Strategy for Annihilation of Cockleburrs

First of all, I’m seeking brand recommendations for lightweight, breathable pants that resist attachment of these dried, brown spurs sent from the Underworld. What is advised in destroying this noxious weed? I confess I’m a senior, a girl, disabled with osteoarthritis/ bad back, divorcing—so…poor. City Mouse spouse moved to Easy Street. I am stubborn, will work as hard and long as I am able. This rural east-central Kansas patch needs rescue and I need the right attire yesterday. Thanks, burr-busters.
