Bust out your bike, zip into the Sugoi Men's Helium Vest, wrap your feet in plastic shopping bags, and tell the storm that showed up just in time for your commute to go to hell. This lightweight semi-fitted vest features wind- and water-resistant fabric on the front and breathable mesh fabric on the mid- and lower backAAAall in a super lightweight package. The Helium VestAAAs front fabric stops the wind and drizzle from robbing your warmth from your core while you pedal or run. The back fabric features a mini-triangle hole pattern that vents heat, yet doesn't sacrifice coverage. A back pocket holds your MP3 or keys, and 3M Scotchlite along the front zipper helps drivers see you in low light conditions.
