Built to help us conquer the cold waters of early-season racing, the Blueseventy Thermal Reaction Fullsuit is redesigned to promote more natural body rotation, increase our distance per stroke, and keep us warmer so we can do our best. 5mm thick panels of durable 39-cell Yamamoto neoprene are placed on the core and hips for optimal buoyancy and taper down to 1. 5mm on the shoulders, lower legs, and arms for maximum freedom of movement. A Zirconium jersey liner helps further protect us from the cold waters with its wool-like properties and exceptional heat retention, while a redesigned neck ensures chafing doesn't ruin our race.
