All BKS seams have been tested to ensure they are correctly used according to their strength and location within the garment. Only some seam types are strong enough for high risk areas. BKS has a portfolio of 17 seam styles but the main ones used for garment construction are the most important.
Thread needs to be a certain thickness and have some elasticity. Kevlar thread, whilst strong, has a tendency to snap in areas where constant folding occurs and so is not used in any BKS suit. Suit making thread is Gauge No. 20 Nylon bonded and is available in 12 shades to complement the colours of your suit.
All main panel construction uses seams with buried stitching of multiple rows with additional topstitching to keep seams flat and secure.
