Engineered for athletes who demand top-tier performance, the Reaction Sleeveless Wetsuit delivers ultimate flexibility and comfort, while keeping you cooler in warmer waters. Adapted from the redesigned Reaction wetsuit, this sleeveless wetsuit enhances natural body rotation, increases distance per stroke, and provides optimal heat regulation, ensuring your core temperature stays lower in warmer water.
You're either reaching for the Reaction Sleeveless because you're swimming in water that’s barely wetsuit legal, or because your arms are larger and you find a full-sleeve suit too constrictive. Either way, this wetsuit is designed to provide peak performance through all your training and racing swims.
Easier breathing
An improved, lower neckline increases comfort and minimizes chafing without compromising the seal to prevent water entry.
Sleeveles core cooling
When water temperatures are warmer (think above 21°C) a sleeveless suit can help regulate your core body temperature keeping you cooler during the swim. A small sacrifice in speed can be a winning tactic as you head out of the water with a lower core temperature, ready for a hot bike and run.
Optimized buoyancy
5mm thick core and hips transitions down to 4mm in the lower legs to maximize your efficiency with a more streamlined body position.
Natural rotation hip drive
Building off the Helix design, blueseventy narrowed the center panel on the upper body and extended the thinner, 3mm, side panels through the hips to maximize your natural body rotation in order to generate more power, resulting in more speed with less effort.
Reactive Stretch Technology
2mm neoprene with high stretch jersey offers greater mobility and reach throughout the shoulders and back, reducing fatigue and increasing distance per stroke.
Premium materials
The highest quality, SCS coated, Yamamoto smooth-skin neoprene offers excellent flexibility and durability. Blueseventy pair this with high quality, extremely stretchy jersey linings in order to produce an end result that never limits your movements while swimming.
S-Flex side panels
3mm side panels on the legs help create an optimal fit across varying body shapes and improve the ease of getting into the suit.
Quick exit legs
1.5mm thin leg panels make it easy to get out of the suit after your swim, decreasing your transition times. Reinforced seam taping allows you to trim the legs if needed.
