I buy good rugs. I spend money and, in retrospect, I have learned that, in the meanest of weathers, you get what you pay for. There are certain brand names I stick to and trust. I get rugs repaired properly. Rainsheets must be waterproof and all rugs must have leg straps - I get them put on if necessary as I am fed up of looking for rugs in a 50 acre field After a Force 12 Storm. If you buy cheap EBay crappery, you get exactly that. A false economy Imho And waterproof must mean just that. WATERPROOF!
oh yes, and I also like front leg darts so the horse can actually walk and not feel restricted.
