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

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 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.

I LOVE it!! This tumbler is HUGE! I ordered the 40oz as it was a better deal and I dont have to keep running back to the fridge for a refill. It is a super pretty green, leak proof, and fits in my car cup holder. The quality is great, if not better than those "trendy" Stanley cups.. I will never buy another brand. Forever customer 🤝

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.

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!

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.

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)
