These custom dyed training belts by Pioneer are hand dyed using a professional dye in house. They are treated with a conditioner, polish, and sealant to maximize sheen and longevity. They are built using the same 100% Vegetable Tanned Sole Leather that we use on all of our belts. These are what I call the “Sophisticated Belt” on our social media outlets and are an awesome contrast to the embroidered custom belts that we offer. If you are looking for an old school- no frills belt that will last you a lifetime, this is the one for you! The Training Belt version of the Custom Dyed Belts are 4in in the back and taper to 2.5in on the sides and front.
