O'Neill
The most popular method of sewn construction. The stitch uses 4 needles and 6 threads, and works by overlapping the neoprene panels and sewing them together. It is a strong stitch and is very comfortable because it is flat, but it is not a sealed seam so it is not intended for extremely cold conditions.
An ergonomic, seamless under sleeve panel that allows for unrestricted motion and eliminates rashing. Flexible and unique design which utilizes minimal seam placement for comfort.
