Sugoi Helium Jacket - Men's - $39.98

The Sugoi Men's Helium Jacket isn't really lighter than air, but it does weigh in at a mere three ounces and protects you from light rain and wind. This semi-fitted, breathable jacket features laser vents under the arms so you don't get swampy feeling as you run. A back pocket holds your MP3 or energy gel, and 3M Scotchlite along the zipper helps vehicle drivers see you in low light. - $39.98
