I bought the slightly smaller Tech LC version 6 years ago. I bought through these people who are UK distributors, but there are other stockists around:

The way it’s worn so far, I would expect it to last at least another 6. The only issue I’ve had is with the detachable shoulder strap which wore out after 18 months, but they sent me an improved one free of charge under the 5 year warranty.
