Hydro Flask
12 Oz Insulated Mug
The Hydro Flask 12 Oz Insulated Mug is a double-walled stainless steel travel mug with TempShield insulation that keeps beverages cold for 24 hours or hot for 12 hours, making it suitable for coffee, tea, or cold drinks at home, work, or while commuting. It holds 354 ml (12 oz), measures 8 cm by 11.5 cm, and includes a handle and a lid with a sliding sip cover; the manufacturer describes the lid as watertight, but many user reviews report it is not fully leakproof, so upright transport is recommended. This BPA-free mug is hand-wash only and should not be used in a microwave or freezer, and some owners note the exterior coating may wear over time.

Product Insights
The Hydro Flask 12 Oz Insulated Mug is a 34 CAD desk and kitchen-counter mug whose case rests on vacuum insulation and drinking feel rather than travel-grade containment: TempShield holds coffee hot for over an hour, still warm at 2 hours and near 130°F at 3.5 hours, keeps cold drinks below 50°F for 6+ hours, holds coffee above 50°C to preserve roasted and bitter notes, and keeps the handle cool even with boiling liquid inside, against ceramic and uninsulated baselines that lose heat far faster. Physical character is ceramic-mug-like at about 335 g empty, with a broad flat base that sits planted, a wide C-shaped handle and soft-touch coating for a secure full-hand grab and one-handed carry, and a rim thinner than typical insulated tumbler lips so it drinks like a regular mug. Construction is bare 18/8 pro-grade stainless inside, adding no metallic taste or flavor transfer, with a molded interior fill line that makes the full 12 oz the usable capacity below the press-in lid; the exterior is a powder coat over the soft-touch layer in four colourways (Black, Pine/Bottle Green, Indigo/Dark Blue, Dusky Pink), one size, 34 CAD each, in stock. The tradeoff is durability, sealing and portability: the lid is splash-resistant, not leakproof, and leaks if tipped or packed in a bag; the 3.25 in base does not fit most car cup holders under 3 in; micro-scratches trap coffee oils over time so non-abrasive hand washing keeps taste neutral, and hand washing is recommended regardless because dishwasher cycles risk the finish and the lid slider traps residue, while dishwasher heat, hot soaking and harsh scrub pads degrade the soft-touch finish; buyers report the rubbery coating can wear or peel, less durable than competitors such as Yeti; and with no inner support behind the vacuum wall a knock dents it where a solid mug would not, so its 335 g heft is fine for a commute but a burden on a long backpack carry. Coverage is thin at 5 reviews.
Verified claims
- Heat retention
- Coffee stays hot for over an hour and is still warm at 2 hours; it is near 130°F at the 3.5-hour mark.
- Cold retention
- Cold drinks stay below 50°F for 6+ hours.
- Insulation
- Vacuum insulation loses about 1-2°C per hour; a ceramic mug drops boiling water below 60°C in 45 minutes.
- Flavor retention
- Holds coffee above 50°C to keep its roasted and bitter notes.
- Heat isolation
- TempShield insulation keeps the handle cool even with boiling liquid inside.
- Spill resistance
- The press-in lid is splash-resistant, not leakproof, and leaks if tipped or packed in a bag
- Fill line
- Interior fill line prevents overfilling; the full 12 oz stays usable below the lid
- Cup holder fit
- 3.25 in diameter base; does not fit most car cup holders (<3 in).
- Stability
- Broad flat base sits planted on desks, tables, and picnic tables
- Lip feel
- Rim is thinner than typical insulated tumbler lips, so it drinks like a regular mug.
- Handle grip
- The wide C-shaped handle and soft-touch coating allow a secure full-hand grab and one-handed carry, making it practical to hold while commuting or moving around.
- Weight
- About 335 g empty, roughly the heft of a home ceramic mug.
- Taste
- The bare 18/8 pro-grade stainless steel interior adds no metallic taste or flavor transfer.
- Flavor drift
- Micro-scratches trap coffee oils over time; a non-abrasive hand wash keeps the taste neutral.
- Cleaning
- Hand-wash recommended: dishwasher cycles risk the finish, and the lid's slider traps residue.
- Coating
- Buyers report the rubbery coating can wear or peel with regular use and is less durable than competitors like Yeti.
- Finish care
- Dishwasher heat and harsh scrub pads degrade the soft-touch finish; cleaning by hand with warm water, mild soap, and a non-abrasive cloth preserves it.
- Dent resistance
- No inner support behind the vacuum wall, so a knock dents it where a solid mug would not.
- Usable capacity
- The 12 oz (354 ml) is usable capacity, set by a molded interior fill line.
- Everyday use
- Desk and kitchen-counter mug; a buyer reports coffee still hot to the last sip on a car trip.
- Portability
- Empty, it carries ceramic-mug heft: fine for a commute, a burden on a long backpack carry.
- Material
- Bare 18/8 pro-grade stainless lines the inside; the color is a powder coat bonded to the exterior.
- Colour options
- All four colourways — Black, Pine/Bottle Green, Indigo/Dark Blue, Dusky Pink — come in one size at 34 CAD each.
- Replacement lid availability
- The press-in slider lid is sold separately as a replacement part, so the mug's most common wear point can be replaced rather than replacing the whole mug.
- Mouth opening access
- The roughly 3.5 in (8.9 cm) mouth is wide enough to drop in standard ice cubes and reach the full interior with a bottle brush for hand-washing.

Sipping your morning coffee at a relaxed pace
The 12 oz capacity suits a standard brew, and per customer reviews the mug has the familiar feel of a regular mug with a comfortable handle and lip. Its TempShield insulation keeps coffee hot while you get ready — one commenter says it lets you take your time drinking, with the option to take the lid off if you want the coffee to cool faster. Hand-wash only.[3,4]
Keeping drinks cold through the day
This 12 oz insulated mug is meant for enjoying cold beverages over long stretches—per the merchant, its TempShield technology keeps drinks cold for up to 24 hours. One care note: the mug should not go in the freezer. Care instructions also say not to microwave it.[3]
Warm drinks on drives to the course or countryside
Bring the Hydro Flask 12 Oz Insulated Mug along on car commutes to outdoor activities like a round of golf or a country trip. Per a summary of customer reviews, it fits the cup holder and stays hot on the drive, with reviewers reporting a warm sip even after hours. Note this reflects an analysis of reviews rather than the original customer comments.[3]
Toting coffee in a bag on the go
With its watertight lid and easy-to-tote handle, this insulated mug is geared toward carrying your drink in a bag or on the move — one commenter says it feels secure in a bag, and a reviews analysis ties the leakproof lid to spill-free travel in bags and on car seats. Experiences vary, though: another customer found it not spill proof, and the same commenter noted the lid only came off once when the mug was dropped on concrete, leaving just a small nick.[1,3,5,6]
Desk-side coffee during the workday
Keep this 12 oz insulated mug at your office desk for coffee or tea while you work. Reviewers report the leakproof lid helps protect the desk from spills, the size suits desk use, and the handle makes it easy to grab between tasks.[3]

| 12 Oz Insulated Mug: Choose this if you want a 12 oz (354 ml) double-walled stainless steel mug that keeps drinks hot for up to 12 hours or cold for up to 24, with a watertight closeable lid for bag or car-cup-holder use and a comfortable C-shaped handle with a soft-touch exterior. It suits desk, commute, and morning-routine drinking, with a lid you can remove to let coffee cool. Note it is hand-wash only (never microwave or freezer), and some owners find the lid awkward to remove and wash and report the rubbery exterior coating wearing over time.[2,3,4,5,6,7,8] | Wide Mouth 16 Oz Insulated Coffee Bottle: Choose this if you want a compact 473 ml (16 oz) coffee bottle for daily commutes: its BPA-free double-walled stainless steel body with TempShield insulation keeps drinks hot for 12 hours or cold for 24 hours, and the wide mouth plus dishwasher-safe design make filling and cleaning simple. It comes in Black, White, Pine/Bottle Green, and Pink, each with a screw-on wide-mouth lid with a flexible strap handle, and is backed by a lifetime warranty. One owner of this 16 oz bottle notes the lid is low-maintenance to clean, though it is fine to leave washing until the end of the day.[9,10,11,12] | Wide Mouth 20 Oz Insulated Bottle: Choose this if you want a mid-size 20 oz (591 ml) insulated bottle for everyday bags and cup holders: its double-walled, BPA-free 18/8 stainless steel body with TempShield keeps drinks cold up to 24 hours or hot up to 12, and the wide opening fits ice cubes. A watertight lid, carry handle, and color options including black, green, indigo/dark blue, and pink suit commuting and workouts. Note that while the retailer lists it as dishwasher safe, one care source advises against dishwashing because heat can affect insulation and discolor the powder coat, and the bottle should never go in the microwave or freezer.[13,14,15] |

Coffee staying hot
Great cup for keeping my coffee hot in the car as I head out for golf course or trip to country. Coffee hot enough to last sip !
Love this mug
Perfect size for morning beverages keeping drinks hot.
Tasse à café
Idéal pour mon travail, grosseur idéal et fini les cafés froids!
Excellent Purchase
This cup keeps your coffee HOT! I use it everyday and it keeps my coffee HOT for over an hour. Even after 2 hours, my coffee is still warm enough to enjoy. I like the style of a cup with a handle and the lip isn't overly thick like some insulated mugs. No regrets on this purchase.
Reddit Insights
4 threads · r/BuyItForLife, r/Hydroflask, r/CoffeeReddit users have mixed feelings about the Hydro Flask 12 oz insulated mug: many praise its excellent heat retention and sturdy build, but common complaints include a non-leakproof lid, rubber coating wear, and occasional defective units.

Compared To

Yeti is often preferred for its dishwasher-safe, leakproof mag slide lid and better lid durability, though Hydro Flask wins on aesthetics and lighter weight for some.
vs Klean Kanteen
Klean Kanteen is praised for longevity and easy cleaning, but Hydro Flask's rubber grip and design appeal to some users.
vs Zojirushi
Zojirushi offers extreme insulation that some find overkill; Hydro Flask is more balanced for coffee drinking.

Hydro Flask coffee mug secure but lid annoying
I like my hydroflask coffee mug, but the lid is kind of a pain to take off and wash. It definitely feels secure in a bag though! It’s only ever lost the lid when dropped on concrete while running for a bus, and only has a small nick.

Hydro Flask coffee mug not dishwasher safe and coating wears
I like it, but I feel like there’s better cups out there. It’s not dishwasher safe or spill proof. The rubbery stuff on the outside doesn’t seem to be lasting that well on mine, when compared to the powder coat of my water bottle.

Mug should keep coffee hot; counterfeit/faulty units exist
