Silicone Boot for Owala 40 oz Tumbler with Handle, Anti-Slip Protective Sleeve for Stainless Steel Triple Layer Insulated Travel Tumbler Accessories

I bought this for my Sipx 40 oz tumbler, and it fits great. I also used it on my other generic 40oz tumbler as well and it fit too. I bought it because I had dropped it and the bottom was a little bent so my tumbler rocked when set down on a flat surface. This did the trick and works well. I will say that when it originally came it was flatted and shrink wrapped so it was formed into a weird shape. But once on it fits great and you don't notice it at all. I also like that it makes the bottom non slip and helps it to stay put where it is. Overall I really like this product and would recommend it to others for their 40 oz tumblers.

I like this silicone boot just fine. The textured finish adds a little something visually. I was disappointed because it came in a vacuum sealed bag which left creases. Thankfully, the boot is texture so the marks aren’t that noticeable. The boot does its job and protects the bottom of the tumbler from scuffs.

This boot has been a great addition for my 40oz Simple Modern cup! It fits perfect and even fits in my cupholder! Protects the cup from scratches or dents from every day use

I like having a silicone boot on my owala cups. This boot came in a little smashed up but I was able to straighten it out to fit my cup. It went on easily and definitely protects the bottom of the cup.

The boot fits well and does a good job of protecting the base of the cup. The bottom edges of the boot that act as the base for the cup are too rounded, taking away from the stability and making the top heavy cup more likely to be knocked over. This boot would work very well for a cup that mostly gets put in a cup holder, but for one that's going to spend most of the time on a desk or counter, there are other boots that provide a more stable base.

Trick is to turn it inside out and put on because it’s a bit tight to get on and not designed for the “40oz” style cups. But it is great, well built and adds that little bit of protection that makes you feel good.

Exactly as expected! The color looks like the photos. It is thin, but not obnoxiously thin. It fits my Simple Modern 40oz Trek well.

I recently got this Silicone Boot for my 40 oz Tumbler with Handle, in the gray color. The anti-slip protective sleeve fits perfectly. It's made of durable silicone, and the grip it offers is fantastic—no more worrying about the bottom coating on my tumbler being scraped and damaged when I place it on a rough surface. Plus, it adds a nice touch of style. There are a few permanent fold creases in the silicone boot, but they are not too noticeable when fitted on the tumbler. Overall, I'm glad to have this accessory for my tumbler.
