open back, closed back or jammer?
- Swell openback (women's) — an open back for free shoulders and an easy range of motion through the stroke.
- Glide closed back (women's) — more fabric through the back for more compression across the torso and core.
- Cove jammer (men's) — waist to just above the knee, compressing the hips and thighs where your kick starts.
what makes a tech suit fast
A tech suit works through compression and surface. Compression holds your body in a tighter, more streamlined shape and keeps muscles from oscillating as you swim. The surface decides how cleanly water moves past you. deboer race suits are made from 3dium, a fabric woven with a hexagonal 3D texture, with bonded seams that lie flat against the skin.
open-water tech suits
For open-water races too warm for a wetsuit, the Peak (men's) and Crest (women's) open-water suits bring race-suit compression to lakes and the sea. Triathletes looking for a swimskin should see the Tsunami 4.0 in warm-water racing.
how a tech suit should fit
Much tighter than a training suit. A new tech suit can take 10 to 15 minutes to put on — work it up a little at a time with your fingertips, never your nails. Use the size chart, and the fit guide if you are between sizes.
frequently asked questions
are deboer race suits World Aquatics approved?+
Yes. Our pool race suits are World Aquatics approved, so they are legal for sanctioned competition.
how tight should a tech suit be?+
Tight enough that it is hard work to put on and feels restrictive on land. In the water it should hold you firmly without cutting in at the shoulders or legs, and without gaps or wrinkles where water can collect.
how do I make a tech suit last?+
Save it for tapered swims and competitions, not training. Rinse it in cool fresh water after every use and let it dry flat in the shade. Keep it away from rough pool edges and sunscreen.
what is the difference between a tech suit and a training suit?+
A tech suit is built for speed over a few races; a training suit is built to survive daily chlorine. For everyday sessions, see training swimwear.
