The best tactical pants that I have bought are the 5.11 Stryke Pants with Flex-Tac. I have bought several other tactical pants from other makers and none of them are as well made as the 5.11 Stryke pants nor do the others fit as well.
I bought them for work because they look professional and are made to last with plenty of pockets to store stuff. The material is rip-stop which is a material that does not tear if cut or punctured. It’s super tough and durable. The pockets are very functional and heavily stitched. The legs fit perfectly and are very comfortable. You can feel the difference between these and others like the Condor tactical pants. The 5.11 Stryke pants are way heavier. They are machine washable too. If you want a serious pair of tactical pants then buy these. They are not cheap…$75 at 5.11tactical.com. Here is a link where you can get a great price ($56) on them…5.11 Stryke Tactical Pants with Flex-Tac at Amazon.com
