Had an XL for over 5 years and the only wear and tear is on the strap on the underside,
brilliant bag it's only downside is you will put too much stuff in it mine weighs around 26kg+ loaded but that's because I've recently been doing a lot of mechanical work hence spanners etc plus normal electrical gear
Re the hammer a claw hammer will go in upright in front of the pockets also you can fit long drivers in just!
I bought a continental type hammer from Germany recently as it's slightly smaller, which is better for the zips!
I'm thinking about getting
the MC bag as I go overseas every few months to do installs and I only take the most used items , i bought a couple of smaller bags made by Stanley and dewalt which didn't last more than two trips, plus I like tools to be organised and accessible instead of just chucked in!
Does anyone have one????
If so could you post your thoughts?
