2026 Men's Reaction Full Sleeve Wetsuit

The Men's Blueseventy Reaction Wetsuit (often stylized as Blue70 or Blue Seventy) is a premium triathlon wetsuit designed for swimmers and triathletes seeking exceptional flexibility, buoyancy, and speed in open water.

This high-performance full-suit features ultra-flexible, thin neoprene in the arms and shoulders for unrestricted range of motion and effortless stroking. Premium Yamamoto neoprene (including air-cell construction in the core) delivers superior buoyancy to lift your hips and improve body position, while targeted paneling enhances natural rotation and power output. Additional highlights include S-Flex side panels for easy on/off and a comfortable fit, textured S-Grip forearms for better catch, a low-profile neckline to reduce chafing, and seamless shoulder design inspired by elite-level models like the Helix.

Ideal for training and racing in moderate conditions, the Reaction strikes an outstanding balance of comfort, speed, and value—making it a bestseller for athletes who want pro-level performance without the pro-level price.
