TRILAM - Which is short for trilaminate, is a thermally bonded laminate fabric which combines an outer layer of Nylon/Lycra¦, an inner layer of fleece and a central windproof membrane. One huge benefit from this material is it's neutrally buoyant property, which eliminates the need for additional weight and frequent Buoyancy adjustments during your dive. This suit is perfect for all tropical diving conditions. It is not recommended for use in chlorinated pools.
I am looking for a large/xl one. The one I have is made my henderson. It seems the size I am looking for is out of stock.
I am surprised that you have never heard of one. They are great for warm water diving which is all we do. I love mine.
