Has anyone tried Fryskware blankets? https://www.fryskware.com/en/our-horseblankets/winter-rain-ware/
I saw them mentioned in another post about horses who may require a lower/deeper cut neck opening, but no one seemed to have experience with them specifically. I have a perch x tb and the big fella blankets just slide back and end up too tight around the neck/withers.
*I read through the other post extensively and may try Weatherbeeta next as it appeared to be the winner, but curious about Fryskware as they sound lovely (although not cheap!).
