I bought this fly sheet about three, maybe four years ago and have been able to reuse it every season. It fit my OTTB perfectly. I was a bit worried when I got it because the material is very thin....but no tears or anything after all this time so I’d say it’s good! I unfortunately lost my horse to colic last year and have a new horse (also an OTTB)...he’s a bit wider in his shoulders than my last, and this sheet is too tight for him, and a bit short so his tummy hangs out.....so I’ll be finding a different sheet for my new horse. But otherwise, I was very happy with the quality of this product!
