In a rubber wetsuit this does not paintings nicely for some of motives, the principle one being that punching holes directly through each layers of foam for the thread opens up passages for water to waft inside and out of the match. The 2nd problem is that the stretching of the foam tended to amplify the needle holes whilst the fit turned into worn. This intended that a wetsuit will be very bloodless all alongside the seams of the in shape. And although the sewn area did keep the two portions collectively, it could additionally act as a perforated tear facet, making the fit less difficult to rip along the seams while placing it on and taking it off.
