Conquer the Cold

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 our 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.

Neoprene Buoyancy & Flexibility

When it comes to a swimming wetsuit, two factors really matter: Flexibility and Buoyancy. Thinner neoprene is more flexible, while thicker neoprene will provide more buoyancy.

Blueseventy wetsuits are strategically designed to offer the most flexibility where you need it, such as the arms, shoulders and upper back area. We use thin, 1.5mm - 2mm neoprene in these areas to offer complete freedom of movement throughout your entire stroke.

Thicker neoprene is placed in areas that typically tend to sink for swimmers, and where flexibility is not key. You'll find 4mm - 5mm neoprene in the chest, hips, and upper legs to enhance your swim form to be as efficient and streamlined as possible.

  • 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, we've 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. We 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.
  • Minimum Temperature 48 degrees F
