The water resistance is OK when the coat is new. If your coat is worn a lot, before you bought it, the surface of the cloth is not plain. I do not know if I use the right words or expressions but what I mean is that if you iron the coat (outside) the surface will not "catch" the water. It just runs of. If this wont help, use a water resist reconditioning for cloth made in polyester and cotton. I believe that the cloth in the coat is 50/50 (poly/cotton). There is different methods to threat garments depending what brand of reconditioner. Some recommend soaking in water or using a washing machine. But add heat in any form: ironing or tumbledry.
This sounds very much like it is treated with a durable water repellent (DWR) coating. Generally, they are activated by heat (ironing/tumble drying). If the heat-treatment no longer works, you need to be careful about how you reproof the garment:
DON'T wash it with detergent (normal washing powder/liquid)! The detergent actually prevents the material from repelling water. Either handwash it in warm water, or use soapflakes (I think Fairy used to do some?). Better still, probably the best solution is to wash it in something like Nikwax Techwash. This cleans the material without ruining its water-repellent properties. Then treat with a product like Nikwax TX.Direct.
I've used Nikwax as an examle as it's worked for me (I'm not tied to the company, etc) but there are other treatments out there.
A top-tip is either handwash the garment (make sure the container is free of all detergents) or, wait until your mate buys a new washing machine and use that before he puts detergent in it! If you insist on washing in your own used machine, run it on two very hot wash cycles to try and clean most of the detergent from the machine.
OK, this all sounds like a lot of messing about but when you're lying there, cold and wet, becuase your jacket/clothing is sponging up water you'll wish you'd have made the effort.
Alternatively, for 20 quid, you could chuck the old one away and get another!
