I'm not associated with this company in any way. I've used their gear for a number of years and found it to be extremely durable. The company specializes in military field gear (very heavy duty but you pay for it in wieght) but their field clothing line is the standout. All of their clothing is stitched with fishing line or something close. Large buttons on the pockets so you can access them with gloves. Their solid color pants and shorts are my go to for just about everything outside. I run a range and am constantly on the ground, in the mud or crawling over something and I've never ripped out a pair. I like traveling in them as I can carry a reasonable amount of gear without feeling overloaded. Their GP coat with removable liner makes a great camping coat and has plenty of pockets for snacks, gear, pets, small children....... the price is pretty amazing for what you get.
