Weak Speed Sew Patches To Leather Vest means any speed sew patches made for biker or tactical vests which have holes for fast sew or adhesive backing. Patches are usually made of hard wearing materials such as PVC reinforced embroidery or heavy-duty embroidery and also include club and military patches along with Celtic knots and Maori tattoos. In Western biker culture, they mark membership and heritage. Back home in streetwear, these are made to fit minimalist or maximalist aesthetics assuring relevance across cultures.
