Best Sporting Optics Covers of 2026

"I was pleasantly surprised by how well this cap fits—the soft rubber boot wraps perfectly around the eyepiece. It’s not stiff plastic like others I’ve owned and the cap flips up quietly and smoothly."

"After losing my original cover during a hunt, this replacement came through big time. It fits my Nikon M308 snugly, so I'm confident it won't fall off. The quality looks good, and I'm looking forward to using it for several seasons."

"It took some effort to get these on—using a little soap helped them slide into place and now they stay put. The fit is firm and the pricing is fair for the quality. I followed the sizing instructions and they were very clear compared to other brands."

"I was skeptical about the price, but after taking it out in rain and dust, I was impressed with how snug and watertight it fit on my scope. Installation was a breeze, and it didn’t add any noticeable weight. For the cost, this kind of reliable protection is hard to beat."

"I've relied on these covers for decades—my first one is still going strong after thirty years! They seal out moisture and debris, work perfectly on different scopes, and are surprisingly durable and convenient. For something so simple, they really do the job."

"I bought these for two scopes, one with a large objective, and was pleased with the stretchy fit and how good they look. I appreciate the functionality and convenience compared to the usual plastic caps, and so far, they’re holding up well."

"I picked the 49-54 mm cap for my Vortex Crossfire II 4-12x44 and while it’s not an exact fit, it stays put and handles rough use well. The material feels sturdy, installation was quick, and it opens with minimal sound—great for hunting. My only nitpick is I wish it fit a bit more flush, but overall I’m very happy and would buy again."

"I own several scopes and red-dots, and these covers have fit perfectly on every one. No matter the brand, Monstrum’s covers deliver solid quality and a fair price. I keep coming back for more and recommend them to others."

"These scope covers are a great value as long as you measure your scope before buying. They fit mine perfectly and I’m really pleased with the purchase."

"I received my cover today and it fits my older Millet scope with a 50mm end perfectly. The quality is impressive for the price, and it offers solid protection for my scopes. I've already ordered more for my other optics because I'm really satisfied with how well these work."

"I've tried every size available for my different scopes, and these covers fit great and stay in place. They even protect the turrets and allow airflow, so I don't have to worry about moisture. The construction feels reliable and I'm very pleased overall."

"The cover fits as expected and I appreciate the reinforced end that protects the optic. Like someone else pointed out, the white lettering isn't my favorite, but I just covered it with a marker. For the money, it's a worthwhile purchase and I'd get it again."

"I put this on my .350 Legend Leupold scope and found it to be a perfect fit, providing solid protection without adding any bulk. The quality is impressive and it's simple to use. Definitely worth purchasing for anyone wanting good coverage."

"For my setup, this cover fits very snugly—almost too snug—which might actually be helpful in rugged conditions. However, it can be difficult to remove quickly. If you’re planning on using it in the field a lot, I’d suggest going a size up. Still, it’s a nice, reliable product if you don’t need to take it off in a hurry."

"I recently bought this for my Leupold VX-6HD 4-24x52mm Riflescope, but unfortunately, it was much too small for my scope. There is very little stretch, so it might only fit scopes up to 44mm. Sadly, I’ll have to return it, even though I was hoping to stick with the Leupold brand."

"I’ve used Butler Creek scope covers for years, and the Model 11 Eye fits perfectly on my Leupold 2x7 33mm Freedom series. The durability and reliability keep me coming back to this brand."

"The spring-loaded flip-up lid is a standout feature—it’s fast, secure, and stays in place during recoil. The quality and attention to detail are excellent. I do wish Bushnell included these with every scope purchase, but overall, I’m impressed by the craftsmanship and long-lasting design."

"My scope cover fits snugly on my Nikon Prostaff P3 4-12x40 eyepiece and offers good protection for the price. It’s not the quietest when opening, but for a budget-friendly option, I’m pretty satisfied."

"I took this cover on a week-long backcountry hunting trip in Colorado with my Leopold 3-9x40, and it performed flawlessly. It kept out moisture, dirt, and brush, creating a tight seal for my glass."

"I put this on my Burris 4-12-42 and found it was a stretch to fit, but it works. If you have a scope any larger, it might be a hassle to get on and off. I might consider neoprene next time if this gets too tricky."

"The description was accurate, and it fits my standard size scope perfectly. I’m confident it seals out dust much better than the typical plastic covers and should be rainproof as well."

"I've tried several scope covers, but these stand out for their superior quality and perfect fit. They slide on easily and keep my optics protected. No more worrying about losing flimsy covers—these are very functional and dependable."

"After years of sticking with other brands, I finally gave these a shot. They're a clear upgrade, practically indestructible, and the three-position cap feature is a huge plus. For the price and lifetime warranty, it’s honestly a bargain."

"I chose the size 50 objective caps for my Viper HSLR, and they fit very securely, though they do take a bit more effort to install compared to others. The extended silicone section offers better grip, and while the opening tab can slightly interfere with the bolt, it’s not a big deal for me. Overall, these are a big step up from basic covers."

"I was really impressed with how snugly and securely this cover fits my HoloSun 507K. It feels like a second skin and gives me confidence that my sight is protected from dust and scratches. I especially appreciate how it acts as a shield during cleaning—the cover keeps cleaning solutions and debris away from my optic. For the price, it's a smart investment for anyone who wants reliable protection without breaking the bank."

"These covers fit my Holosun optics very snugly. While that means they're a bit tricky to take off in a hurry, they do an excellent job of protecting my sights when stored or not in use. I don't use them while transporting my firearm, but they're great for storage and peace of mind."

"The soft rubber material and tight fit make this cover feel durable and effective. It fits my Holosun 407k perfectly and goes on smoothly. For the value and protection it offers, I'm really satisfied with this purchase."

"I've tried several scope caps, but these are by far the best covers I've purchased. The rubber material feels durable and fits my scope tightly. It did take a bit of patience to get it on, but once in place, it stays put and offers great protection."

"I use the Defender flip cap on my Eotech Vudu 1-6x24, and it’s a perfect fit. The cap is much more affordable than other options, but the quality and function are just as good. There’s plenty of clearance for zoom rotation, and the cap lays flat. I’d highly recommend it to anyone looking for reliable scope protection."

"The Vortex Defender caps are a major upgrade over standard covers. The build quality is impressive, offering both robustness and flexibility. I really appreciate that they stay secure even under recoil and are compatible with different scope brands. I find them to be well worth the investment for anyone serious about protecting their optics."
