Blind stitching is a sewing technique whereby the needle never completely pierces the material, meaning that water cannot wick along the threads to the inside of the suit, because the threads never actually make it inside the suit. Gluing the seam prior to sewing makes the seam totally waterproof. Double blind stitching means that the suit is sewn once on the inside and once on the outside for double strength.
Gluing twice and double blind stitching ensures that Pinnacle’s seams are the strongest and driest that there are. To go a step farther, Pinnacle places a stress disk on each seam intersection, which not only makes the suit stronger still, but also makes it more comfortable.
Pinnacle Aquatics employs double gluing and blind stitching and the application of stress disks on all but our lightest weight suits. This is a very time-consuming and expensive way to go. Many manufacturers use flatlock stitching on most suits (particularly on 3mm suits) because is it less expensive and easier. If you want the best made suits, you’ll choose Pinnacle.
