Women's workout shirts and tank tops have evolved so much in the past decade, with famous sports and activewear makers competing to get the most important tech features included. Moisture wicking is one of the most popular tech features, as it pulls wetness away from you to keep you cool and dry. Quick drying knits are popular, as is anti-odor tech to keep you smelling fresher longer. Many styles feature SPF protection factors, to let you know how well you're protected from the sun. Polyester fleece jackets and tops are perfect for very cold weather, especially when layered with other sport tops. Many styles are designed especially for yoga, with casual styling that can be worn with your jeans as well as when doing the "downward dog." Plus size women's sports tops are also making their presence known in this arena.
