CARWORNICMen's Hiking Tactical Trousers Lightweight Rip-Stop Combat Work Cargo Pants with Multi Pockets

Dose tactical trousers water-repellent?good for work?

I need a good stretch/flexy pair of trousers. Are these trousers stretchy?

Is this tactical pant durable?

The front pockets look they all overlap vertically (hand pocket, drop pocket, and zip pocket). If you fill them all up, does it get cramped and bulky?
