I have 3 pairs of 5.11 trousers 

Two pairs are the ones with '5.11 Tactical' in the waistband

One pair with '5.11 Tactical Series' in the waistband

There's hardly any difference between them other than the stitching for the knees (you'll spot the difference in the photos)

I've had all three pairs professionally altered to fit a 34" waist and a 30" inside leg (I'm a short-ass) and it cost me a damn fortune because of the work involved (anyone who's owned a pair of 5.11s will know they have a very baggy ass and the leg is very long as standard

Bought them brand new and paid for the alteration so each pair probably ended up costing me the best part of £100

I'm asking for £50 each.  They're in excellent condition, only used for work, not for training or exercises.
