I've bought two pairs for my boyfriend, he is tall so the custom inseam is a nice touch if you have the time to wait for them to ship. I'd say its worth it, but definitely a factor to consider.
Overall he loves them, the fabric is resilient and the double front adds an extra layer of protection, so they stay intact while other pants will develop holes from general wear and tear. After a few washes they still look nice, you can see how the dye wears off a bit but they have worn well and have a lot of reinforcement where it would matter, they seem like they are quite durable.
The improvements I could recommend are the amount of pockets- which could be a good thing but there are a few pockets that are too long and narrow for him to reach into, so he has to remember not to use those ones because it take some effort to retrieve something small that goes all the way down. ..maybe re engineering those, or have options for different pocket configurations available- a second one thats got a few less could still be ok if the existing were a bit wider so they could be functional. He says he would prefer one larger pocket on the front waist area for a phone, perhaps one larger front plus one zip or button/ magnetic closed style on the front.
