Tool Review: Zojirushi Stainless Steel Mug

Designer/Artist William Morris once said, “Have nothing in your house that you do not know to be useful, or believe to be beautiful.” My Zojirushi stainless steel mug is one of the few things I’ve ever owned that I feel truly meets both of these criteria.


The design, materials, manufacturing and workmanship of the mug are nothing short of outstanding; the aesthetics and heft in the hand are truly fantastic. I really could not want for more out of such a product. I love looking at it, I love holding it, and I love using it.

I hope one day to come back and write a review worthy of how truly great this travel mug is, but for now, suffice it to say that I’m in love. I spent a LOT of time reading reviews on Amazon and elsewhere, and searching stores and vendors to find the best thermos/mug on the planet and settled on this one. Not only is it easy and intuitive to take completely apart and wash thoroughly (too many I’ve come across are impossible to take apart and clean properly, if at all), but it seals completely and doesn’t spill.

Even better it keeps my beverages piping hot or cold for far longer than I wish it would. There have been days that I’ve filled it with hot coffee or tea and come back several times to drink it hoping that it had cooled a bit only to find it still too hot to consume. After several rounds with this over an eight hour span, I finally opened it up and put in some ice so I could finally drink my coffee. Now I often just leave the cap open (or off) to let it cool a bit more quickly, although even this is a fairly slow process. Now I try to put my beverages in at the temperature I want to drink them knowing that that’s generally the temperature they’ll be when I get around to drinking them.

I love the fact that the cap is designed with a two stage opening mechanism (which probably won’t be noticed by most users because it’s so subtle). One pushes the button and the top opens just a few millimeters. Then letting go of the button allows the top to spring back and click neatly into place so that it doesn’t fall forward and bonk one on the nose when attempting to take a drink.

When I first came across it, I will admit I was a bit reticent at it’s relatively high price (particularly in comparison with cheaper mugs on the market, many of which I’ve tried and been highly disappointed with), but the Zojirushi is certainly worth ever penny; I would not hesitate for a moment to buy more of these.

As a small aside, I will mention that due to physics and the design of the mug that it can occasionally leak a bit when filled with carbonated beverages and then shaken. Doing this creates additional interior pressure that pushes up the internal seal mechanism on the cap that allows a small amount of liquid to escape. Beyond this small category of fluids, which I infrequently use with the mug (and I’m sure others probably won’t either), it has been absolutely airtight and worry-free.

Rating 5 out of 5 stars.

    I spent quite a while (months/years) looking at almost every messenger bag in existence (and even contemplated designing my own) for my mobile office and for weekly trips to study abstract mathematics at UCLA. I’ve been through dozens of bags (including one that could only charitably have been called a “murse”) and had problems with all of them – particularly shoulder and neck problems from carrying around so much weight. The Timbuk2 Command messenger bag ($139, medium, black) seems to have remedied all of that. My neck and shoulder pains have gone away because this bag is simply so comfortable it feels like I’m carrying half the load that I used to.
    The two length adjustment mechanisms on the shoulder strap of this bag should be a requirement for every bag on the planet. I simply don’t know how I managed without them for all this time and now I can never go back. One makes it dead simple to take the bag on and off and the other allows for additional easy length change – the combination makes the bag wear incredibly comfortably.
    As an engineer I can readily appreciate some of the very subtle design and manufacturing elements that truly make this bag a wonder. It’s not only functional and sturdy, but it’s both beautiful inside and out. Timbuk2 has certainly put some serious thought into how to make a bag. In particular the velcro strips at the top of the the flap to keep water out, the Napoleon pocket (so one doesn’t have to completely open the bag to retrieve frequently used items), the plastic strips sewn into the lining to provide additional internal structural support, and an ingenious custom pocket at the bottom of the bag for my cables and computer power brick are simply genius.
    My only minor caveats about the bag are:
    Although there are quite a number of great and useful pockets, I could do with maybe half a dozen more for daily use to keep either small items (I carry my desk in my bag) or organizing additional papers from floating around inside the bag. One can’t really fault Timbuk2 for this as it’s personal preference on my part and I haven’t seen any other bags on the market with a better designed grouping of pocket spaces for such things.
    Having a slightly larger water bottle carrier on the outside of the bag would also be excellent, but it’s nearly perfect for my Zojirushi stainless steel thermos and most small (<16 ounce) plastic water bottles. I’ll mention that one of Timbuk2’s line of Classic messenger bags includes internal water bottle pockets for those that desire something like this — or who need full waterproof interiors. The Command bag is roomy enough that I’ve also contemplated using a Camelback-type of fluid reservoir and drinking tube inside for longer day-trips.
    As a comparison, the next closest high quality bag I’ve seen in my research is Tumi’s Alpha Bravo Benning Deluxe Messenger Bag ($275). It rates incredibly high for design and beauty, but slightly lower on the functionality scale (which still makes it one of the top 0.1% of bags on the market in my mind, so if you’ve got the money, it’s definitely worth it).  It’s almost twice the price and though it’s got equivalent design touches and is made from some equivalently excellent materials with fantastic craftsmanship, it is missing some of the more interesting engineering touches including the engineering work on the shoulder strap.

    Inspiration
    This page was primarily inspired by a few posts I’d written about “What I’m Using” which in turn were inspired by LifeHacker, Supersite for Windows, and The Actor’s Studio among others. I’ve recently come across some conversation on the general topic, some of which is influenced by the Now movement.
    Below are some of these more recent sources:

    Matt Gemmell
    Jason Rodriguez
    Eddie Hinkle
    The Setup (aka usethis.com)
    The Cramped
    Aaron Parecki
    Katie Floyd
    Ryan Barrett

    I suspect I may still do annual(ish) posts like the others, but it seems interesting/useful to have a shorter aggregated page for readers to have a quicker list view of these items. In some sense, portions of the longer posts are now chunked out in my Now page which is updated a few times a month.
    Note: Some of the links on this page are affiliate links to online stores, but my goal is truly to help others rather than make a profit. The pittance I make on the site from these links generally doesn’t even cover hosting costs. If I didn’t purchase a product with my own money, it won’t be listed here. Absolutely none of these recommendations are paid placements. Manufacturers and marketers are highly discouraged from contacting me about paid placements. Readers are encouraged and welcome to share with me what they’re using. I love recommendations for awesome things.
