All seams associated with neoprene should be located in low stress areas.
One of the worse places to put a seam is in the crotch and under the arm pit.
The constant stretch will inevitably weaken the seam and result in leaks.
Another bad albeit too common idea is to stitch a pad on the Knee and
Elbow which when bent can weaken the outer layer of the main part of the Wetsuit.
We are using for our Nemo Wetsuits, Knee and Elbow padding’s from POLY URETHANE
they are heat transferred free of stitching and stretchable and are very strong against abrasion.
Wrist, Ankle & Neck seals are made out of super multi-flex heat reflecting Titanium Neoprene
that has been special treated with a smooth sleek surface to ensure easy wearing.
Therefore the water exchange is minimized thus makes the suit a Superb Thermal Isolated Wetsuit.
