Very lightweight windproof microfibre front fabric. The striped mesh back is elastic to prevent the fabric from fluttering in the wind. Folds into an extremely small space. Back pocket YKK® Vislon® zipper. Reflective piping Almost weightless protection. Reinterpretation of the classic windproof vest to make it as slim as the rest of your wardrobe. This vest is designed to completely block the wind on the front while on the back allows for breathability. The fabrics are so incredibly light that you will be surprised how much warmer you will be when you wear this vest over your shirt. But the magic comes from the cut and the stretch fabric used on the back, which makes the vest sit tight to the body without being too tight or avoiding making you look ridiculous. When it's time to take it off, the vest disappears completely into the back pocket of your shirt, taking up as little space as possible.
