When folded up the HMY Cycling Vest fits easily into a cycling jersey pocket. But thanks to the use of windproof materials, as soon as you pull it on it provides 100% protection against cold winds - perfect for hilly routes, early starts and fickle weather conditions. 
 
While it keeps the wind out, it's also highly breathable, letting sweat out when you're pushing harder on the pedals. The mesh back also helps in this regard, ensuring you don't overheat. It's a super-stretchy mesh too and in combination with the body-hugging fit keeps the vest as flap-free as possible.
 
An ergonomically shaped collar keeps breezes out and the elastic hem gives a sleek and secure fit.
