Simple Modern 40 oz Trek Tumbler with Handle and Straw Lid | Cup Holder Friendly Insulated Stainless Steel Travel Mug | Almond Birch

The one that never drips. After experimenting with numerous tumblers and facing constant disappointment, I have finally found the perfect one that checks every box. What sets this tumbler apart is its intentional, minimalist design. Unlike my bulky 40oz Stanley, which frustratingly refuses to fit in my car’s cup holder, this sleek model slides in effortlessly. The engineering is also superior; the weight distribution remains balanced even when full. It avoids the top-heavy, cumbersome feel of other brands that are either too wide at the brim or excessively tall, making it a breeze to carry throughout the day. The aesthetic is equally impressive, featuring a sophisticated, dark matte purple finish. Its thermal performance, however, is the real standout. During my most recent test, I poured in two refrigerated water bottles with no ice; the water remained crisp and cold for a full 48 hours, only beginning to lose its chill on the third day. I have no doubt that adding ice would extend its temperature retention even further. This is an easy 10/10 recommendation.

Will definitely buy again! This is my second Simply Modern cup and will continue buying the brand. Bought many months ago and still holding strong. Clean look, fits in regular cup holders, useful handle, straw hole is leakproof (besides straw itself). Straw is bendy and durable. Lid is leakproof and tight seal. A cheaper (better) cup than the other big brand. (You know the one)

Simple cup has quickly become one of my favorite drinkware brands. The quality is impressive—lightweight but sturdy, with a sleek design that’s easy to hold and fits perfectly in cup holders. One of the standout features is the insulation. My drinks stay cold for hours, even in the heat, and hot beverages stay warm without the cup getting too hot to touch. The lids seal tightly and don’t leak, which is a huge plus for anyone on the go. I also appreciate the variety of colors and finishes; everything feels modern and thoughtfully designed. Overall, Simple cup delivers on both style and performance. It’s a reliable everyday cup that feels premium without the premium price tag. Highly recommend!

Simple Modern is my favorite brand for tumblers. Have a Stanley and a Yeti but the Simple Modern tumblers perform just as well, if not better for less money. I can fill it with ice at 7:30 in the morning and continuously fill it with water all day. Ice lasts until about 4:30 before melting. It keeps my drinks cold in a hot car for hours. The handle is large and fits my hand well. Love that I only have to turn the lid 90 degrees to secure it. Cool thing is, if it tips over, the water will only leak out the straw if it’s fairly full. Sometimes, the water doesn’t leak at all. Bonus of the Simple Modern brand is that you get two straws so you have a backup!

Absolutely love this Trek Tumbler! It holds ice for hours sometimes all day which is perfect for long drives or busy workdays. The handle makes it super easy to carry around, and it actually fits perfectly in cup holders, which is a big plus. I originally got it as a gift, and the person I gave it to uses it every single day. Great quality, great design definitely worth it!

Great tumbler, exactly what I was looking for. The search was exhaustive! Pros: - Great handle that fits all my fingers, a lot of ones under 40oz only fit 3 - Uncomplicated lid, just a straw hole, which is only thing I ever use. Good wide straw too. Also handy that you can lock it in 4 different positions. - Fits my car's small cupholder which doesn't have much overhead room (Toyota Prius C). Most good tumblers are 40 oz, which don't fit - Sleek matte look. The other colors I've seen in person look good too. - Actually leak proof, unless you turn it upside down of course - Seems sturdy and is easy to clean, no areas that are hard to get to because top and bottom of lid are flat. Think this will be with me for a while! - Has inspired me to write what might be my first Amazon review Cons: - May not be as insulated as some, at least how they're advertised, I haven't used the big brands like Stanley. If it's full of ice it won't melt for at least a day though

I’ve been using the Simple Modern 40 oz Trek Tumbler for a few weeks now, and overall I’m really impressed. It keeps my drinks cold for hours—even after sitting in a hot car, I still come back to ice. The handle is comfortable and makes it easy to carry around, and the tapered bottom actually fits in my car’s cup holder, which is something a lot of big tumblers can’t do. The design feels sturdy and high-quality, and I like that it comes with multiple straws. The whole thing is easy to clean, and the finish still looks brand new. My only minor complaint is that it’s not completely leak-proof. If it tips over with the straw in, you’ll get a little splash. It’s also a bit on the heavier side, but that’s expected with a 40 oz insulated cup. Overall, a great everyday tumbler—durable, stylish, and excellent at keeping drinks cold.

Perfeito! Gela bem e chegou muito rápido.

ممتاز شكله كيوت مررررة و يحفظ البرودة وقت طويل

It arrived in a box that had clearly been opened and sent before. The bubble wrap wasn’t even on the bottle but just sat at the bottom. There were finger prints on the inside of the bottle as well. Kind of dissapponting. :/

There are no spills on this when tilted side ways. Color is nice and keep my water chilled for a long time.

All i can say is WOW WOW WOW! my water stays cold for days, there is still ice 24 hours later! and i love the simple design, leak proof, and color, easy to clean and easy to hold, does not slip on table. I made some research on which tumbler to get for cold water duration and i decided on simple modern.
