amazing feeling

5` 11"

Hard to describe how this feels, but it feels like a mix between the proton LT and a fleece. the inside is the same stuff the Rush IS has, but its closed in with some kind of liner that feels amazing. Basically like a Proton LT in structure, but composed of different materials. i'm 5'11 175, muscular upper, the Large fits perfect (its not loose, quite form fitting)
