Bronze Shanks start out as high quality, American made gloves. At the MotoStuka studio, they undergo the “treatment”. “Shanked” and finished out with waxed thread, they’re then conditioned with a balm made of locally sourced natural materials. This age-old recipe waterproofs the leather and gives it a distressed rich copper finish. All our dyes are hand mixed by us, so every glove is unique in color and feel, but ALL get more beautiful with every mile!
