Blueseventy Thermal Reaction Fullsuit Wetsuit – Women's

High-Performance Cold-Water Wetsuit for Maximum Warmth, Flexibility and Speed

The Blueseventy Thermal Reaction Fullsuit Wetsuit is designed for triathletes and open-water swimmers who need extra warmth without sacrificing performance. Mirroring the advanced paneling of the Reaction wetsuit, the Thermal Reaction encourages natural body rotation, enhances stroke efficiency and provides superior insulation for cold-water conditions.

Ideal for colder open-water training, early-season races or athletes searching for wetsuit hire near me, the Thermal Reaction is also a perfect choice for those exploring triathlon wetsuit hire or rental before investing in a premium cold-water suit.

Why Choose the Blueseventy Thermal Reaction Wetsuit?

Maximum Warmth

A thermal “zirconium” lining mimics wool-like performance, retaining more body heat, drying faster and keeping you cozy in colder water than standard wetsuit linings.

Seamless Shoulders for Freedom of Movement

A single-piece 39 cell 1.5 mm Yamamoto neoprene shoulder panel provides full flexibility and reduces fatigue, while 1.5 mm underarm panels allow unrestricted movement throughout the entire stroke.

Optimised Buoyancy

5 mm core and hip panels transition to 4 mm in the lower legs, lifting the body into a streamlined position to reduce drag and improve efficiency.

Natural Rotation Hip Drive

Extended 3 mm side panels through the hips improve natural body rotation, generating more power with less effort and maximizing stroke distance, inspired by the Helix design.

Reactive Stretch Technology

2 mm neoprene with high-stretch thermal jersey enhances mobility and reach across the shoulders and back, reducing fatigue and improving stroke efficiency in cold water.

Ultra-Thin Arm Panels

1.5 mm neoprene arms deliver flexibility, comfort and speed while maintaining warmth.

Premium Materials and Construction

Constructed from SCS-coated Yamamoto smoothskin neoprene paired with thermal zirconium jersey lining, the suit maximises warmth without limiting movement. Durable, flexible and hydrodynamic, it is engineered for performance in colder conditions.

S-Flex Side Panels and Quick Fit

3 mm side panels on the legs improve fit across different body shapes and make it easier to get into the wetsuit, ensuring comfort and efficiency from start to finish.
