Lightweight layering piece, excellent quality

Just as described. Lightweight layering piece. I just wore this with a super thin Mammut base layer underneath and Mammut Aenergy hybrid soft shell back country skiing in Northern Minnesota. Great piece, functional and not bulky. Temps were mid teens. I wear around town as well. Comfy grid pattern against your skin. I wear a large for pieces like this. I wear Xl for jackets when layering underneath if that my help with sizing.

light but very warm

This tech shirt is awesome. I bought it as a base layer for skiing and love how light but warm it is. It fits great and looks great. True to size.
