There's more to seams than just holding your wetsuit together, as the seams are the most likely areas on the suit to:
- Let water in
- Restrict your movement
So, if you're needing maximum flex or are somewhere cold, you'll want to pay attention here.
Flatlock Seams
This method involves laying the edge of one panel over the other and stitching through them both. It creates a durable seam with some flex, but also a lot of holes through the neoprene which can leak. This means flatlock seams are generally reserved for summer wetsuits.
Blindstitch Seams
You'll see blindstitch featured on high-end and winter suits, as it ensures minimal leaking, better flexibility and the best durability out of all the options. It's often listed as Glued Blind-Stitched, or GBS, because the edges of the panels are glued together, end-to-end, before stitching. Then, the stitch only goes part of the way through the neoprene, not fully piercing the panels, resulting in a solid, watertight seam.
Taped Seams
This is where stretchy tape has been applied on the inside of the seams to make them more watertight and durable. It acts as an extra barrier against water getting into your suit. Strategic taping means it has just been applied to the high-stress areas, whereas fully taped means every seam has been reinforced.
Sealed Seams
Liquid rubber is poured over the seams to full waterproof them, on some suits this is done on both the inside and outside of the seams. You'll also see it referred to as 'liquid sealed', 'fluid sealed' or 'welded'.
