BKBY Silicone Boot Compatible with Sinple Midern 24/30/40 oz Tumbler with Handle/Trek Pivot, Protective Anti-Scratch Bottle Bottom Sleeve Cover Compatible with Sinple Midern Tumbler

f you’re looking for a versatile and high-quality silicone tumbler boot, this one is a fantastic choice! i purchased one designed for the Simple Modern 24oz Trek Tumbler, and I was delighted to find that it’s also a perfect fit for both the 20oz Simple Modern travel mug and the 28oz slm tumbler. It does take a little bit of effort to inch it upwards on these cups, but the snug fit makes it well worth it. One thoughtful design feature that stood out is the tiny purposeful hole at the very bottom of the boot, which allows air to escape as you work it onto the tumbler. This makes the process much easier compared to other boots that lack this feature—definitely a smart addition! For comparison purposes, I also tried a boot designed for the 30oz Trek Tumbler on the 20oz travel mug and the 28oz slm tumbler. While it technically fit them both, it wasn’t quite as snug as the one designed for the 24oz Trek Tumbler. The 40oz Trek Tumbler boot, on the other hand, fits the 40oz tumbler perfectly—as you’d expect since it’s made for it. One thing to keep in mind is that the added thickness of the boot might make your tumbler a tight fit in car cup holders. My travel mug and 28oz SLM fit fine in my car, but my 40oz tumbler needs a little nudge to fit securely. That said, these boots are incredibly well-made. They’re thick, grippy, and do an excellent job of preventing your tumblers from sweating. They also stay in place when you set your cup down, which is a nice bonus. Overall, they’re a very worthwhile investment, and I highly recommend picking one up to protect your tumbler and make it even more functional! Side note: The 16oz travel mug and the 16oz, 20oz, 24oz, and 28oz slm tumblers have the same bottom dimensions.

Fits my Simple Modern 40 oz. tumbler, perfectly. The sage green is a perfect color match. You can't even tell it's on the cup. It is well made, durable, and prevents my cup from moving around in my car cup holder. It also prevents the loud clink every time you set it down. It was a great price and does exactly what I wanted it to do.

Perfect fit for the bottom of the Stanley 40oz Tumbler. I needed something a little higher so I can fit my Airtag holder in the bottom and this was more than enough. It was a little high so I lined it up with the original Stanley Boot (which is already perfect height to hold my Airtag holder but does not come in this color - Almond Birch) and I used the original Stanley boot as a template to draw a line on this boot and cut off the excess in a perfect line. Final product is exactly what I wanted since I was looking for a boot that is more cream in color but slightly darker and this Almond Birch was spot on - matches my Black Stanley 40oz Tumbler with a darker cream handle, black ProTour top, and Darker Cream Straw (which is actually from the ProTour top in Sage grey - looks cream but slightly darker than regular cream hence wanted this Almond Birch Boot).

I absolutely love my boot for my simply modern 40 ounce Tumblr. It’s not as sparkly as in the picture it’s more of a little bit of glitter on it. You can’t really notice it on the picture as much but I’m OK with it. It’s still fit snug it protects my cup from getting any kind of scratches. I wish it would’ve been a little bit more bling to it because as I touch it, the glitter stays in my hands so by me washing the cup out, I’m sure eventually I’m going to lose all the glitter on it and it’s just going to stay plain pink but that’s OK cause I just got this mug for my birthday so eventually I will be purchasing different ones but other than that, I’m OK with it. It looks nice.

Perfect boot for my tumbler. Ir fits perfectly. It makes it stay in place. I love it.

This sleeve fits my 30oz SM tumbler perfectly and I love how it softens the noise when setting it down on hard surfaces. I did remove one star because my tumbler no longer fits in standard car cup holders, and the crease from the packaging hasn’t relaxed even after a week. Still, it’s not a deal-breaker—overall a good purchase.

Works perfectly for our simple modern tumblers! The color has held up well and doesn’t seem to stain. Love how it protects my counters and table from my kids heavy hand!

The quality of this is really nice because it makes it to where my cup doesn’t slide. It also helped my cup fit into my car cupholder. I would highly recommend buying one of these!
