GLUED & BLIND SEAMS (GBS)

All of our fullsuits are made with this finishing which is warrant of a best watertightness.
Neoprene panels are glued together, then the seams are blind stitched together with a nylon thread. The needle does not penetratethe neoprene completely. This is the best sewing technique to prevent water entering the wetsuit.

WARM QUICK-DRY LINING

This lining inside the wetsuits adds an extra layer of insulation. It also dries quicker and offers a comfortable, soft, warm and dry feeling when wearing the wetsuit.

All our fullsuits are made with a quick dry lining.
Depending on the wetsuit, the lining is either located from chest to knees or to ankles.
In order to optimize warmth and weight distribution, we use different linings on our wetsuits, according to their patterns and designs.

TAPED SEAMS

Seams are covered with a stretch neoprene tape for a better watertightness and durability of the wetsuit.
All our fullsuits are made with this finishing, except theBIO II range.

WATER DRAINING HOLES

Perforated holes on the neoprene are draining water that could reach the inside of the leg, is order to prevent water retention. This system is very convenient for wind sports such as kitesurf, windsurf or wingfoil. No need for a velcro tape around the ankle anymore!
