Lululemon Rest less Pullover Black / Black. Get up, get dressed, get out there. This warm pullover was designed to be worn under your rain coat on wet commutes or under your ski jacket on the slopes. Brushed fabric feels soft against your skin, a seamless construction in the body minimizes chafing, and thumbholes help keep your arm warmers down to hold in heat. Made to be form fitting. Brushed fabric is soft against your skin. All tags have been removed. Sizing is based off the bars or lines inside the hem. This top contains 4 (see photo), so I am assuming it is a size 10.
