Arena Men's Powerskin Thunder Wetsuit

The Arena Powerskin Thunder Men's Wetsuit is designed around what novice open water swimmers and triathletes actually need: a reliable balance of buoyancy, flexibility, thermal protection and comfort that lets you focus on the race rather than your equipment. It covers all the essentials of a high-performing wetsuit without unnecessary complexity, making it a strong starting point for swimmers making their move into open water racing.

Made entirely from Yamamoto #38 neoprene, the Thunder distributes thickness strategically across the suit. A 4mm core provides buoyancy and support where it counts most, 3mm coverage across the upper chest and legs delivers meaningful thermal protection in cooler open water conditions, and 2mm neoprene at the shoulders and arms allows a full, unrestricted range of motion through every stroke. A zero chafe collar with flattened edges and a soft internal lining sits comfortably against the skin for the full race distance, and an improved zipper closure provides a secure, reliable seal. All seams are bonded with waterproof glue and double blind stitched for a completely waterproof, durable finish. Approved for competition by FINA, World Triathlon (ITU), Ironman and USAT.
