The Tosa 1-pc. Leather Suit is made of premium perforated Tutu cowhide for optimized temperature control on hot days. Slim and fitted design provides excellent freedom of movement thanks to the S1 elastic fabric inserts on the inner arm, groin, and back leg areas. The biaxial stretch fabric inserts on the back, as well as the stretch patches on the knees and shoulder blades, are designed to protect the skin, while maximizing flexibility and movement. The special protection system combines Dainese's classic internal protectors with removable sliders on the knees and interchangeable aluminum plates on the shoulders. A distinctive Dainese technology designed to support and facilitate sliding in case of a fall, preventing the dangerous risks of rolling caused by grip on asphalt. The aerodynamic hump is designed to accommodate the water bag, allowing you to connect to the helmet. The hump is placed at the shoulders and neck to protect the upper back, complementing the back protector.
