i dunno how i feel about this. works great. really pulls the water off of you and stops the wind but only on the chest. the arms, back and sides are not gortex. i wore it once and i have about 10+ pulls on the other material (not the gortex). i dont even know how it's possible. it is an undergarment so i dont care what it looks like but i was extremtly surprised so many pulls in the materiel came from 1 use. still does what its supposed to tho. 3 stars.
