Kensington SureFit® Protective Fly Sheet w/ Leg Arches Made Exclusively for SmartPak is rated 4.3 out of 5 by 51.
Rated 5 out of 5 by from Fits so well! So happy with the durability and fit of this fly sheet!

Rated 1 out of 5 by from 3 Weeks, Already Ripped I purchased this fly sheet less than a month ago and it's already got non-seam rips along the back left hip. No repair kit was included, nor do I know how I would go about repairing it on my own, due to the unique material. Extremely disappointed, especially at this price point. I expected a lot better.

Rated 5 out of 5 by from Its my invisible groomer. when I return from 4-5 hour trail ride especially in winter (although this is desert, it gets cold too) my horse does not like a shower. I scrape what sweat I can and put on the Kensington. If necessary, a medium/to heavier blanket at day I usually have a pretty clean and happy horse. My two horses get a new Kensington every 1-2 years. One small problem. I have to insert /sew in soft material on the insides where the buckles create a very heavy, ruff area at the shoulder and rub off the hair. Kensington reps nicely tried to explain that gaited horses simply have a different build and create their own problem... I still love the Protective sheets and deal with it.

Rated 2 out of 5 by from Started fraying after a few wears I previously purchased an Original Kensington fly Sheet and it lasted me (on same horse) for almost five years. When I saw that Smartpak had its own Kensington fly sheet at a slightly cheaper price, I figured it was a win win. Unfortunately, after a weeks of wear, the Sheet began fraying at several points along the back. This sheet won’t last me another season for sure. Very disappointed in the lack of durability that is typically expected of a Kensington. Next year I will go back to buying the original version, not Smartpak’s version.

Rated 5 out of 5 by from Great Fly Sheet I bought this blanket after purchasing another brand and it ripping within the first week. My horse is not the easiest on his blankets and I have been very happy with this one. It is not showing any signs of wear and my horse has been wearing it every day since it came in the mail about 3 weeks ago.

Rated 3 out of 5 by from Didn’t work long-term Bought a year and a few months ago and it’s pretty tattered (was hoping it would last through a couple summers.) It’s beautiful and does it’s job while it is intact. After one summer, all but 2 of the clasps are broken. The clasps rip holes in the sheet. The mask’s padding has separated from the mesh part, so bugs can get in. Smartpak couldn’t help me with a replacement because it was a couple months after a year from buying it. For the price point, I’ll probably go with a different sheet set for future summers.

Rated 3 out of 5 by from A little disappointed The fit compared to the OG Kensington is small. Quality is great and like crisscrossing belly straps can the old single straight strap style. BUT the binding for the leg straps on the outside of the sheet is catching tail hair and breaking/pulling it out. May end up returning it as it’s a bit snug and eating my mare’s tail too.

Rated 5 out of 5 by from Friesian proof! Let me start out by saying I have a Very, Very busy 4 year old Friesian gelding that has literally ruined other fly sheets in a matter of days. I love this Kensington fly sheet for so many reasons. Side note he wears it 24/7 and lives outside. 1. He has not been able to destroy it ! Nor has his pasture friend!(there are a few small holes of attempts but he continues to be unsuccessful. 2. He is black so it has definitely helped with fading out since he lives outside and it keeps him cooler ( we live in Colorado) 3. He stays clean! And seems very comfortable in it. No issues with rubs. Amazing product, definitely worth the money !!
Date published: 2020-08-05
Rated 4 out of 5 by from Very durable, but caused rubs on my mare I bought a 75" from another website for one of my mares and since it fit so well, I decided to buy a 72" from Smartpak for my other mare who is much shorter backed. The sheet appeared to fit her perfectly, but after just 3 days, my mare's shoulders had rub marks and no hair. The 75" from my first mare appears to fit her well at the shortest adjustment. Thanks to Smartpak's wonderful customer service, I will be able to exchange the 72" for a 75". For those of you whose horses got rubs from the sheet may want to try a size up.

Rated 3 out of 5 by from Nice sheet, can't use This is a very durable sheet, great buckles and fabric, but leaves rub marks on my horse after just one night of wear.
