Based on our Lanthana classic set-up and shape, we made the Lanthana Vintage using veg-tanned bovine splits, with a "retro" pull-up finishing, thickness is around 2,8mm. That strap is gonna get some beautiful patina while being used. It will age the right way along with your guitar. Various length adjustment options. Width on shoulder : 9cm as you bass' weight will be more equally distributed.
