Description
unleash your speed with deboer's groundbreaking glide openback swim suit featuring our exclusive 3dium technology.
Engineered for the relentless pursuit of performance, deboer's new line of technical race suits featuring the revolutionary 3dium fabric are set to redefine the boundaries of speed in the water. Crafted with a unique 3D weaving technology that utilizes a hexagonal texture, these suits are designed to propel you to uncharted levels of hydrodynamic efficiency.
Our 3dium fabric is a true game-changer, meticulously engineered to reduce drag and maximize your power with every stroke. Its innovative hexagonal structure creates a turbulent boundary layer that mimics the hydrodynamic properties of shark skin, allowing you to slice through the water with an ease previously unattainable.
But speed is just the beginning. deboer's commitment to innovation ensures that these suits provide uncompromising comfort and flexibility. The 3dium fabric's unique weave molds to your body like a second skin, enabling unrestricted range of motion and optimal muscle compression. This seamless fusion of compression and flexibility enhances blood flow, minimizing fatigue and empowering you to sustain your peak performance from start to finish, regardless of distance or stroke.
Developed over nearly two years of rigorous testing at the state-of-the-art T3 Tenerife swim flume, the 3dium race suit represents the pinnacle of deboer's pursuit of a faster tech suit. Whether you're a sprinter, distance specialist, or medley swimmer, the 3dium suit is engineered to help you conquer the pool while going #FASTER than ever before.

a tech suit is meant to feel tight.
race compression should take real effort to get into and hold you firmly through the catch. if it's comfortable to pull on, it's too big to be fast.
