The Ultimate Crossbody Strap System™ Black X-Pac™ x Closed-Cell Foam Padding x AustriAlpin® Cobra Buckle

Excellent quality but a bit expensive. (Especially when converting to $CDN) That said the buckle they use is expensive on its own so really, you pay for what you get. I have no doubt the strap will last a lifetime and is much more comfortable than most other shoulder straps on the market.
