It doesn't get more minimal. First we took, the classic Topsider and Gun Deck, form factors and shrunk , them down as small as possible. To make them even more minimal, we made them out of Kangaroo leather: half as thick and 10x as strong as cowhide. Pocket presence is next to nothing. Tech Specs and Leather - Kangaroo is an incredible leather that is not only our thinnest but also one of the strongest we've offered. 10x the strength of cowhide. *please note that kangaroo and any full grain leather will come with scarring, bug bites, stretch marks, fat wrinkles etc.*  Available in your choice of Italian Conceria Walpier Buttero and stitching.
