AIERSA 2Pcs Silicone Boot Suitable for Simple Trek 40 oz Tumbler with Handle, Protective Water Bottle Bottom Sleeve Cover, Tumbler Accessories, Clear

Overall I have no real complaints, it does exactly what you expect it to. This silicone boot is a fantastic investment for anyone who wants to protect their Simple Modern tumbler while adding a pop of color and functionality. Pros: - Perfect Fit: The silicone boot snugly hugs my Simple Modern Trek 40 oz Tumbler, offering excellent protection. - Enhanced Grip: The textured surface provides a secure hold, even when my hands are wet or sweaty. - Prevents Scratches: Keeps my tumbler scratch-free, preserving its sleek appearance for longer. - Heat Insulation: Acts as a barrier, preventing condensation and maintaining beverage temperature. - Stylish Addition: Available in various colors, adding a touch of personality to my tumbler. Cons: - Limited Color Options: While the available colors are nice, a broader selection would be appreciated. - Slightly Pricey: Could be seen as a tad expensive for a silicone accessory, but the quality justifies the cost.

These fit perfect! easy to clean! Have lasted a year already! No stretching or any issues! Great for protecting those water bottles from drops!

I wasn't sure if I was going to like this or not, but I originally bought it for a brand new Simple Modern tumbler, 40 oz, from Amazon. The tumbler soooooo didn't work out (too long a story), and then of course, this silicone bottom cover came in after I returned the tumbler. So, I tried it on my Yeti, not expecting it to fit, and it worked beautifully! I spent so much $$$ on this damn tumbler, and I was always having to be super careful that I don't bang up the bottom. With this cover, it gives me peace of mind that it's snug, easy to put on and off, and will give it better protection...and it washes great! A definite buy for sure!!! I just ordered the glow in the dark one, and I'm dying to get that one in a day or so....what fun!!! ; )

Fits great on the bottom of my Simple Modern water bottles!

Fits and protects tumbler

Definitely fits and protects my 40 oz Simple Modern Trek, but now it doesn’t fit in my SUV’s cup holder. I ordered the clear-ish one, but it’s really opaque white.

My filled mug has a steel bottom and can slide easily on a hard surface. Additionally, it would rattle in my truck's cup holder and it was a possibility that it could fall over. They don't slide and I'm confident that it won't chip the paint on painted surfaces now. It isn't so tight that it is hard to remove the cup from the holder either.

Perfect for my SM cup. It’s snug & has protected from bumps and drops, but not too difficult to remove for cleaning. My only slight issue is that it is a super tight fit for my cup holder, making it almost not fit, but it’s not a big enough deal to dock a star; I’d rather the protection for my cup.

Es una excelente opción para no dañar tus vasos creo que es mejor prevenir accidente.

Love them !! Hence I bought 4 of them

Justo lo que necesitaba para la base del termo.

10/10 quedó perfecto!

El material está bien , el precio acorde pero en la descripción dice que es para un termo de 40 Oz y no le queda es mucho más pequeño… creo que si deberían hacer la corrección porque Justo lo pedir para ese tamaño y en el video se ve la diferencia
