All in all, I've been very pleased with this fly sheet. It's now held up the entire season, which is a true testament to its durability. Sure, it will never again be the brilliant white that it was when I first removed it from the package (Whisper saw to that within about ten minutes of my having put it on her), but it still does the job.
The fly sheet features belly surcingles which fasten tightly and securely. They're also easily adjustable, and the surcingles themselves are soft. The front closure has two buckles so that you can adjust it for the best fit, and the metal hardware has held up well.
I particularly like the fleece padding up by the withers, since Whisper has been rubbed there by other blankets before. The fly sheet is cut in a way that it does put some pressure on the withers, but the padding helps to lift and shift that pressure, and Whisper wasn't ever rubbed by it.
I had a bit of difficulty with the neck closure - something about the cut just didn't fit Whisper right and the neck kept sliding down and back. Once I'd adjusted it to the smallest setting, the sliding was reduced, but I still needed to go shift the sheet around at least a few times a day. It's not a sheet I'd recommend to use if you can't be there to take it off or reposition it at least once a day, unless the sheet fits your horse better than it did Whisper.
Lightweight and soft, this sheet helped to lessen the amount of flies that bothered Whisper. It's an affordable option and is one that I'd consider buying again. You can order the Upland Basic Turnout Fly Sheet from Dover Saddlery.
