What is the difference between flatlock stitching and blind stitching?
At Libra Neoprene, we offer different stitching methods to suit different performance needs:
Flatlock Stitching — The thread passes completely through the neoprene, creating a flat, durable external seam. Allows maximum stretch and gives a stylish "racing stripe" look. Best for warm-water use where water entry is less of a concern. Common in recreational and shorty wetsuits.
Blind Stitching (GBS — Glued Blind Stitch) — The needle does not fully penetrate the neoprene; the seam is glued and then stitched halfway. Provides better water sealing and thermal retention. Recommended for cold-water use and extended sessions. Common in spearfishing, triathlon, and premium full wetsuits.
Zigzag Stitching (also known as "Z-stitch") — A versatile zigzag stitch pattern that is commonly used for binding edges (e.g., armholes, leg openings, and necklines) and attaching zippers. The zigzag pattern allows the seam to stretch with the neoprene while providing a clean, reinforced finish. Key applications include:
-
Edge Binding — Zigzag stitching secures binding tape around the edges of armholes, leg openings, and necklines, preventing fraying and enhancing durability.
-
Zipper Attachment — Zigzag stitching is widely used to attach zippers to wetsuits, as it allows the zipper to flex and move with the neoprene during active use, reducing the risk of seam failure.
-
Reinforcement — Provides extra strength at stress points where additional durability is needed.
At Libra Neoprene, Our team can advise which stitching method or combination best suits your product based on your target use case, water temperatures, and design preferences. For example, a premium spearfishing wetsuit might combine blind stitching for the main seams with zigzag stitching for edge binding and zipper attachment, ensuring both water-tightness and durability.
