Made from ultra-soft bamboo, these trunks are designed to sit closer to the body for a secure, supportive feel. Breathable, moisture-wicking fabric helps keep you cool, dry and fresh all day.
Supportive and Smooth
The fitted shape stays in place without riding up, while a soft, brushed waistband keeps things comfortable without digging in.
