These sails made by Elvstrom Denmark. I ordered them via Elvstrom La Rochelle after a recommendation from a French A54 owner who already have for a few years and is very happy with them.
Sail type EMS Max EPEX Double Taffeta with Carbon / Technora fibers in between. Check out their website for further explanation about EPEX
The sails are made from old PET bottles so very eco friendly. They have a superb cut the only thing I found sorry is that they are not real white.
