I purchased 4 straps in total, one was silicone elite which is of an amazing quality, as it has always been. Two silicone with fabric, which have been very very pleasing surprise, amazingly soft, don’t need any break in period and they look amazing. One was army green tropical style, this one was a bit less quality than the other, at least to my liking. Rubber seems to catch on hair, I would assume it is not FKM rubber, long end doesn’t go easily through the buckle and once it goes through those ribs on the outer edge of the strap make it slide difficulty. Thank you very much and see you on my next purchase.
