Let’s talk khakis

Looking for a good couple of pairs of khakis I can get into some big maneuvers such as a 90/90 stretch, deep squat/lunge, hip flexor stretch without worrying that I’m gonna be SpongeBob on the beach looking like a fool that ripped his pants. Also want something that doesn’t look like I’m gonna sell you a wrist watch at JCPenneys, more casual less businessy.

TIA
