Product Description

The Men’s Blueseventy Reaction Wetsuit is packed with design features that effectively work to help you swim better. It’s super flexible, very forgiving in terms of fit, it’s warm and we think it’s worth every penny.

Exceptional fit and reach
Made from the best Yamamoto neoprene available which allows a more natural swimming movement. The addition of thinner side panels and ultra-stretchy components dramatically improves the fit and flexibility of the suit. The lower neckline increases comfort and reduces chaffing without compromising the seal.

Great fit and less chest restriction

The Reaction has a 2mm central split chest panel to allow greater chest expansion and unimpeded breathing. This coupled with the thin 2mm side panels that begin at the arm gussets and end at the knee ensures a close, flexible fit around the torso.

Great position in the water

The Reaction tiers buoyancy 4-5-4 by centralizing core buoyancy to raise the position of the hips in relation to the rest of the swimmer. Two chest panels of 4mm accentuate natural lung buoyancy to optimize the 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.

Less drag and more warmth

The slippery SCS coating, along with great body position reduces drag. The Reaction fits like a second skin so water cannot flush through the suit keeping you warmer and reducing drag. 4-way stretch fabric used in the silicone cuffs (Aquaseal) also helps by sealing the wrists from water entry.

Get out of your suit quicker

If you are a triathlete or just someone who struggles to get out of your wetsuit, you’ll appreciate the lower leg panel. This is only 2mm thick which promotes a quick escape from your suit. The internal seam is taped so you can trim the leg to a shorter length if necessary.

Blueseventy Reaction Wetsuit Features:

  • Super soft and comfortable
  • Warm without being restrictive
  • Optimises body position (in a nice way) 4-5-4 design
  • Swim faster in more comfort
  • 2mm Behind the knee panels for extra comfort when walking, running, and swimming
  • Textured forearm S-Grip provides an excellent feel for the water
  • The choice of most of our Swim the Lakes Swim Guides


The Blueseventy Reaction is, in our opinion, one of the best wetsuits for open water swimming available if you want a natural feeling suit with amazing flexibility, to be warm and comfortable then, without doubt, this is the BlueSeventy Reaction is for you.

    Just to let you know that kit purchased from your kind self is working extremely well. The ‘reaction’ suit in size medium has also been great. I would have gone for the ML if had not been for your guidance so much appreciated. All the best.
