Wetsuit Seam Technology Flatlock vs Glued & Blindstitched Leaks

Introduction:

When it comes to choosing the perfect wetsuit, one of the most crucial factors to consider is the seam technology used. Wetsuits are designed to keep water out and provide warmth to the wearer, but the effectiveness of this depends heavily on the seam technology employed. In this article, we will delve into two popular seam technologies: flatlock and glued & blindstitched, and discuss how they impact the likelihood of leaks.

Wetsuit Seam Technology Flatlock vs Glued & Blindstitched Leaks

Flatlock Seam Technology:

Flatlock stitching is a method of joining two pieces of fabric together using a zigzag stitch that overlaps the edges. This technique creates a flat, comfortable seam that is less likely to chafe or irritate the skin. The overlapping edges of the fabric help to prevent water from seeping through the seam.

Advantages of Flatlock Seams:

1. Comfort: Flatlock seams are less likely to cause chafing or irritation, making them ideal for long-duration activities.

2. Durability: The overlapping edges of the fabric provide added strength and durability, reducing the risk of seam separation.

3. Breathability: Flatlock seams allow for better airflow, which can help to regulate body temperature and prevent overheating.

Disadvantages of Flatlock Seams:

1. Water Resistance: While flatlock seams are effective at preventing water entry, they are not as water-resistant as glued & blindstitched seams.

2. Cost: Flatlock seams may be more expensive to produce due to the additional material required for the overlapping edges.

Glued & Blindstitched Seam Technology:

Glued & blindstitched seams involve applying a waterproof adhesive to the edges of the fabric before stitching them together. The blindstitch technique ensures that the stitching does not protrude on the outside of the wetsuit, creating a smooth, seamless appearance. This method is known for its exceptional water resistance and durability.

Advantages of Glued & Blindstitched Seams:

1. Water Resistance: Glued & blindstitched seams offer the highest level of water resistance, making them ideal for cold water conditions.

2. Durability: The combination of glue and stitching creates a strong bond that is less likely to fail over time.

3. Aesthetics: The blindstitch technique provides a clean, professional appearance that is favored by many wetsuit manufacturers.

Disadvantages of Glued & Blindstitched Seams:

1. Comfort: The stitching may be slightly more noticeable than flatlock seams, which could cause some discomfort for some wearers.

2. Cost: Glued & blindstitched seams are generally more expensive to produce, which can affect the overall cost of the wetsuit.

Conclusion:

Both flatlock and glued & blindstitched seam technologies have their advantages and disadvantages. When choosing a wetsuit, it is essential to consider the intended use, water temperature, and personal preferences. For warm water conditions or activities with shorter durations, a flatlock seam may be sufficient. However, for cold water conditions or extended periods in the water, a glued & blindstitched seam is the preferred choice due to its superior water resistance and durability.
