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

The handle is a great bonus, and the design fits perfectly in my car's cup holder, which is a big plus. It keeps my drinks cold all day thanks to its excellent insulation. One of the best features is that it doesn’t sweat at all—keeps everything dry on my desk or in my car. Highly recommend

I actually do have a Stanley. Received it as a gift. I use this and the Stanley daily. One for the gym drink, and one for iced tea or diet coke. I use them interchangebly, and performance wise of keeping the drinks cold for an extended period of time, one does not perform better than the other.The Stanley is a little wider, and I'm not a fan of the stock lid. I like the clear lid that's sold on here with the black locking sip flap and the silicone straw hole on the other side. They work well if you have a Stanley style and not a fan of that rotating piece on their lid.Speaking of lids, the Simple Modern one is fine for the most part with one annoyance. Yes, the lid itself is leak proof. Yes,if you knock anything with a straw onto its side, liquid can come out of the straw. This is not rocket science. It's just how gravity works. They do make straw caps if you're that paranoid or annoyed (take your Pic) about it.I'd say don't use the straw, but Simple Modern doesn't really give you an option with their lid, which actually isn't my annoyance. I'm annoyed the lid is so needlessly thick. It limits how much liquid you can put in it. Yes, it's not a huge difference with 40oz, but it's one reason why I do like the Stanley with the clear lid. It's kit like the lid itself is vacuum insulated so why make it so thick.And if I could make one more change to it, it would be to make detents around the top edge so you could get a better grip for taking the lid off.I like the taller and narrower design over the Stanley for most things,but mainly because if you use two cups, the spacing in the car is nicer. I haven't had issues with it tipping over. It still fits on gym equipment. In fact being narrower is nicer on some fo the precor ellipticals that only have so much ledge to them.Attached a pic of Stanley and the Simple Modern in the cup holders of the volvo xc60. You can see the Simple modern is getting pushed by the Stanley. Two SM's would be a better fit. Though it is a 2017 and a 40oz tumblers weren't a thing then. Was actually worse as the 32oz tumblers were a thing then and were wider and shorter.

This tumbler is the best! I've tried several brands, but I couldn't find one that I really liked. I love the quarter-turn lid. It is great for my arthritic hands. It keeps my drink cold overnight! The BPA-free plastic straw (it comes with 2) has a larger opening than most others and is very sturdy. With so many colors and designs, it was hard to pick just one lol. So, I'm going to treat myself to a couple more. You will not be disappointed with this tumbler!

Great tumbler, keeps hot hot and cold cold! Loved the color. Good value. Actually, we like it as well as our Yeti.

This 40oz tumbler is beautiful, easy to hold and does keep drinks cold for at least 12-15 hours but it does not hold 40oz. It only holds 34 oz when filled to the top with the lid on. The quality of the lid is good but it does leak through the base of the straw when turned over. Overall - not exactly as described…

New favorite tumbler! Love the slender size so fits into cup holders. Big straw. Easy to clean. Love that the lid is a screw top too. Color is as pictured.

use this everyday
