Short answer: Get the Zojirushi SD-KA60H (20 oz, $43.99 at Zojirushi’s U.S. store) if you want the shorter, lighter bottle for a gym bag or commute: it is 9-1/8 in tall and weighs 11 oz. Get the SD-KA75H (25 oz, $46.99) if you drink more during a workout or a day outdoors: it is rated to keep water cool for up to 66 hours vs up to 47 hours. Both are cold-only bottles with the same twist-and-push Swiftwist lid, 2 in opening, dishwasher-safe parts and 3-1/8 x 3-3/8 in footprint; the SD-KA75H is 1-5/8 in taller and about 1 oz heavier.

How we compare: every spec in this article comes from official Zojirushi pages and manuals (starting with Zojirushi’s U.S. online store and the English SD-KA manual), all listed under Sources below. We don’t run hands-on tests, and if a spec isn’t published, we say so. Last updated: October 2026.

Zojirushi is a Japanese maker of vacuum bottles, travel mugs and rice cookers. The SD-KA Stainless Cool Bottle is a 2026 line built only for cold drinks, with a new lid that opens with a short twist and closes when you push it down. In Japan, Zojirushi launched it for adults who exercise for health or as a hobby. In the U.S. it comes in four sizes, and the two smaller ones, the 20 oz SD-KA60H and the 25 oz SD-KA75H, share the same width, lid and parts. That makes the choice mostly about how much you drink and how tall a bottle your bag can take.

Specs and prices from Zojirushi’s U.S. online store (store.zojirushi.com); all three colors of both sizes listed as available, checked October 28, 2026. The U.S. cold rating is the time water starting at 40°F (4°C) takes to reach 59°F (15°C) in a 68°F (20°C) room. The 6-hour figure is from Zojirushi Japan (water starting at 4°C, 20°C room); the Fahrenheit conversion is ours. Weights are listed as 0.11 and 0.12 lb.oz by Zojirushi USA and as 0.31 and 0.34 kg by Zojirushi Japan.

Key differences at a glance

  • Capacity: 20 oz (0.60 L) vs 25 oz (0.75 L), 25% more in the SD-KA75H.
  • Cold rating: up to 47 hours vs up to 66 hours (Zojirushi USA). Zojirushi Japan rates both sizes at 9°C (48°F) or lower after 6 hours.
  • Height and weight: 9-1/8 in and 11 oz vs 10-3/4 in and 12 oz. The footprint is the same, 3-1/8 x 3-3/8 in.
  • Price: $43.99 vs $46.99 at Zojirushi’s U.S. store, so the larger size costs $3 more.
  • Same on both: cold only, Swiftwist lid, gasket-free one-piece lid, 2 in opening, all parts dishwasher safe, fold-down handle, silicone bottom cover, three colors, made in Thailand.

1. Capacity and Cold Retention

The 20 oz SD-KA60H holds 0.60 L and the 25 oz SD-KA75H holds 0.75 L. Zojirushi doesn’t give each size a use case in the U.S., but its Japanese launch release says the line comes in four sizes so you can match the bottle to the activity.

Zojirushi publishes two kinds of cold figures, and they measure different things:

  • U.S. rating, “up to” hours: 47 hours for the SD-KA60H and 66 hours for the SD-KA75H. This is the time for water that starts at 40°F (4°C) to warm to 59°F (15°C) in a 68°F (20°C) room. 59°F is cool, not ice-cold, so read it as a ceiling rather than a promise of icy water two days later.
  • Japan rating, 6 hours: both sizes keep 4°C water at 9°C (48°F) or lower after 6 hours, measured upright, filled to the line in a 20°C room.

So for a normal day, the two perform about the same on paper; the larger bottle only pulls ahead on long stretches, because a bigger volume of cold water warms more slowly. Zojirushi’s manual also suggests pre-chilling the bottle with cold water before filling, breaking up large ice, filling only to the fill line, and drinking the contents within the same day.

2. The Swiftwist Lid and What You Can Put In

Both sizes use the same lid. Zojirushi USA calls it the Swiftwist lid: it “flips open with a quick twist and securely closes when pushed down.” The gasket is built into the one-piece lid, so there is no loose ring to remove. Zojirushi calls it leak-proof when used as the manual describes. A few rules from the English manual apply to both sizes:

  • Cold only: never fill it with hot drinks, and don’t microwave it.
  • Not allowed: dry ice, carbonated drinks, dairy, fruit juice, high-sodium liquids such as soup, and drinks with fruit pulp or tea leaves.
  • Sports drinks: allowed, but clean the bottle thoroughly after each use.
  • Drinking: it is designed for drinking directly from the bottle; drinks may splash if poured. Don’t carry it by the lid cover; use the handle. Don’t drink from it while driving.
  • Lid direction: the lid unscrews in the opposite direction to the lid cover, which Zojirushi says keeps it from loosening.

If you want one bottle for hot coffee and iced drinks, this isn’t it; our Zojirushi SM-VA60 vs SM-VA72 and Zojirushi SM-KHE36 vs SM-KHE48 guides cover Zojirushi’s hot-and-cold options.

3. Size, Weight and Carrying

Both bottles measure 3-1/8 x 3-3/8 in (8.0 x 8.5 cm) at their widest, so any pocket or holder that fits one is the same width for the other. The difference is height: 9-1/8 in (23 cm) for the SD-KA60H and 10-3/4 in (27 cm) for the SD-KA75H. Empty weight is 11 oz (0.31 kg) vs 12 oz (0.34 kg). Zojirushi doesn’t publish cup-holder fit, so measure your holder against the 3-1/8 x 3-3/8 in figure if that matters.

Both have a fold-down carrying handle on the lid and a silicone cover that protects the bottom. The manual asks you to carry the bottle upright in a bag. The 2 in (5 cm) opening is wide enough that Zojirushi Japan pitches it for adding ice.

4. Cleaning and Care

Zojirushi Japan says there are only three parts to wash: the lid set, the body and the bottom cover. All three are dishwasher safe on both sizes. From the English manual:

  • Dishwasher limits: no commercial dishwashers or separate dish dryers; place the lid and bottom cover so they can’t fall onto the heating element; don’t wash the lid with its cover closed. Hand washing is recommended for longer life.
  • Body: fully washable, but don’t leave it soaking in water.
  • Don’t: boil the parts, use abrasive cleaners or scrub pads, or use bleach (Zojirushi’s own bottle detergent is the exception it lists).
  • Rust-colored spots: fill with hot water mixed with about 10% vinegar for 30–60 minutes, then rinse.
  • Lid check: Zojirushi suggests checking the lid about once a year and replacing it if it is worn.

5. Practical Costs, Price and Where to Buy

At Zojirushi’s U.S. online store, the SD-KA60H is $43.99 and the SD-KA75H is $46.99, and all three colors of both sizes were listed as available on October 28, 2026. That works out to about $2.20 per ounce for the 20 oz bottle and $1.88 per ounce for the 25 oz. The store advertises free standard shipping within the continental U.S.

The bottles aren’t electric, so the only running costs are wear parts, and both sizes share them: the Lid Set S112 is $19.40 and the Base Rubber SP3 bottom cover is $13.25, each in the three bottle colors. Zojirushi USA backs the vacuum insulation with a 5-year warranty in the U.S. and Canada.

Zojirushi SD-KA120H 41 oz / 1.2 L 12-1/2 in Up to 79 hours $49.99 3-5/8 x 3-3/4 in base; three colors

All figures from Zojirushi’s U.S. online store, checked October 28, 2026. Cold ratings use the same 40°F start, 59°F end, 68°F room test.

The 34 oz SD-KA100H and 41 oz SD-KA120H are wider (3-5/8 x 3-3/4 in) and use different lid and base parts. They make sense for a full day of outdoor work or sports; check the 34 oz SD-KA100H on Amazon. Zojirushi’s older cold-only Cool Bottle, the SD-CS50, still has a page on the U.S. store but was listed as out of stock. For a kids’ bottle with a straw, see our Thermos FUNtainer 12 oz vs 16 oz guide.

Who Should Buy Which?

Choose the Zojirushi SD-KA60H (20 oz) if you:

  • Want the shorter bottle: 9-1/8 in tall, 11 oz empty
  • Refill during the day, at the office, school or gym
  • Carry it in a smaller bag or side pocket
  • Drink it within a few hours of filling

Choose the Zojirushi SD-KA75H (25 oz) if you:

  • Drink more during workouts, hikes or yard work
  • Want the longer rating: up to 66 hours vs 47
  • Have room for a 10-3/4 in tall bottle
  • Prefer the lower price per ounce ($1.88 vs $2.20)

A View from Japan

In Japan, Zojirushi sells the line as the ステンレス クールボトル (SD-KA60 / 75 / 100 / 120, without the U.S. “H” suffix) and launched it on February 21, 2026. Its launch release says the design is aimed at adults whose exercise is about health and hobbies rather than competition, so the focus is on quick sips during activity and easy carrying. Zojirushi Japan calls the lid スマートキャップ (“smart cap”): a small turn releases the lock and the cap opens on its own when you let go, and you close it just by pushing. It sits on Zojirushi’s シームレスせん (“seamless stopper”), which Zojirushi says was the industry’s first stopper with the gasket built in (based on its own 2020 survey). The Japanese page also says the lid has an air-insulation layer to limit condensation and that the 内面ラクリア加工+ interior is more corrosion-resistant than its previous electropolished finish, which is why it allows sports drinks.

The Japanese manual adds that repair parts are kept for 5 years after production ends and treats the lid set as a consumable to check about once a year.

Japanese names, dates, specs and prices from Zojirushi Japan (zojirushi.co.jp), its January 21, 2026 news release, the Japanese SD-KA manual and Zojirushi Direct, checked October 28, 2026. Prices include Japanese consumption tax.

Japanese reviewers on Zojirushi Direct, Rakuten and Yahoo! Shopping most often praise the lid: several say it opens with a light twist as easily as a push-button bottle, one buyer in her 50s with sore finger joints said it was easy to use, and parents buying for school-age children liked that it works one-handed. They also like the short parts list and the dishwasher-safe design, and one Zojirushi Direct reviewer said ice could still be heard inside the next morning. One parent said the 750 mL size was “just right” for a second grader. On the negative side, some buyers found it confusing at first that the lid unscrews in the opposite direction, one said the silicone bottom cover came off and was lost within 10 days and the bottom edge chipped when dropped, one worried the cap could open if a bag is thrown down, and one Rakuten buyer reported tea leaking from the sip area. Review counts are still modest because the line launched in 2026. (Third-party reviews, not our own testing.)

Zojirushi SD-KA60H vs SD-KA75H: Frequently Asked Questions

Should I get the Zojirushi SD-KA60H or SD-KA75H?

Get the SD-KA60H (20 oz) if you want the shorter, lighter bottle: 9-1/8 in tall and 11 oz empty. Get the SD-KA75H (25 oz) if you drink more during a workout or a long day out, or want the longest cold rating of the two: Zojirushi USA rates it up to 66 hours vs up to 47 hours for the 20 oz model. The 25 oz bottle is 1-5/8 in taller, about 1 oz heavier and $3 more at Zojirushi’s U.S. store ($46.99 vs $43.99). Width, lid, opening and colors are the same.

Can I put hot coffee or tea in the SD-KA Cool Bottle?

No. Zojirushi’s manual labels the SD-KA “Cold Only” and says never to fill it with hot beverages. If you need hot and cold, look at Zojirushi’s regular travel mugs instead, such as the SM-KHE or SM-VA series.

How long does the SD-KA keep drinks cold?

Zojirushi USA rates the SD-KA60H at up to 47 hours and the SD-KA75H at up to 66 hours. That is how long water starting at 40°F (4°C) takes to warm to 59°F (15°C) in a 68°F (20°C) room, so it is the time to “cool,” not “icy.” Zojirushi Japan gives a stricter figure: water starting at 4°C is 9°C (48°F) or lower after 6 hours in both sizes.

Is the Zojirushi SD-KA dishwasher safe?

Yes. Zojirushi says all parts, including the lid, body and bottom cover, are dishwasher safe. The manual adds limits: don’t use a commercial dishwasher or a separate dish dryer, keep the lid and bottom cover from falling onto the heating element, and don’t wash the lid with its cover closed. It recommends hand washing for longer life.

Can I put sports drinks, soda or juice in it?

Sports drinks: Zojirushi Japan says the interior finish is OK for them, and the English manual asks you to clean the bottle thoroughly after each use, especially after sports drinks. Carbonated drinks and dry ice: no. The manual also lists dairy, fruit juice, high-sodium liquids such as soup, and drinks with fruit pulp or tea leaves among things not to put in.

Is the Swiftwist lid leak-proof?

Zojirushi calls the lid leak-proof “when used properly according to the instruction manual.” The manual asks you to fill only to the fill line, close the lid fully and carry the bottle upright in a bag. It is designed for drinking directly from the bottle, and drinks may splash if you pour from it.

Do the 20 oz and 25 oz bottles share parts?

Yes. Zojirushi’s U.S. store sells one Lid Set for both sizes (S112, $19.40) and one Base Rubber bottom cover for both sizes (SP3, $13.25), in matching colors. The 34 oz and 41 oz bottles use different parts (S113 and SP4).

Why does my Zojirushi bottle rattle?

Zojirushi’s manual says the rattling sound is metallic foil inside the vacuum wall and is normal.

Check current listings

Amazon search results for Zojirushi cold bottles often mix the SD-KA with Zojirushi’s hot-and-cold travel mugs (SM-KHE, SM-VA, SM-SHE), the older SD-CS50 Cool Bottle, Japanese-market SD-KA60 or SD-KA75 listings without the “H,” and replacement lids or bottom covers sold on their own. Look for “SD-KA60H” or “SD-KA75H” in the listing before you buy.
