I have worn Carhartt double knees,while I climb, for years now. They held up the best so i just never tried different pants after finding them. They are great for resisting snags and tearing. But they are heavy and restricting in the crotch and thighs. I've had the same 5 pants for like 4 yrs now lol. What are some pants everyone else wears? I'd like to find lighter weight pants with better flexibility and are tough and hold up like Carhartts.
