Our classic Thinstrap swimsuit, updated. We’ve given our classic Thinstrap swimsuit a fabric upgrade, so it offers even more benefits. Retaining its wide-open back and thin straps for unrestricted shoulder movement, and the high cut leg for maximum flexibility during training, it’s now made from our durable ECO Endurance+ fabric. Quick to dry and 100% chlorine resistant, it’s ideal for regular training sessions. Plus, one of the yarns in the fabric is made from 100% post-consumer waste, such as recycled plastic bottles.
