Genesis:The Whites are a bilaminate; I prefer a trilam fabric myself.
I agree. Most bilaminate suits use a nylon exterior fabric with a polyurethane coating on the inside. They work great until the inner coating starts to wear or crack and they are very prone to developing seam leaks that are then very difficult if not impossible to fix. They are less expensive but potentially have the shortest service life of any of the basic dry suit designs. You will get far longer service out of a neoprene suit for similar money.
