I purchased a Alpinestars Track Vest Size M for my track day. But turns out it fit too loose on me, and was not a good fit under my 1 piece suit. I wore it for ONE run - 4 laps. So basically its still in mint condition. Did not crash or anything. It would be a great compliment for wearing under a jacket. It is made of stretchy nylon like material and offers padding for the chest, kidneys, shoulder blades, and of course the CE level 2 back protector. The back protector actually can be zipped off, so you can wash the mesh vest itself.

I have a build of: 5'5" 160lbs, 30" waist, and 38" chest. Again it fits loose on me, so if for an ideal fit, you should be 2-4" larger in the waist and chest than me and it should be fine because of the stretchy material.

Retails for: $190. Looking to get $175 shipped anywhere to lower 48. OBO.
