The reception for blueseventy's original thermal suit far exceeded their expectations. blueseventy immediately heard from a growing market of eager open water swimmers who praised them for extending their outdoor swimming season. The THERMAL Reaction is their response to deliver this option to more swimmers.

Built with a high-grade traditional YKK zipper for easy in and out, proven RST panels, SCS coating, triple glued seams, blind stitched and internally taped high stress areas - the only thing left to do is hook your key on the loop and jump in.

MADE FOR COLD WATER

Full internal zirconium jersey reduces water absorption and protects against heat loss. Paired with neoprene accessories the THERMAL Reaction is rated down to 48°F / 9°C while a standard full suit for swimming is typically good to 54°F / 12°C. 

VO2 CHEST PANEL

A central split chest panel allows greater chest expansion and unimpeded breathing. 

REACTIVE STRETCH TECHNOLOGY (RST)

Upgraded to silver premium Yamamoto #39 cell rubber, the RST panels improve arm mobility, reach and propulsion. 

S-FLEX

2mm thin side panels improve fit and body rotation in the water without sacrificing buoyancy.

BUOYANCY +

The THERMAL Reaction features a 4-5-4 panel design centralizing core buoyancy to raise the position of the hips in relation to the rest of the body. Two 4mm chest panels accent natural lung buoyancy to optimize upper body position relative to the legs. 5mm neoprene supports the hips and lower torso, lifting the body in the water, reducing drag and improving speed. 4mm panels in the lower legs ensure a more efficient kick by keeping the legs on the surface of the water.
