Aerofit Cut and fabrics are studied in every cm2 to minimize aerodynamic friction. 2 Way Breathable Fabrics designed for maximum ventilation and heat dissipation. ultralight Use of ultralight materials: you won't even feel it. Racefit Race fit, narrow waist and elastic compression for maximum performance.

All cyclists know how much difference what you wear can make. It focuses on the detail, the fabric, its stitching, and as Dave Brailsford’s Marginal Gains theory teaches, multiple small improvements, singularly negligible, give rise to significant progress. Hardskin’s R&D department has created an aerodynamically effective and performing garment. The result is surprising and exclusive, for those who seek the maximum in performance without compromise.

The body AEROSUIT TT LS, result of research and studies in the Wind Tunnel. It is made with the aerodynamic and wrinkled Aero Stripes (AS) fabrics in the arms, legs and shoulders, while the front and rear parts are in Speed Fabric (SF), a type of heat-treated and silky fabric, designed for aerodynamic efficiency and higher performance

The Aero Crono cut, with no back pockets and long sleeves, gives the body the ultimate in aerodynamics.

The shorts in Elastic Gradual Compression (EGC), the special fabric to support the muscles of the hardskinner in race position, and the outer back and breathable Vapor pad complete the body offering the right comfort, the vibration absorption and breathability you’ve always been looking for. Just because ultra-tight, it is recommended to buy a size more than usual. As a gift, Hardskin’s aerodynamic sock is combined with the bodysuit. You are now ready to cross the finish line in record time.

Our products have positively passed the Wind Tunnel tests in comparison with the main top of the range long-sleeved leotards of our competitors.
The graph shows that of all the long-sleeved products tested, the Strouhal AEROSUIT TT LS is 2.5 to over 4.5% more efficient and aerodynamic, and the Von Kármán AEROSUIT TRI SS short-sleeved triathlon leotard is aerodynamically more efficient than nearly all the competitors' long-sleeved leotards considered.

AS: The Fabric Aero Stripes is designed for the fastest race conditions. Wrinkled and able to create an effect similar to the dimples on the golf ball, it acts directly on the boundary layer and the air is able to remain attached to the surface much longer, creating a narrower trail downstream and thus reducing drag, that is the aerodynamic losses, clearly improving the aerodynamics of the athlete.

SF: The Speed Fabic fabric is designed to perfect the aerodynamic properties of some yarns.
It mechanically influences the texture of the fabric making it more compact and smooth surface, similar to a silk effect. Higher speed for a material that leaves the moisture absorption capacity unaltered.

VP: Vapor Pad VP is the technology that allows us to have shorts so highly performing.
We have chosen to differentiate ourselves and to subvert every rule, researching, studying, testing and giving life to a unique technology in the field. We specialize in performance study, millimeter fit, perfect adjustments and marginal gain. Vapor Pad VP technology is the result of this research method that has allowed us a product as light as steam, but with a unique damping effect in the industry.

Washing&care Wash at 30° and without bleach: do not use iron and do not dry clean! Look closely at the label of each garment. By following the washing instructions, make sure your Hardskin product works as smoothly and for as long as possible.
Additional Information All Hardskin products are designed and developed for those who do sports and those who do sports and are the result of a mix of skills and experiences. On the one hand science and performance with fabrics, cuts, seams that are the result of research and studies of our engineers in the Wind Tunnel. On the other Jonny Mole, the design touch behind Hardskin. A winning project always brings with it an intuition. That’s why Hardskin has intuited an opportunity and translated it into an understanding: the one with Jonny Mole, for over 20 years has signed design and sports communication in Italy and around the world. Cittadella’s studio (PD) created the garments for the race and casual collection, doing justice to the brand’s contemporary spirit through a surprising balance of performance and fashion.
