I bought one of these as a trial, and am very glad I did. I am not lucky enough to have a separate washing machine for washing horse and dog stuff (with 4 horses and 6 dogs, that adds up to a lot of saddlepads, girths, boots, rugs, towels, dog beds, etc) and although I always do a full empty wash with cold water after a batch of dog or horse stuff, and wipe around the drum and seals, I must admit that hairs do still appear on any clothes that go in the next wash or three… never popular!
I’d say to buy the biggest bag you can, it just gives more room for good washing. I have the Large size. Don’t over-stuff it, I tend to fill it about 2/3 full at most. I always rinse muddy things off well first under the yard tap, then bung them all in the orange bag (impossible to lose in the tackroom, yay!) The zip is good quality and strong, no problems at all. Just stuff the orange bag in the machine, add washing liquid, and I always add an extra rinse cycle, after a horse of mine on loan lost the hair over his entire saddlepad area, after the rider didn’t rinse it properly and the horse reacted to the remnants of detergent – it looked like rainscald, just awful.
When the wash is done, just remove the clean items, take the bag into the garden and turn it inside out to shake out the hairs, grit etc, and it’s ready to use again.
It stops that irritating noise of girth and rug buckles crashing around the drum during the wash too!
Highly recommended, I don’t know how I managed without it. I intend to take it to events and put things in it after washing off them after xc, so it can go straight in the machine on getting home, that’ll streamline everything nicely!
