Gray side texture has these hexagonal bumps, and it is not abrasive at all; soft and flush, and the other side feels even cleaner. Which brings me to the point of... there is noisy, almost psychedelic colourful side of the jacket - and more low-profile gray side. The choice to choose which side to wear - or change, in middle of an outing - makes this piece of clothing quite a unique purchase I have made in some time.
My only slight nitpick would be that the wristbands feel little rough/worn on the fabric after few weeks of wear, but I reckon washing it may fix that, or taking care of it some other way. I'd have to do my research to find out what the options are on getting it back to feel pristine, but otherwise, I have no complaints of the jacket - and it is well worth the price.
(As I write this review, I have already made few more purchases on this website, rip wallet)
