STANLEYTough-To-Tip Admiral's Mug 20

I started using the Admiral Thermos the day it arrived, about 2 weeks ago. What a life changer this thermos has been for me. It feels like I have it forever and it has only been a few weeks. I can put my hot tea in this thermos, put the cap on, come back an hour later and have the perfect hot tea like it was just brewed. This is my dream come true; life happens; this way when I am presented with the perfect time to sit and relax with my cup of tea, it is ready.Additionally, the tip proof design is perfect for when I am snuggling under the covers with my hot brew. The thermos will always stay upright. The handle is a nice size for holding; the outside of the thermos always stays room temperature even with boiling hot water in it. Excellent design!

Stanley Tough‑to‑Tip Admiral’s Mug (20 oz) – 1‑Month ReviewAfter a month of using the Stanley Tough-to-Tip Admiral’s Mug daily—both at the office for my morning AeroPress coffee and on weekend camping trips—I can confidently say it largely lives up to its name. I’ve put this mug through its paces with hot coffee and cold water, indoors and outdoors. In this review, I’ll cover its durability, design, insulation performance, and real-world practicality to help you decide if this rugged mug is the right fit for your needs. It’s a balanced first-person take, on my experience with it.Design & Build QualityThe Stanley Admiral’s Mug in its iconic Hammertone Green finish. Its low-profile design and sturdy handle give it a distinct “outdoor” vibe.The build quality of the Mug is immediately apparent. After a month of daily use, the 18/8 stainless steel body, durable plastic, and grippy rubber bottom show virtually no wear. I’ve banged it around at the office and clipped it to a backpack while camping, and it still looks brand new. The green hammertone finish not only gives it a classic retro style (I’ve gotten multiple compliments on its cool “navy mug” look here in Norfolk, VA), but it will also hide scratches and dirt well. The handle is solidly attached with metal screws and feels secure when carrying a full 20 ounces. (One small nitpick: the handle screws use a star-shaped key instead of a standard Phillips head, so you’d need a special screwdriver if you ever had to tighten them. It hasn’t been an issue for me, but it’s worth noting.) Overall, the design balances ruggedness and style – it looks like it belongs on a ship or a campsite, yet it’s right at home on my desk too!Stability & Spill-Proof PerformanceStability is where this mug truly shines. The lower center of gravity base and non-skid rubber pad on the bottom make it extremely hard to tip over accidentally. I have tested to try and casually knock it over at my office desk, and even when I bumped the table, the mug stayed put. In the car, it sits nicely on the console or dash – during sharp turns and sudden braking, it does not budge. (It’s almost entertaining to see a mug not sliding around where everything else would!) The trade-off for the wider base is that it won’t fit in any standard car cup holder, so you’ll need to place it on a flat surface instead. However, given how securely it grips, it is a non-issue, I don’t mind this much except on long drives with passengers.The spill-proof lid is a big plus. The mug has a locking flip-top lid that seals tightly. I can toss the mug in my bag or hold it upside down without any leaks – not a drop escapes. This has saved me from coffee disasters more than once when I’ve knocked the mug over (again, hard to do but not impossible) or had to stash it in my lunch bag. When you want to drink, you just flip the lid open to sip. The hinge keeps it back securely, so it doesn’t flop down on your nose (a pet peeve with some people I am told). One thing to remember: you do need to fully snap the lid closed to make it leak-proof. This should be obvious – but that’s true of any spill proof travel mug. Overall, for stability and spill prevention, I couldn’t ask for better performance. It truly delivers on the “tough-to-tip” promise, lets me be confident knowing I’m unlikely to wear my coffee or water on my shirt.Insulation PerformanceBeing a Stanley product with double-wall vacuum insulation, I had high expectations for heat and cold retention. In practice, the insulation is good but not mind-blowing. Here’s what I noticed between hot and cold retention:Hot Coffee: My morning coffee stays satisfactorily hot for around 2–3 hours before dropping to a warm (but drinkable) temperature. If I preheat the mug with boiling water (like the instructions suggest) and keep the lid mostly closed, I can push close to 4 hours of reasonably hot coffee, which aligns with Stanley’s claims. However, on days when I’m sipping frequently and opening the lid a lot, I notice the coffee cooling off faster, around the 2-hour mark it’s merely warm. For a premium mug at this price, I expected better heat retention. It’s not poor by any means – it covers my entire commute and morning routine – but by lunchtime my coffee is usually cold. If you need all-day piping hot coffee, you may be a bit underwhelmed.Cold Water: On the flip side, the mug excels with cold liquids. I fill it with chilled water (no ice) and it stays refreshingly cold for 3+ hours with only a minor temperature rise. On an afternoon at my desk, my water remains cool well into mid-day. During a camping trip, I dropped in a few ice cubes – and incredibly, there was still ice rattling around after 6 hours in moderate outdoor heat. So for keeping drinks cold, it performs great. The mouth is wide enough that it is easy to add in normal sized ice cubes.The insulation will keep coffee hot through a commute plus a morning rutene at the office or a morning of moving camp stuff, but don’t expect your drink to stay steamy hot all day. Cold drink performance is stronger, especially if you use ice. Given the mug’s bulk and price tag, the heat retention is a hair below what I hoped, but it’s acceptable for everyday use. It’s on par with many other vacuum mugs, just short of the highest-end thermoses.Practicality in Daily & Outdoor UseOne thing I love about this mug is how versatile it is throughout my day. In the morning, I brew my AeroPress coffee straight into the mug – the opening is perfect for it, and I don’t have to transfer from a smaller cup. Once the coffee is done, I give a quick rinse and it becomes my water mug for the rest of the day. It’s great not having to switch cups; this single mug handles my whole day at the office very well, saves me from bringing a coffee mug and a water thermos to work. Also, the stainless steel interior doesn’t keep flavors, so my water doesn’t taste like coffee oils at all (as long as I give it a quick rinse).At the office, the Admiral’s Mug has proven to be incredibly practical. The handle makes it easy to carry along with my laptop or notebook when I’m moving between rooms. It is a bit wider and heavier than a typical tall travel mug (you can feel the solid 1.2 lb build), it is still comfortable to hold and drink from. The low center of gravity means I’m far less worried about accidental spills at my workspace. In fact, a co-worker joked that I finally “child-proofed” my coffee. Little quality-of-life features, like the dishwasher-safe design, sound great but in the sintructions it does indicate that washing it in the dish washer will wear it more quickly then hand washing (especially if you have art or desgins on it) I personally just hand wash it, which is very easy to do! The mouth is wide enough for a normal hand to scrub the inside if nessary. I find this mostly unessary though as things nearly glide off the intieror with light cleaning and rinsing. I would say that it is perfectly practical to hand wash the mug exclusively, but if you absolutely need to clean it in the dishwasher, it does warn not to use high heat settings. Just somthing to noteOutdoors is where this mug truly feels in its element. I feel like it is truely the ideal camping coffee mug. At the campsite, I can set it on a rock or fold out chair that isn’t perfectly flat, and it won’t tip over even if bumped. The sturdy handle is great for clipping the mug to a backpack or hanging it on a branch. I also appreciate the large handle opening; it’s roomy enough to grab comfortably even when I’m wearing gloves. The mug’s durability gives me confidence – I don’t have to baby it. It can tumble around in the back of a truck or get stolen by a child off a camping chair without catastrophe (no dents or cracks so far). Its practical benefits really shine when you’re in the field: you can trust it to keep your drink secure and relatively temperature-stable while you focus on other things.A minor inconvenience when traveling with it: as mentioned, it doesn’t fit in cup holders, and its wode bulk makes it a little less portable in tight spaces, but also, it is much shorter than most tumbelers. On a road trip, I had to place it in my car’s center console area, which was fine, but not as neat as a slim travel tumbler in a cup slot. So if you primarily need a car mug, that’s a consideration. For walking, camping, desk use, etc., it’s fantastic – just grab it by the handle or even toss it in a bag; it won’t leak. And those admiring comments from friend campers or coworkers about the vintage look are a sweet bonus.Pros:Ultra-Stable Design: Wide base and rubberized bottom prevent tipping on almost any surface. It stays put on desks, dashboards, boat decks – you name it. Great for those who know they are accident prone!Spill-Proof Lid: Leak-resistant flip lid locks securely, truly preventing spills when closed. You can carry it in a bag or knock it over without worry.Durable Build: Rugged stainless steel construction with quality plastic/metal parts. Survives daily use and outdoor adventures with no damage. (Plus it’s very easy cleaning.)Excellent Cold Retention: Keeps water and cold drinks chilled for hours. Great for staying hydrated on hot days; ice lasts impressively long.OK Hot Performance: Will still keep this as a Pro, becuase while other priumum insulated mugs perform better. It still keeps coffee hot for a couple of hours and drinkably warm for up to ~4 hours (which is still great performance just less than expected), which covers your morning routine and commute easily. But a bit underwhelming for a premium mug.Comfortable Handle: Large, sturdy handle is easy to grip, even with gloves. Makes carrying and drinking one-handed very convenient.Wide Mouth: Easy to fill, fits an AeroPress for brewing coffee directly, and accommodates full-size ice cubes. Also easy to clean inside thoroughly.Stylish & Distinctive: Classic Stanley Hammertone Green finish and retro jug-like shape stand out. It has a cool “navy ship mug” vibe that gets compliments.Cons:Too Wide for Cup Holders: The great wide base won’t fit in standard car cup holders. It’s stable on flat surfaces in a vehicle, but not ideal for every car ride.Bulky Form Factor: Short and stout, it takes up more desk/backpack space than a typical tall tumbler. The weight (about 1.2 lbs empty) is the trade-off for durability – not heavy, but you feel it.Handle Screws: The handle is attached with star-key (Torx) screws instead of standard screws. Not an issue unless you need to tighten or remove it, a Phillips screwdriver won’t work.Premium Price: Quality doesn’t come cheap. It’s worth the ~$30 price for what you get, but it’s an investment for a mug. If you’re on a tight budget, there are cheaper mugs (albeit far less sturdy) out there.Conclusion & Recommendation:In my experience, this mug has proven to be a reliable and rugged daily companion. Its stability and spill-proof design have literally saved my coffee (and my cloths) on multiple occasions, and its durability gives me confidence to take it anywhere—be it the office, the car, or wherever outdoors. Yes, it has a few limitations (it’s not car-cup-holder friendly, and the heat retention, while solid, isn’t the very best in class), but those feel minor in comparison to how well this mug excels in practicality and build quality.If you’re looking for a nearly indestructible, tip-proof mug that can double as your go-to office coffee cup and your camping buddy, the Admiral’s Mug is a fantastic choice. It brings together the convenience of a travel mug with the sturdiness of an insulated camp container. I personally love it and use it every single day. Overall, I highly recommend this mug for anyone who wants durability and stability in their travel cup. It’s a specialty mug that absolutely delivers on its promises, and it might just be the last coffee mug you ever need to buy. Cheers! ☕️

The Stanley brand is simply one of the best in the market. I bought the black and shortly I will buy the green. It is a very sturdy Mug and it attracts a lot of comments from friends. It is easy to clean. Keeps my drinks cold or hot for a very long time. My only suggestion to the company is to look at the possibility of introducing other bright colors. How about Purple, Yellow, Red, Coral.

This has become my "Go-To" desk coffee mug.It keeps stuff really hot or really cold as you like. It is practically impossible to accidentally spill this mug, you'd have to place it on a bad surface. Rugged, the bottom stays put, wide mouth makes it easy to clean, it is well-balanced for carrying even with an armful of items. I'd be hard-pressed to go back to a regular mug now. I hear some folks say the Stanley mugs are expensive...quality and performance are relative. I feel like the two I purchased were cost-effective investments. If you want a quality mug that performs, this is your target right here. I should mention that I've also purchased them for my daughters for school and other pastimes.

I love my Stanley stein, so I figured this would be as good. The look and feel is Stanley which I like but this mug has a few things I think are design flaws. The first is that I can only fit 3.5 fingers in the handle instead of my whole hand, I'm 6'4" and have a medium to large hands and it doesn't bother me much but would feel better if the handle was larger to accommodate the width of my whole hand. The second flaw is the rubber around the lid (see photo) is too tight and is very hard to close and open because of that. It's leak proof but tolerances there are off. Also due to that it's likely tiny bits of the seal plastic are rubbing off ending up in my drink. The third is the the flip lid doesn't lock down when open. It pushes flat when open and would be nicer if it stayed there, instead it typically rises up slightly to ~45° and this part sometimes bumps my nose. Overall though, I love the look and feel of this and it's easy to clean. A nice wide base with the bottom grip makes it nearly unstoppable and provides a good volume for the beverage. All in all, Id recommend it but also hope Stanley could make a few slight improvements on the design to make it even better.

What can I say - it holds coffee and keeps it warm! I bought it for the office so I can slap this bad boy down on my desk with zero tip over risk. And let’s be honest, it has old school good looks.

It's enormous and quite stable. I haven't spilled my coffee on my keyboard (again) since I got it. Holds heat well. The handle is a bit small for my hand but that's not a major problem.

Bought this cup for my husband and he was initially not impressed simply because he makes fun of my Stanley cups. However, this has quickly become his favorite and most used coffee mug. It holds a surprising amount, its wide base makes it very sturdy, and the tight latch on the lid allows it to travel well. My husbands only complaint is that the base is too wide to fit in a cup holder - but the grip on the base is impressive and he hasn’t had any issues with it riding on his console.
