Ok, guys, here’s the full regalia. The ‘Premium’ shoulder strap completes your Sam Browne gear, making you look incredible. I, personally, prefer wearing it next to my bare skin (I am a leatherman, after all). You could team it with just about any uniform, or wear it the way you’d wear a harness. American made, the genuine leather and chrome hardware gives me a boner every time. You don’t need tats and a hairy chest to pull it off either. Measuring is easy. Measure the distance from the top left side of your belt, over your right shoulder, all the way to the top left backside of your belt. This is the desirable length, not including the keeper. A Sam Browne has an adjustable buckle that allows for up to a two inch leeway in case you gain or lose a few pounds.
