Issac Miller’s Signature Hella Grip griptape, iShackDenim, is now available. Though it’s not actually made from real denim, the quality of the jean print will have you fooled into thinking you can sew a Canadian tuxedo out of these sheets. The “Issac Miller” stitching on the pocket definitely adds a touch of fashion couture. iShackDenim is printed on white (Formula-W) sheets of Hella Grip (6 x 24). Each sheet has the same gritty texture as Hella Grip’s classic sheets.
