sale.
Breathable and wicks well. Adds just enough extra warmth to regulate your temp on a chilly day. Fit is dead on: 6' 175 lbs. and large is sized perfectly. The arms are a bit long in a good way.
Well made and highly recommended.
