The bag was made from gray Sunbrella with black mesh inserts made of Serge Ferari Stamoid mesh (and isn't that material expensive...).
The bag is stitched with Tenara thread made by Gore (of Goretex fame) in the USA. The thread will certainly outlast the fabric, as we proved with the last main sail bag, where the fabric eventually disintegrated but every seam held.
Our sails are also stitched with Tenara, which we believe has a potential life of 25 years - if only the fabrics could last that long.
Thanks to Royal Cape Yacht Club for providing a great working space for us - most of the job was cut and sewn in the Regatta Function Room at RCYC.
