This Hardland tactical pants are made out of a polyester (65%) and cotton (35%) fabric combination which makes them very durable. The seat and knees are double-reinforced, so I'll be able to bend, seat, kneel, or crawl comfortably if needed. These pants have multiple pockets specially sized for tactical use. The only cons I can think is the pants might not suit for wearing in summer, since its heavy-duty fabric--polyester will not allow to breathe as well as cotton would.
