Cold water won’t slow you down; neither should your wetsuit. The Thermal Reaction is built for athletes who demand speed, agility, and warmth in equal measure. Engineered with premium Yamamoto neoprene and a mid-weight zirconium jersey lining, the Thermal Reaction delivers fast-drying insulation, exceptional flexibility, and the thermal protection you need to push your limits in frigid conditions.
Designed for total freedom in your stroke, the Thermal Reaction features the unique single-piece shoulder panel; seamless, unrestricted, and built for fluid, natural movement. Ultra-flexible neoprene in the arms eliminates resistance, ensuring pure power through every phase of your swim.
When the water temperature drops, the Thermal Reaction keeps you going, through every chilling training session and cold water plunge at race start. In the right gear, it's easy to conquer the cold.
Maximum warmth
The thermal "zirconium" liner maximizes warmth with wool-like performance that offers more body heat retention, faster drying and a cozy feel. All in all it keeps you warmer in colder water than standard wetsuit jersey lining.
Seamless shoulders
One single piece of 39 cell 1.5mm Yamamoto neoprene dramatically improves flexibility and reduces fatigue throughout your entire stroke. Combined with 1.5mm underarm panels, you'll find no resistance while swimming regardless of whether your arms are up, down or anywhere in between.
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.
Ultra thin arms
Premium, ultra-thin, 1.5mm neoprene in the arms provides flexibility, comfort and speed.
Premium materials
The highest quality, SCS coated, Yamamoto smooth-skin neoprene offers excellent flexibility and durability. Blueseventy pair this with a high quality, thermal zirconium jersey lining in order to maximize warmth without sacrificing your freedom of movement.
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.
