I have used Tactical 5.11 cotton pants since they were originally designed by Royal Robbins for over 20 years. The original had problems with the crotch splitting which Tactical 5.11 has solved. However, the leg pocket has always interfered with my knee if I carry anything big in it. The price was also just increased on the entire line so I purchased the less durable polyester version. It's lighter but I just found L.A. Police Gear Urban Ops pants are a much better deal on Amazon at $ 28.99. The Urban Ops pockets don't interfere with you knees, the one drawback with this design is that the pockets aren't as deep.
