There’re different types of seam construction used for wetsuits, as the seams have their own features and function. It’s an important part of learning how to buy a wetsuit. The different types are:
This method is to lay the edge of one panel over the other one and stitching go through them. It’s a durable seam with some flex. But, there’re also a lot of holes through the neoprene. Some water may seep in through these seams.
It’s recommended for warm water. So, flatlock seams are generally used for summer wetsuits.
It’s often described as Glued Blind-Stitched or CBS.
The blind stitching is recommended for colder water. Normally it’s used for high-end and winter suits, as it can ensure minimal leaking, better flexibility and best durability when compared to other options. Because the edges of the panels are glued and bonded together end to end before stitching. The stitching only goes part of the way through the neoprene, not fully pierce the panels, which to help prevent seepage.
This is a stretchy tape used on the inside of the seams to make the suits more watertight and durable. It acts as an extra barrier against water getting into your suit. Fully taped means every seam has been reinforced.
It’s also called liquid sealed or welder.
The liquid rubber is poured over the seam to be waterproof. This can be done on both inside and outside of the seams of the suits. Also, it can be only done on inside or outside. It’s recommended for extremely cold water. Very little water if any will seep through these seams.
