Artilect Women's Sundown 250 1/2 Zip

From New Moon:
"My Artilect layer is my new favorite piece. It works equally well as a stand alone or as a base layer. Very good breathability, sweat management, comfort, and some nice wind protection as well - I tested it roller skiing at 48 degrees, and I was cruising at 10mph. I'm really looking forward to wearing for more activities - paddle boarding, trail running, xc skiing" —Joel
