Adding leg straps to Horseware blankets

Thanks! I didn’t know these existed. I suppose I’ve never seen one in use. Thanks

The Shires ones are on Amazon, in several sizes and from multiple sources (click “other sellers” on the right).

Shires PVC tail strap

I have found in my 30 plus years of blanketing horses that leg straps keep the blanket more closer to the hindquarters…so the bottom of the blanket flaps a lot less in the wind and is therefore warmer.
As far as I can see, tail straps are useless.
I also don’t see the purpose of “leg arches”… which do nothing to provide more freedom of movement. But they do leave the horse exposed to the cold air.
