Sidagar Super Ice King 1000ml Triple-Lid Vacuum Tumbler - 12Hr Insulation, 316 Stainless Steel, Ceramic Coated, 3-in-1 Straw/Direct/Sip Lid

First off, it is stainless steel inside with double wall construction for long lasting hot or cold beverages. The handle is very comfortable and a wrist lanyard with quick release is included. It is a large container holding 32 oz. of your desired drink.

The top is intuitive in that you have options when drinking. If you unscrew the small cap on top, you drink from a straw. If you press the release on the top, the lid hinges open to allow drinking or sipping from the small opening like most cups. The straw is inside the container and attached to the top. One little or big extra depending on the person, is a small white "basket" that wraps around the internal straw and allows the steeping of tea if desired. I'm sure the infusion folks will use it to infuse various citrus flavors into their water. The basket pops out with a small twist so you can clean it thoroughly.

It will not leak in my testing. With everything screwed down, leaking is non existent. The only hard part was getting the adhesive off the see through lid that remained after a warning sticker is removed alerting you to the fact that hot liquids can burn you. I tried soap, then some olive oil and finally rubbing alcohol to remove the sticky residue. I'm sure that packaging requirements dictate these stickers and placement. It comes with many things is seems.

I tried to picture all the features. I believe it is the next best hydration idea to come along.

I think this tumbler is super bulky, but I do like it. It has a silicone bottom which is great. The handle has a nice grab to it and keeps my water super cold all day. Sometimes I still have ice in it the next day. I gave it four star because the lid is made a big awkward. I haven't figured out exactly the best way to clean it yet. It is different than any lid I've ever used. I love that I can screw a lid over my straw so that it doesn't leak at all. Very nice!

I thought this would be my new go everywhere cup but unfortunately it's too big for my 2018 Chevy Equinox cup holder. That being said, I love everything else about it. The straw is plyable, but falls into place easily round my ice. It has s cover that protects the top of the straw attached to the lid. You also,have the option to flip the lid open to pour. I do have to hold the loop out the lid comes down and gets you. The handle is nice, stylish, though may get a little uncomfortable if carrying a full cup for longer periods. Also, when full of water & ice, this cup is heavy. I appreciate the rubber bottom, isn't scratching or banging the surface when,put down. This cup is sturdy and hope it will last a long time.

This 32‑oz Sidagar tumbler is a workhorse. The 316L stainless interior and vacuum insulation actually perform, my coffee was still hot after an eight‑hour shift. Cold drinks stay frosty just as long. The form factor is clever—chunky yet tapered enough to drop into a standard car cup holder, and the side handle is solid, not a flimsy bolt‑on.

The lid and straw are the stars. It unscrews and stays tethered with a short rubber piece, so you’re not juggling parts. Inside is a full-length, rubberized straw that reaches the very bottom—not a wasted ounce lurking under the tip. Screw the cap back on and it seals the straw tight, flip the lid open, and you can sip without the straw, if the drink’s too hot. I shook it, tipped it, tossed it in a bag, but no leaks.

Little touches add up: the interior’s electro-polished finish avoids that metallic aftertaste; the powder coat shrugs off scratches; and there’s an inner cage for tea leaves if you want to steep on the go.

Why it’s 5 stars: real thermal performance, leak-proof engineering, comfortable handle, versatile sip/straw options, and true cup‑holder compatibility. I can’t find a meaningful flaw—just be ready for the size; it’s big by design.

Bottom line: If you want one bottle that carries a day’s worth of hot or cold drinks, and won’t betray you in the car, or your bag, this is it. I will recommend this product to friends and family.

I've become OBSESSED with Sidagar refillable bottles because, not only have they reinvented the sports bottle in completely innovative ways, but they're so pretty! So, when I saw that they came out with the the 32oz tumbler, or the "Man Mug" as I've dubbed it, I had to get it for my husband.

My husband is always on the go and has a travel cup with him. Quite often, the larger tumblers don't fit into cup holders and the no-spill lids do, in fact, leak. Not being a fan of straws, we're often limited in our choices.

Well, this tumbler is the answer to the questions we never knew we had. You need a big cup, but are restricted to the confines of the cup holder? Boom. You prefer the security of a handle versus wrapping your hand around the entire tumbler? Here you go. You don't want to sip from a straw, but prefer to chug from the mug? Pop the lid et voila!

While not a criticism, per se, I do have one suggestion for improvement. While drinking from the tumbler, the lid will flop onto your face. So, something to keep this from happening would be great.
