The Under Armour Women's HeatGear Armour Long Sleeve is a great base layer top for women who do Pilates. It is made with Under Armour's HeatGear fabric, which is ultra-soft and smooth against the skin.

The four-way stretch construction allows for a full range of motion, while the ergonomic flatlock seams prevent chafing and irritation. This top also has a shaped hem for enhanced coverage.
