Rosti® and SANTA CRUZ® come together in the strength of experience and the ability to imagine the future. The synergy with the Rosti® world is direct because today projects of connection to nature and the ability to create new viable paths count. SANTA CRUZ®, like Rosti, is a way of being. SANTA CRUZ®, one of today's most iconic sports brands, is simplicity of vision and pure legend. SANTA CRUZ® FSA® shorts are what happens when the best available technologies are used in technical sportswear. The SANTA CRUZ® FSA® shorts are PRO1, an ergonomic Thunderbike® fabric which means 80% polyamide and 20% elastane. Thunderbike fabric is a rubbery polymer and more precisely a fabric composed of high density bonds that reinforce its structure. Raw cut with internal silicone at the bottom of the leg. With perforated and two-tone straps. The Airgap® chamois is made entirely from recycled yarns. Suitable for medium distances thanks to the construction of the surface fabric assembled with a structured perforated foam that allows quick drying. The high impact foam with progressive cut makes a comfortable and uniform seat.
