So, what is it? I ask because I'm curious, and I want a new one. I have a decent Tamrack neck strap that I use as a shoulder strap, but I'm tired of it sliding all over the place when I wear leather or something. I was thinking of an UpStrap, but I don't know. I just want something that I can sling on my shoulder that won't slide off. So, what is your preferred strap? How do you "wear" it?
