This 55g featherlight and packable vest protects you against wind. A must have which now features lots of reflective highlights. The vest is like the multitool of cycling apparel. Wear it over a short or long sleeve jersey; use it as a midlayer or an outer layer depending on temps and conditions. Keep it stashed in your jersey pocket and know you're rolling with 55 grams of feather-light premium protection from the elements. Like a finely-tuned comforter for your core, the Cosmic Wind Vest helps riders retain essential heat, deflect wind and shed light precipitation. A new, exclusive stretch nylon fabric maintains the vest's ultra light weight and packability, while the fabric's ripstop texture bolsters durability to provide years of use. A slim fit, elastic waist and cuffs minimize flapping in the wind like a wayward sail while keeping body heat where you need it most, but doesn't impact range of motion due to ample stretch in the fabric. To maximize breathability, Mavic incorporated a mesh panel in the back and lateral laser holes to evacuate sweat and optimize climate control. Its slim fit keeps bulk to a minimum and high-end zips and nylon material denote Mavic's strong attention to detail and dedication to high-performance products. Reflective branding elements sparkle in the sun and add visibility in low-light and stormy conditions.
