Our little Hydroflask family is growing! It started with the orange 21 oz Standard Mouth Insulated Bottle that I bought about 5 or 6 years ago. This has served as my wife’s gym bottle and my “light cragging” water bottle quite well. I then bought my 40oz Tall Boy, which has carried everything from ice water for relaxing on the beach in the summer to hot mulled apple cider for Fall/Winter day hikes. A couple of years ago I picked up a first generation food flask (far left) which kept soups and chili’s hot while winter climbing on Mount Washington and ice climbing in Crawford Notch. Just recently Hydroflask sent me their updated version of the 12 oz Food Flask and a 16 oz Insulated Coffee Flask to review.
So what makes Hydroflask different from all the other water bottle/tumbler companies out there? Well that would be the TempShield™ double walled vacuum technology that keeps drinks hot or colder longer than the competition. I wanted to try to quantify this statement with a little informal testing. Granted this is not some “double blind” research but it illustrates the point. First test…
Keeping Hot… Hot
I had experienced it many times before finding my coffee or tea still piping hot 4-5 hours into a sub-zero climb on Mount Washington. More recently I’ve used the Food Flask to keep soup & chili hot for a mid-day hot lunch sans stove while ice climbing or back-country skiing. To illustrate this I added just boiled water to a room temperature 12 oz Food Flask.
I then placed this in my freezer at -10°F (-23°C) for about 4.5 hours.
Impressively the water temp was still quite hot. In real life practice you can get better results then this when using the Hydroflask for food or drink. First, you can “pre-heat” the container by filling it with boiled water while heating up your food or drink separately. Then dump the hot water and immediately put your hot drink/food in and seal the container. Second, the container gets even more insulation when carrying it in my backpack surrounded by puffy insulating layers of clothing. Finally, if it’s a hot meal like chili or soup I tend to not open it until I want to consume the whole container (lunch time). Having it open for only a few minutes in arctic temperatures and moderate winds will see stored heat quickly lost!
Keeping Cold… Cold
I have also discovered that this much insulation can keep my ice in solid form for multiple pours of a refreshing beverage while hitting our local little pond beach or a town music festival. It’s almost hard to believe how effective these can keep ice. For this informal experiment I packed the same room temperature 12 oz Food Flask with ice from our freezer, sealed it, and sat it on our kitchen table overnight. We are currently burning wood so our house is sitting around 70 degrees (yay shorts in the winter).
Around 1:30 pm the following day (19.5 hours later) I remembered I was doing the experiment, moved it to the kitchen counter, and opened it.
I’m confident that if I reran this for 24 hours there would still be some water in frozen form at the end of the 24 hours! So how does Hydroflask insulate so well? It comes down to their patented TempShield™ technology. I spare you the nitty gritty and just say that not all “double walled” constructions are created equal. If you are interested in some of the finer details you can read about it here.
Finally of note with this updated 12 oz Food Flask is the more rounded “pill shape” design and leak-proof design. This packs in my smaller ice climbing packs quite well and I haven’t had a single leak during over fifty miles of trail and thousands of feet of climbing.
I also have to say I love finding products that not only work well for my family but are made by companies committed to giving back, especially when it comes to our natural resources! Through “Parks For All” Hydroflask is currently providing over $110,000 in grants to help protect, restore, and provide access to various park projects. You can learn more here.

I’m not a surfer, but I have quite a few friends (and one kick ass niece) who is, so you surfer types can read up on what this is all about here.
Hydroflask stands behind their products with an excellent warranty. It’s not a “drop it off a thousand foot cliff get a new one” type warranty (I’m personally glad those types of warranties are becoming a thing of the past) but one that truly stands behind the craftsmanship yet maintains a slight bit of realistic expectation. You can read the full details here.

First off you should know of the 5 Hydroflask models I’ve talked about the updated 12 oz Food Flask and 16 oz Insulated Coffee Flask were provided by Hydroflask to review. The other three models pictured in the first pic were purchased with my own money. Getting a couple samples has not influenced my opinion on these items in any way!
Second, Hydroflask has already started offering free Holiday Shopping on all orders, no minimum purchase! You can find the daily code for free shipping at the top of Hydroflask website. Then you can also enter “ALPINESTART18” in the cart and get an extra 10% off your order (minimum order of $20). The free shipping and 10% off codes work together! I just tested it to buy myself a 16 oz Insulated Coffee Flask since the purple one they sent me works better for my wife!
A water bottle or coffee mug is such an essential for our daily lives. Once you start using a quality one from a company like Hydroflask you quickly realize that design matters. Whether replacing that old funky plastic gym bottle or realizing you can have hot soup 4000 feet up a winter climb without firing up the stove there is most definitely a Hydroflask model that would be a nice addition to your kit (or your friends & family’s kits). These make awesome holiday gifts and as such will be included in my 2018 Holiday Gift Guide coming out at the end of the month. Thanks for reading!
