82% Polyester and 18% Spandex
Your Underwear, Now Pool-Ready. The Desmiit S312 swim briefs bring the same confident low-rise fit — now in a durable, quick-dry fabric built for water. Available in 7 colors, these swim briefs are designed for the beach, the pool, and everything between.
Designed for Water
Crafted from 82% polyester and 18% spandex, the S312 delivers the perfect balance of stretch and durability. The chlorine-resistant fabric prevents fading and damage from frequent swimming, while quick-dry technology keeps you comfortable long after you leave the water. Built-in UPF50+ protection shields your skin during long days in the sun.
Low-Rise Fit
The low-rise cut sits low on the hips with minimal coverage, creating a sleek, athletic silhouette that flatters your physique. The exposed elastic waistband provides a secure fit without riding up or shifting — whether you are diving into waves or lounging poolside.
7 Colors, One Essential
From classic black and navy to bold red and yellow, the S312 lets you choose the color that matches your style. Each pair delivers the same consistent fit and performance across all 7 options, making it easy to build a swimwear rotation for the entire season.
Size & Fit Guide
These swim briefs run true to size with a snug athletic fit. If you prefer a slightly looser feel, consider sizing up. Refer to the size chart above for exact waist measurements. Sizes M-XXL accommodate waists from 28" to 36".
Versatile Performance
Whether you are hitting the beach on vacation, swimming laps at the pool, or just soaking up the sun, the Desmiit S312 delivers all-day comfort. The stretch fabric moves with you, the chlorine resistance keeps them looking new, and the quick-dry finish means no soggy shorts on the walk home.
