As riders and online shoppers, we know it can be tough to buy a new bridle or pair of boots without trying them on. That's why we moved the fitting room to your living room (or barn)! From breeches to blankets, if you or your horse can try it on, you can return it, free! Just use the pre-paid return label included in your order within 60 days from the purchase date. And of course, please make sure the item is in like-new condition with original packaging (we said 'fitting room', not 'war room'!).

Why We Love This

Fly protection has never been more beautiful! The fabric of the Kensington Polymax Fly Sheet shimmers in the sunlight and provides durable protection against biting insects. Ultra breathable, the sheet keeps your horse comfortable in the summer heat. The Kensington Polymax Fly Sheet features a European cut

    Kensington Polymax Fly Sheet is rated 4.4118 out of 5 by 17.
    Rated 5 out of 5 by from Durable but soft! 78" fit true to size (maybe hair on the small side). Soft fabric doesn't rub but is thicker than most fly sheets so it has stood up to lots of horsing around.

    Rated 4 out of 5 by from Kensington polymas flysheet Haven't used but the fit is good, shoulders are or seem a little tight-wish it had gussets at shoulders. Overall a good fit. Nice color-fun.

    Rated 5 out of 5 by from Great looking and effective! This fly sheet has already helped my young gelding immensely! Terrific protection from flies, mosquitos, gnats and other biting/irritating insects. Helps keep his coat smooth and glossy, too. Fabric is soft, sleek and comfortable. Straps are easy to adjust. Fit is true to size. Nice color (we got the blue). Terrific investment!

    Rated 5 out of 5 by from Good for the Fly Sheet Shredder! My OTTB mare has been wearing this 24/7 for the last month. She is HARD on fly sheets-but so far, this is holding up. She is outside 24/7 with another horse, & the sheet does have 6 quarter-sized holes in it from her rubbing on the fence, but they aren't tearing & she is not shredding this sheet. I ordered her a 75 as some reviewers had said they felt the sheet ran large, but I think her normal 78 would perhaps fit a touch better. It does seem to be snug over her chest (I wish it had a velcro closure there as well) and maybe a hair short along her back, but it works. I LOVE the snap & D-ring belly closures. Every blanket should have those! Overall, I am very happy with it, the colors are fun, & mine came with an awesome warranty card from Kensington.

    Rated 5 out of 5 by from Great fit! This fly sheet fits great and is easy to clean. My horse hasn't been too hot in it and hasn't had any rubs.

    Rated 4 out of 5 by from Very pretty! I bought this about a month ago. My horse wears it every day for turnout. It looks lovely, the blue is a beautiful color on him. When he rolls himself in the mud, I can just take the sheet and hose it off, hang it on the fence to dry, and it's clean, ready for the next mud bath. The only thing I am disappointed about is that it is a bit small across the chest, and the two sides don't meet, the buckles are fine. It fits well everywhere else. I would buy it again, and would recommend it.

    Rated 5 out of 5 by from Effective protection, durable fabric, good looks! I bought this sheet about a month ago for my TB. It keeps the flies off well -- even the horseflies, the bane of my horse's existence, seem to be unable to bite through it -- and looks great in addition to wicking sweat nicely. (I bought mine in Ice Blue, which looks good on my gray horse). So far it's holding up quite well under 15-hour-a-day turnout use (although my horse is currently on his own and so I can't speak to how durable it might be when another horse is chewing on it). The only downside is the odd fit: I bought my horse's usual 78 but found that although a 75 would've worked better lengthwise, the sheet is narrow across my horse's wide chest, so the buckle's on the last hole, resulting in a pretty big gap. I'm still quite pleased with the sheet overall, though, especially for the reasonable price. Good product!
