Under Armour Base 3.0 Crew Top - Women's 2012 - Base 3.0 is for maximum warmth in the coldest conditions. Strategically placed ergonomic seams add to overall comfort by reducing abrasion in high impact areas. The Under Armour Base 3.0 Crew Top is built with Flatlock Seams that feel smooth against the skin and prevent chafing. Raglan sleeve construction allows for total mobility and a full range of motion as you ski or ride, while eliminating shoulder seam abrasion points. Plus, ArmourBlock® technology neutralizes the microbes that cause odor before there is any odor at all, which results in moisture transport with maximum scent suppression so you will be smelling so fresh and so clean at the lodge after riding.
