I have this cooler and love it. Lightweight and easy to throw into the washer at home. It's sturdy enough that I can throw my horse in supervised turnout with it on (only in the arena where there's nothing for it to catch on). Cheap too
I have 4 of the Amigo Mio turnout sheets. I paid like $35 each on clearance. My horse keeps his blankets in pristine condition but I gave one to the blanket wrecking pony at the barn and he hasn't even managed to snag it and he's had it for a year now. Completely destroyed 2 midweight turnouts in that time though!
If you are looking for blankets, go to sstack.com they have a HUGE selection and they are VERY cheap. They have a lot of sizes there too! They are also very durable. I use them for all of my horses and I love them so much.
