Stanley Quencher Boot and Straw Cover Cap | Anti-Slip Silicone Protector for Tumbler with Handle | Accessory Set for Stainless Steel Drinking Cup | BPA-Free

Durable, fits and grips the cup well does not slide off. Love the color, over all would buy again. The price fits the product.

It fits perfectly the 40oz cup, perfect grip, color, protects perfectly, it looks good, and protects from leaks! 😍😍

These fit the Stanley bottles perfectly. They are a much better fit than the knock offs because they fit the bottles exactly. Got these for my Stanley tumblers and was glad I purchased them. They are great quality and much thicker than the knock offs that I have. Very pleased with my purchase. They may cost a little more, but definitely worth it and they have the Stanley Lifetime Warranty should anything happen to them.

I really like the function ability of this product. It doesn’t split or move as much much as it would without it. I also love the straw cover cap. It helps keep the dust and germs out. The color was exactly how it looks in the picture and went great with the blue Stanley I had previously purchased. It also slides right on there without any issues and does not fall off.

It fit perfectly, and I didn't realize until I put the cap on that it looked like a mini upside-down Stanley. It was so cute! Very easy to put on as well. It also makes the Stanley less likely to fall over, and more silent when setting down.

About a week ago, I purchased a 40-oz Stanley Quencher. Normally, I am an Owala girly because of the size and convenience; however, it is a pain in the butt to clean daily and that lid always gets moldy or dead skin cells in it even after a day or within an hour of washing it, and I am a very clean person. I had always seen people with Stanleys and found them to be a bit too big for me, but I caved in for the sustainability of it and long-term quality. I'm proud to say I LOVE this Stanley, and I have officially converted to being a Stanley fan! At first, I was skeptical about purchasing a boot and straw covers, but I know I don't want a dented Stanley bottom or unwanted outside dust/germs/etc getting into my straw. I decided to purchase it anyway, and I am so happy I did! The boot is so easy to get off and on for cleaning, and so is the straw cover. It's durable and has a great, clean asthetically pleasing look that is grown up and minimal. The stability of the product is also trustworthy since it is straight from Stanley itself and not some third-party brand that may be more likely to be of lower quality. The strawcovers themselves are not bulky and distracting, and are also easy to clean! It's nice that packaging came with 2 incase you break one by accident or lose one! It's safe to say I am very pleased with this purchase!

I wanted this for the straw covers and they fit well & work well. There were cheaper versions but I wanted the Stanley version - I figured that guaranteed they'd fit & work. Pricey but beverages are now protected.

Great boot for the Stanley cups fits perfectly and the color matches.
