My horse lives out over winter in a large field and it’s usually dark when I get there. Finding him in the dark can be a challenge so I thought this rug might help. I was sceptical thinking after he’s rolled will it still work? I can honestly say it does, it makes such a difference. The thread is woven into the fabric and feels slightly raised and really lights up in the dark. The rug also comes with field safe sursingles and will release if he gets stuck which is a great idea. This is a great quality rug and worth the money. Would highly recommend. In the attached photo he has rolled in the mud!
