Arena Optimal Short is a close-fitting men’s training swimsuit with a short leg and approximately 27 cm side length. It covers the upper thigh without the extra volume of loose beach shorts, making it suited to laps and regular pool sessions.
A front lining provides additional coverage. The streamlined cut avoids loose fabric gathering in the water and is intended to sit closely against the body. Check the arena waist and hip measurements when choosing a size, since a fitted silhouette is central to this style.
