In reply to PaulTanton:
I used to be a big fan of the Axiom Jeans, but stopped using them as a result of how quickly they wore out.
In recent years I've favoured anything which features Cordura, as they seen to be infinitely more durable. Of those I've used the Alpkit Jeanius and/or Sequence are probably the best, and most reasonably priced. The Black Diamond Hot Forge Demin were also good, but had pretty poor quality stitching in/around the pockets, meaning that whilst the rest of them were in perfect conditions - the pockets had all but fallen apart.
Apologies for the unsolicited advice, but I reckon once you try the cordura based denim you'll never go back - it's leagues apart in terms of quality/durability.
