Reviews

A bit disappointed with the

"A bit disappointed with the sizing compared to previous versions. The trunks are noticeably longer than they used to be, and the fit feels less consistent, even within the same pack. The fabric is still comfortable, but the sizing has become a bit unpredictable. I preferred the older cut and hope they bring back a more consistent fit."
