These great mouthpiece holsters utilize our famous Loredo Leather, 3-8 times thicker than the competition. Shown here against the competitor Protec leather, you can see the difference: Protec is the black leather (Ha! They call that leather?!?! Yeah, from a malnourished squirrel.), and is as thin as our lining fabric underneath our thick-as-a-horse-shoe brown leather. Torpedo Bag Mouthpiece Holsters offer far greater protection and are much classier than the competition. Only our guys have the equipment to sew this stuff, here in the USA.
