I used to carry my water in an old Tervis tumbler, but it leaked and got condensation and didn't stay cold for long, so I decided to replace it. Rather than jump on the Stanley or Yeti bandwagons, I did some research and found this brand topping some reviews. And I really like it. It comes in a variety of colors. The included straw fits through the opening very snugly so it hardly leaks at all if you tip it over, it has a screw-on lid so it doesn't just pop off, and it does keep my water cold, with the ice lasting all day. The base is a little small for the cupholders in my 2008 Escape, so it jiggles a little, but it still rests fine. That's my only complaint, and it's not significant.

The Simple Modern 40 oz Trek Tumbler in midnight black is both sleek and practical. The color looks really nice in person, and the design feels modern without being bulky. The handle and straw lid make it easy to carry around and sip from throughout the day.

What I love most is how well it keeps everything cold – drinks stay chilled for hours, which makes it great for daily use, long drives, or workouts. The large capacity also means I don’t have to refill it constantly. Overall, it’s a great tumbler that does exactly what I want and looks good doing it.

The color is exactly as pictured. Keeps my water cold all day and the perfect size for all day use. Very durable and sleek looking. I wish the handle was the same material as the rest of the bottle but it’s not a big deal. Especially considering the price is more reasonable than most nicer water bottles! Highly recommend!

really fantastic cup for the price. keeps ice all night long, really simple design and completely leakproof lid unlike my stanley. I like simple design, easy to use and easy to clean, for my everyday products and this fits the bill. I also got a silicone sleeve that helps with noise.

Love this tumbler. The 40 oz size is perfect for all-day use and keeps drinks cold for hours. The handle makes it super easy to carry, and it fits in my car cup holder which is a huge plus. The lid is secure and doesn’t leak, and the straw is sturdy. Great quality for the price—I’ve already bought more for my family.

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.

I actually bought the Simple Modern 40 oz Trek Tumbler with Handle and Straw Lid as part of my teenage daughter’s Easter basket, and it ended up being one of those gifts that’s both practical and surprisingly exciting.

She’s constantly on the go — school, work, friends, repeat — and was always grabbing plastic water bottles on the way out the door. I wanted something she could just fill and take with her. This has been perfect.

It holds plenty so she’s not refilling all day, but somehow still fits in her car cupholder. The handle makes it easy to carry, even when it’s full, and the straw lid is easy to use. It keeps her water cold for hours — like, actually cold — and she loves the look of it, which means she actually uses it. It’s not just a “school bottle” — it’s kind of her everywhere bottle now. Super modern! Big win.

Practical mom purchase that passed the teen approval test. She wants more colors now :) I’d absolutely buy it again.

ممتاز شكله كيوت مررررة و يحفظ البرودة وقت طويل

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

El termo es increíble y de excelente calidad

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.

Superb product . Good for summers as water remains cool for a longer time. Water capacity is also good
