Product Details

Blueseventy Reaction Wetsuit

Inspired by the Helix wetsuit, the Blueseventy Reaction Wetsuit has a redesigned upper-body panelling that promotes a more natural rotation, helping you cover more distance with every stroke. The lower neckline reduces chafing while maintaining a watertight seal, ensuring comfort without compromise. With 1.5mm Yamamoto neoprene in the arms and underarms, resistance is virtually eliminated, whether your arms are extended, recovering, or mid-stroke. The result? A suit that moves with you, not against you.

Flexibility Meets Power: Built for Efficiency

The Reaction’s 2mm high-stretch neoprene in the shoulders and back reduces fatigue, while the 5mm core and 4mm lower legs optimise buoyancy for a streamlined, hydrodynamic position. The narrowed centre panel and thinner side panels encourage a powerful, rotational stroke, translating to more speed with less effort. Plus, 3mm leg panels ensure a snug fit for all body types, and the 1.5mm leg panels make quick transitions a breeze.

Durability and Customisation for Serious Athletes

Crafted with SCS-coated Yamamoto neoprene, the Reaction offers unrivalled flexibility and durability, so your suit performs as hard as you do. The reinforced seam taping even allows for leg trimming, letting you tailor the fit to your preference. Whether you’re logging training miles or racing for the podium, this wetsuit is designed to elevate your swim.

Note: Avoid using your fingernails when putting on your wetsuit. Nails can easily cut the neoprene and leave small crescent-shaped cuts, leading to larger holes. Rips or tears due to lack of care are not covered by warranty, so please take extra care and follow the instructions enclosed with the product to prevent damage from happening.

  • One single piece of 39-cell 1.5mm Yamamoto neoprene dramatically improves flexibility and reduces fatigue throughout the entire swim stroke

Chris H,
Verified purchaser

Saw suit on Sigma website at a very competitive price, bought and it was delivered quickly, very well packaged too. I've had many Blue Seventy suits before including Helix's and Reaction. This suit fits perfectly and is extremely felexible, more so than my older Reaction and almost on a par with my Helix. It provides additional bouyancy where needed, extremely easy to get on and off and easy to zip into too. I do prefer the older blue/orange "Blue 70" styling over the new red/silver but that is just personal taste. For open water swimming, my new Blue Seventy Reaction suit is superb.
