I would like to make my clothes to repel water (with hydrophobic coating?). Any suggestion of not-so-expensive method to achieve this?

3M makes a spray for this purpose "Scotchgard". It's been around for decades. You'll need to re-apply it every year or so for the water resistance to persist, and especially after laundering. Beware, once your clothes repel water, they will also repel sweat, which may leave your skin wet beneath.
