Engineered for triathletes who demand top-tier performance, the Blueseventy Reaction Sleeveless Wetsuit delivers ultimate flexibility, comfort, and speed while keeping you cooler in warmer waters. Adapted from the award-winning Reaction full-sleeve suit, this sleeveless version enhances natural body rotation, increases distance per stroke, and provides superior heat regulation—perfect for races in barely wetsuit-legal conditions or for athletes with broader shoulders and arms who prefer unrestricted movement.

Key Features:

Reactive Stretch Technology (RST): Thinner, highly flexible neoprene in the back and shoulders maximizes range of motion and power generation while reducing fatigue.
Strategic Buoyancy Placement: 4–5mm premium Yamamoto neoprene in the chest, core, hips, and upper legs lifts your body position for better glide, reduced drag, and a more efficient swim.
S-Flex Side Panels: Enhanced flexibility for easier entry/exit and a more comfortable, tailored fit.
Quick-Exit Legs: Lower leg panels allow faster transitions out of the suit.
Improved Low-Neck Design: Minimizes chafing and improves comfort during long swims and sighting.
Premium Construction: High-stretch jersey liner and durable Yamamoto neoprene for exceptional feel and longevity.

Whether you're training hard or racing on a hot day, the Reaction Sleeveless gives you the freedom to swim your strongest while maintaining excellent core warmth and flotation. Minimum temperature rating: 58°F / 14.4°C.

Ideal for: Age-group triathletes, open water swimmers, and anyone who values arm freedom, comfort, and performance in warmer water.
