12 PCS 70mm Bottom Protective Silicone Sleeve Cup Mat Heat-Resistant Water Bottle Holder Mat Non-Slip Cup Mug Coaster for Insulation Tumbler Protector Bar Coasters - Multicolor

These worked perfect for my Owala Sway bottles. Easy to put on and clean.

I didn't really need 12 of these but it was cheaper to buy this set than buying a few individually. I needed something for my slim insulated stainless steel bottles which measures 2.75 inches in diameter at the base and about 0.75 inches in height. For one bottle I didn't want a high boot because it would cover my name which was custom engraved. I came across these and I'm glad they fit perfectly. They do stretch just enough to get it on. I was able to use these on 4 of my bottles. They do fit better on a bottle with a base that is not curved. They also fit fine on my bottles that are slightly curved, it just takes a little more adjusting. This silicone don't seem to attract as much dust or lint as another type of silicone bottle boot that I have. Some of the colors received aren't exactly as pictured (like 1 or 2 of them). They all came individually wrapped so it's nice for gifting. They are on the thinner side. It will definitely protect from scratches and now there's no more noise when putting my bottle down. I'm not sure how protective it would be during a fall. Remember to measure and order the correct size.

I purchased this silicone boot to protect my water bottle from dents, but it failed completely. After a simple waist-height drop, the bottom of my bottle dented badly, despite the boot being on. The material is thin and offers little to no real impact resistance. While it fits snugly at first, it can easily slip off if rubbed or nudged the wrong way, especially when pulling the bottle out of a bag or car cup holder. It might add a pop of color, but it’s unreliable when it counts.TL;DR: Slides off easily and doesn’t protect from dents—more decorative than functional.

We got a couple of stainless steel mugs that have metal bottoms. They were noisy putting down on a table and concerned to slip. These slipped on easily and snuggly! Perfect fit.Just didn't need so many though! Good price but too many. Wish they would have offered half for half the price.

These are a great fit on our 30oz Owala Sways. They cover enough to keep the bottom clean and stay on securely. We appreciated having a bunch of color options.

Product is as advertised, just measure and read carefully. This "70mm" bumper fits many sizes, but not all. From personal experience, it stretched to and worked on a 99mm Yeti - but not even close on a 114mm 40oz hydroflask.

All were packaged with individual wrappers and fit great! They fit like a glove for the ones with the exact measurements. I even tried the pink one which is bigger in diameter. Although it doesn’t have a perfect fit, it still works despite being a bit crooked. This goes well with colors as I didn’t think the orange would go with my blender bottle’s color. These are fantastic for your money! Puts my mind at ease as I carry these to school and work everywhere. I just received them so I can’t speak for longevity, but I really enjoy them and they look like they will do the job of preventing scratches and scuffs on my bottles. :)

Love these. They are well made, durable, fairly thick but not too thick. Not overly sticky. Fits on my Owala Smooth sip
