I bought this because 1) it fits in my coffee machine & 2) the price & 3) the good reviews. None of which could have prepared me for just how great this mug is! It keeps my coffee hot. And I do t mean just hot, I mean HOT! And for a VERY LONG TIME! And here’s the amazing part, I’ve had mugs twice the price and they burn your hand for a few minutes while keeping your coffee warm, then cold! This thing has coffee almost to hot to drink inside it and it stays cool to the thought the entire time. You don’t even need a coaster! I only have good things to say about this. Fits 12oz of coffee and enough room to add sugar/creamer/etc…. My only question is what are you waiting for, don’t waste money on huge travel much you can’t take anywhere cause they don’t fit anywhere, and but this amazing mug that packs more bang for you buck that Starbucks! Review: Nice while it lasted :( - This was a nice mug while I had it. A few negatives right off bat would be that it can be a little hard to grip... which is what lead to it breaking. It isn't particularly heavy, the top is just rather wide and apparently a little cheap; as it completely cracked from a small drop. HOWEVER, this mug is what you would want. It keeps things nice and warm for long, it's easy to drink out of; and while I wasn't able to test it for ice, I'm sure it would hold fine. ## Features - Insulated 20 oz Coffee tumbler: Double-wall vacuum insulation technology, keep drinks hot for over 6 hours and cold for around 24 hours, sweat proof, no condensation - Premium Material: Made from high quality 18/8 304 food grade stainless steel, lead free and durable, never rust, easy to wash and unbreakable - BPA Free Sliding Lid, Spill Proof: Silicone gasket seals, drinking hole on the top for easy sipping, straw friendly - Car Cup Holder Friendly: Great for on the go, camping, gyms, outdoor activity - Superior Powder Coated: Multi-color option, durable finish, no scratching, no peeling or fading, easy grip, long lasting ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07MV6Z896 | | Age Range Description | Adult | | Best Sellers Rank | #388,524 in Home & Kitchen ( See Top 100 in Home & Kitchen ) #12,018 in Glassware & Drinkware | | Brand | SUNWILL | | Capacity | 20 Fluid Ounces | | Colour | Powder Coated Navy Blue | | Country of Origin | USA | | Customer Package Type | Gift Box | | Customer Reviews | 4.4 out of 5 stars 3,187 Reviews | | Enclosure Material | Stainless Steel | | Finish | Powder Coated | | Included Components | Lid, Tumbler | | Is the item dishwasher safe? | Yes | | Is the item microwaveable? | No | | Item Dimensions W x H | 8.6W x 17.1H Centimeters | | Item Type Name | tumbler | | Item Weight | 0.72 Pounds | | League Name | ncaa | | Manufacturer | SUNWILL | | Material | Stainless Steel | | Material Features | Insulated | | Material Type Free | BPA Free | | Number of Items | 1 | | Occasion | Anniversary, Birthday, Engagement, Wedding | | Other Special Features of the Product | Microwave Safe | | OutputCapacity | 20 Fluid Ounces | | Pattern | Solid | | Product Care Instructions | Dishwasher Safe | | Product Style | Modern | | Recommended Uses For Product | Home, Office, Travel | | Reusability | Reusable | | Shape | Round | | Size | 20 Ounces | | Special Feature | Microwave Safe | | Specific Uses For Product | Cold Drinks, Hot Drinks | | Style | Modern | | Subject Character | Navy Blue | | Team Name | mit | | Theme | Sports | | UPC | 670924518426 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** SUNWILL - **Capacity:** 20 Fluid Ounces - **Colour:** Powder Coated Navy Blue - **Included Components:** Lid, Tumbler - **Material:** Stainless Steel - **Recommended Uses For Product:** Home, Office, Travel - **Special Feature:** Microwave Safe - **Specific Uses For Product:** Cold Drinks, Hot Drinks - **Style:** Modern - **Theme:** Sports ## Images ![SUNWILL 20oz Tumbler with Lid, Stainless Steel Vacuum Insulated Double Wall Travel Tumbler, Durable Insulated Coffee Mug, Powder Coated Navy, Thermal Cup with Splash Proof Sliding Lid - Image 1](https://m.media-amazon.com/images/I/71zOc2syy3L.jpg) ![SUNWILL 20oz Tumbler with Lid, Stainless Steel Vacuum Insulated Double Wall Travel Tumbler, Durable Insulated Coffee Mug, Powder Coated Navy, Thermal Cup with Splash Proof Sliding Lid - Image 2](https://m.media-amazon.com/images/I/811pzWik5-L.jpg) ![SUNWILL 20oz Tumbler with Lid, Stainless Steel Vacuum Insulated Double Wall Travel Tumbler, Durable Insulated Coffee Mug, Powder Coated Navy, Thermal Cup with Splash Proof Sliding Lid - Image 3](https://m.media-amazon.com/images/I/71zb4A8bWFL.jpg) ![SUNWILL 20oz Tumbler with Lid, Stainless Steel Vacuum Insulated Double Wall Travel Tumbler, Durable Insulated Coffee Mug, Powder Coated Navy, Thermal Cup with Splash Proof Sliding Lid - Image 4](https://m.media-amazon.com/images/I/71MsHA+czSL.jpg) ![SUNWILL 20oz Tumbler with Lid, Stainless Steel Vacuum Insulated Double Wall Travel Tumbler, Durable Insulated Coffee Mug, Powder Coated Navy, Thermal Cup with Splash Proof Sliding Lid - Image 5](https://m.media-amazon.com/images/I/71GgkQwYNOL.jpg) ## Questions & Answers **Q: Looking for a mug with a secure lid that doesn't leak....has anyone who has purchased this cup had issues with leaking?** A: I hope someone talked you out of this mug. The lid does NOT screw on, so when a hot beverage is in the mug, steam builds up (because you have the lid all closed to prevent spillage) and bam! Off flies the lid spilling very hot drinks! With cold drinks there is no problem. The lid is secure. In fact it is hard to remove unless you open the drinking part for air to release the suction! **Q: How many ounces of liquid will the 20 ounce tumbler actually hold?** A: It holds only 16 ounces! With the lid in place, 16 ounces of liquid comes right up to the bottom of the lid. I did measure it with a measuring cup (twice) just to be certain. It will hold 20 ounces only if you fill it right to the rim. This seems to be the case with EVERY stainless steel insulated tumbler available for sale under every brand I have tried, and it's very aggravating. I'd like to find an insulated tumbler that actually holds 20 oz. with the lid on! **Q: Does this have a non slip silicone base?** A: No it does not but I like the cup. **Q: Do yeti lids (with the magnet slider) fit this tumbler?** A: The Yeti mag lids do fit this tumbler. I prefer the magnet lid as its easier to clean. You can purchase separately (either Yeti or generic). I bought the generic lid and it’s identical except it doesn’t say YETI on the magnet. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Amazing, great size, great mug! *by D***. on 28 May 2026* Wow, just wow!

Because I get too excited when I get something and then later on it's not as good as I thought. First of all I'm going to say this cup keeps my coffee hot all the while in drinking it, usually i make my coffee at 4:00am before I go to work and it's hot by the time I'm done with it like around 7:00 or 8:00 the only thing that you have to be aware of with this cup is the lid. Make Sure the mouthpiece is open when you're closing it on the cup love the cup so good that I bought a second one ## Frequently Bought Together - SUNWILL Travel Coffee Tumbler 20 oz, Insulated Mug with Lid, Stainless Steel Cup for Outdoor, Powder Coated Navy - Huron Vacuum-Insulated Stainless Steel Travel Mug, 16oz Licorice - Leak-Proof Lid for Hot/Cold Beverages, Fits Most Cup Holdersand Brewers --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/419056911-sunwill-20oz-tumbler-with-lid-stainless-steel-vacuum-insulated-double](https://www.desertcart.vn/products/419056911-sunwill-20oz-tumbler-with-lid-stainless-steel-vacuum-insulated-double) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-06-05*
