Hikesity's no-screw bottles do something most insulated bottles don't: their product pages invite you to fill them with fizzy drinks. This guide skips the long physics lesson. It works through soda, sparkling water, kombucha and beer one at a time, then covers carrying, opening, cleaning and choosing a size, and it stays within what Hikesity actually promises.

The short answer: what makes an insulated bottle carbonation-safe
Most insulated bottles tell you to skip carbonated drinks. A sealed screw cap traps CO₂ pressure until the drink sprays or the cap forces itself off. Hikesity's no-screw cap takes the opposite approach. It has a built-in pressure-release (evacuation) valve that continuously vents excess CO₂ and equalises pressure the instant you open it.
Two features do two separate jobs:
- The valve stops the spray. Pressure doesn't build up behind the lid, so opening the bottle stays calm.
- The 316L medical-grade interior keeps the taste right. It resists the acidity of carbonated drinks without leaving a metallic taste.
For the full mechanism, read how the pressure-release valve handles soda and beer. For a side-by-side look at the two lid designs, see our comparison of sealed-cap and pressure-release bottles for carbonated drinks.
Drink by drink: what to expect

The product pages name four drinks as fair game: soda, sparkling water, kombucha and cold beer. Each stays cold for up to 36 hours thanks to double-wall vacuum insulation. The bottle holds a temperature rather than creating one, so start with a drink that is already cold.
Acidity links all four. Hikesity lines its bottles with 316L stainless steel, which contains 2–3% molybdenum. Standard 304 steel contains none. Hikesity rates the acid resistance of 316L as excellent and that of 304 as moderate. It also says 316L leaves zero metallic taste, while 304 can give one with acidic drinks. For background on the steel itself, our buyer's guide to 316L medical-grade stainless steel goes into detail.
Now the limits. The product pages promise two things: no spray when you open the bottle, and a drink that stays fizzy. They do not say how much carbonation remains after a given number of hours, so this guide doesn't either.
Soda
Soda is the drink that screw-cap bottles warn against most. With the valve venting excess CO₂, you can pour in a cold soda, close the lid and open it later without a spray. Soda is sugary as well as acidic, so plan to rinse the lid the same day.
Sparkling water
Sparkling water is the easiest of the four to live with. There's no sugar to leave residue behind. If you like a squeeze of lemon, Hikesity describes its 316L lining as lemon safe.
Kombucha
Kombucha is where the interior matters most, because it is both fizzy and acidic. The valve deals with the fizz, and the 316L lining, rated excellent for acid resistance, deals with the acidity. Your kombucha should taste like kombucha, not like the bottle.
Beer
The pages list cold beer by name, and the 36-hour cold rating makes the bottle practical for a picnic or an evening outdoors. Wash the lid when you get home so nothing lingers in it.
Carrying and opening it day to day

The routine Hikesity describes is simple. Fill the bottle, put it in your bag, and open it one-handed in about a second when you want a drink. There's no seized cap and no mess. The threadless lid opens, lets you drink and locks again in under 2 seconds, and Hikesity describes it as 100% leak-proof.
If your bottle goes everywhere with you, the Design Your Own 16oz bottle comes with a protective silicone boot. It helps prevent dents and keeps the bottle quiet when you set it down on a desk or table.
Cleaning after sugary or acidic drinks
Soda, kombucha and beer leave more residue than plain water, so a lid you can fully take apart matters. The threadless design pulls apart into 3 pieces in about 3 seconds. No threads or gaskets stay assembled, so there is nowhere for sticky residue to hide.
- Empty the bottle and pull the lid apart into its 3 pieces.
- Wash each piece and the inside of the bottle, paying attention to any spot where sugar could collect.
- Let everything dry before you put it back together.
The 316L interior also resists flavour transfer, so tomorrow's water won't taste like today's soda or kombucha.
Which size fits your drink
All three sizes share the same pressure-release valve, the same 316L interior and the same rating of 36 hours cold and 18 hours hot. The choice comes down to how much you drink and where you take it. You can see every option in the 316L stainless steel water bottle collection.
| Size | Best for | Options |
|---|---|---|
| 16oz (473 ml) | A single can-sized serving | Custom 'By You' edition (576 lid, body and boot combinations), Happy City, Walk City, Klein Blue |
| 20oz (592 ml) | Everyday carry | Top overall pick in the Hikesity Gear Lab 2026 buyer's guide; also in Klein Blue |
| 32oz (950 ml) | Sharing or a full day out | Gear Lab's pick for all-day hydration; also in Klein Blue |

16oz is about one serving, which suits a soda with lunch or a kombucha after the gym. The custom edition lets you mix lid, body and boot colours, and Klein Blue pairs a blue lid with a silver bottle. Happy City and Walk City round out the options.
20oz is the size Hikesity Gear Lab chose as its top overall pick, for its 316L steel, one-handed no-screw lid and zero metallic taste.

32oz is the one to fill with sparkling water for a long day, or to bring along when you plan to share. It's the same design, just bigger.
Frequently Asked Questions
Can I put soda in a stainless steel insulated bottle?
In a Hikesity no-screw bottle, yes. Its cap has a built-in pressure-release valve that vents excess CO₂, so soda won't spray when you open it. The 316L interior resists the drink's acidity.
Why do most insulated bottles say no carbonated drinks?
Most use a sealed screw cap, which traps CO₂ pressure until the drink sprays or the cap forces off. A pressure-release valve prevents that build-up.
Will my sparkling water stay fizzy in a Hikesity bottle?
Hikesity says carbonated drinks stay fizzy and never spray when you open the bottle. The product pages don't put a number on how much carbonation remains after many hours.
Is kombucha too acidic for a stainless steel bottle?
Hikesity lines its bottles with 316L steel, which contains 2–3% molybdenum. Hikesity rates its acid resistance as excellent, against moderate for 304 steel, and says it leaves zero metallic taste.
Can I carry beer in an insulated bottle?
Hikesity lists cold beer as fair game for its no-screw bottles. The vacuum insulation keeps it cold for up to 36 hours, and the valve keeps it from spraying.
How do I clean the lid after sugary drinks?
Pull the threadless lid apart into its 3 pieces, which takes about 3 seconds, and wash each one. With no threads or gaskets left assembled, residue has nowhere to hide.
Does the pressure-release valve make the bottle leak?
The valve's job is to vent excess CO₂. Hikesity describes the same threadless lid as 100% leak-proof.
