Iteration 4.0 has been refined for even greater speed, with an enhanced racing fit and using 100% recycled fabric. A more generous cutaway at the back and shoulders improves freedom of movement, and shaves off vital grams (44g in size M). The Italian-made open mesh construction combines with a very close fit to rapidly wick sweat away from the skin so you’ll never overheat in the pursuit of your personal best.
The vest’s ergonomic fit and bonded seams eliminate chafing and help reduce aerodynamic drag. In fact, this technical singlet is so light and comfortable, you might find yourself double checking you’re actually wearing a vest. Proven on the elite racing circuit, the Race Vest 4.0 is a marginal gain you’ll barely feel, until you check your watch.
