Simple ModernBoot for 40 oz Tumbler with Handle | Anti-Slip Bottom Bumper Silicone Sleeve | Fits 40oz Travel Tumbler | Trek Collection | Midnight Black

This not only added to the appearance of my cup, it helps the grip and prevents it from sliding over easily. It helps keep it cool as well. It fit perfectly and matched perfectly. Super happy with my purchase.

Fits Simple Modern 30 oz tumbler snugly. Love it to protect my favorite tumbler from scratches in car cupholder. It also cushions my tumbler when I put it on a table so it is "quiet" instead of noisy. I bought the same color as my tumbler and I like the neutral seamless look. Would definitely recommend if you love your tumbler!

Great feel to this product. Easy to use! Fits well, dosent slip off! Protects the bottom of your cups from dents scratches or any types of damage that may occur without having one. Easy to clean and comes in many different colors! 10/10 must have if you havent got one already!

Fits great and matches perfectly. Love it.

This is perfect for my cup! Color is perfect. It fits snug so it was a struggle to get it on (I also have long nails so that was probably the culprit). This keeps it quieter and was exactly what I was looking for!

It works great on my Simple Modern 40oz tumbler. No complaints there. But the color is more green than it appears on amazon. It’s not a soft teal like pictured.

Simple Modern makes great water bottles and tumblers. I purchased the 50 oz tumbler sever weeks ago and have used it frequently. The tumbler came with a replaceable straw. I don't mind straws but prefer to "sip" the water. I decided to get the SM Tumbler Flip Lid. So far I am quite happy with it. It is easy to use and does not leak at least up to this point. It, like tumbler, is easy to clean/wash. The price was reasonable as well. A great purchase/addition to the SM tumblers.

Fits perfect an easy to put on! And it’s cute! I love the Simple Modern products and have quite a few. I wish I would have gotten this for my tan one because I banged it up already.

I bought this to go on my 30oz trek tumbler for when I need to use my cup for hot drinks, works perfectly, fits great and absolutely no leaking.

It's more straws for my Trek 40oz.

Tengo como 1 mes y medio con este aparato y hace mucho ruido de interferencia en la bocina al principio brillaba bien la luna por lo cual lo pedí, pero ahora ya no se ve nada la luna solo los led verdes me duró muy poco tiempo para el precio

I love these. Nice to have extras just in case

Got it to match up with my pink tumbler for warm drinksLove simple modern products
