A front zip makes it easy to put on and take off before and after your workout.

The Zipsera sports bra is designed with a full-coverage, wire-free form for training days. A zip closure at the front makes it simple to get on and off, which is handy before a session and when you are changing afterwards. The seamless construction and fitted line give it a sporty character that sits neatly under or with other workout pieces. It is a straightforward piece for anyone who prefers an easy, no-fuss way to get dressed for training.

Straps cross over at the back for a distinctive shape, and the wire-free construction means there are no stiffening elements in the lower part of the cups. The full-coverage cut covers the upper torso for a streamlined look. Wear it as part of a workout outfit with leggings, shorts or a sports sweatshirt, or layer it under a loose top for a relaxed gym look.

Choose from black, grey, pink, white or blue, in a wide size range from S to 5XL. Check the size chart before ordering and choose the size that feels comfortable for your activity. Wash it according to the care label, ideally in a mesh bag with the zip closed, and let it air dry. Check the fit before higher-impact exercise, and replace it if it stops feeling comfortable.
