Retention hours only compare when the stated conditions match · review
A 0.75 liter flask that publishes a cold figure and no hot one, and whose rubberized screw stopper is stated to hold carbonated drinks.
A 0.75 liter double-walled stainless flask with a rubberized screw stopper, stated to be 100% leak-proof including with carbonated drinks, and stated odor- and taste-neutral.
The title publishes 24 hours cold. Nothing in the title or the bullets publishes a hot figure. Under a name built on coffee, that is a conspicuous omission, and it is reported here as an omission rather than guessed at.
The 24 hours arrives with no conditions, like every other figure in this hub.
This is the closure the hub describes best. A rubberized screw stopper, stated to open easily without slipping, holding pressure from carbonated drinks. Nothing is said about spare gaskets, which is the standard silence here.
No steel grade. No mouth diameter. No base diameter, on a bottle argued to be slim enough for any bag. No empty weight, behind the word light.
If you want one bottle for hot and cold, note that only the cold half of the claim is published here.
Not on Amazon.com. At our check on October 21, 2026, the reference opened a German-language listing marked currently unavailable, so the buy button on this page has no American offer behind it.
If what you want is the carbonated-drinks claim, the BLOCKHÜTTE on this insulated flasks shelf states it too, names 18/08 steel, and sold for $31.89 on Amazon.com the same day. For a hot-and-cold bottle from the same parent brand, the Thermos was $27.99.

The listing does not say. It publishes 24 hours cold in the title and no hot figure anywhere, which is unusual for a flask carrying this name. This page reports the absence rather than filling it in from the brand.
The maker states the bottle is 100% leak-proof including with carbonated drinks, and makes the point twice. Three other flasks here make the same claim: the Arendo, the BLOCKHÜTTE and the Limes 8. What none of them publishes is a replacement gasket, and the gasket is the part that carbonation works on.
Not from Amazon.com. At our check on October 21, 2026, the reference opened a German-language listing marked currently unavailable. For a cold bottle that also states carbonated drinks, the BLOCKHÜTTE on this shelf sold for $31.89 on Amazon.com the same day, and names 18/08 steel.
No. Not published on the listing — stainless steel is named, with no grade. What the listing does publish instead is the lid type: Rubberized screw stopper — stated, described as easy to turn without slipping, and stated 100% leak-proof including with carbonated drinks.
7.8/ 10
A clean, honest cold bottle with the best-described stopper in the hub. It publishes one retention figure out of two, and the missing one is the one the name implies.
Cold drinks, including carbonated ones, in a slim 0.75 liter bottle where the closure is the deciding part.
Amazon reports what buyers took in the month before this page was last checked: at least 200.
The figure is a floor, rounded by Amazon, and read through Keepa — it says what buyers picked, not what a maker claims.
Specifications: the manufacturer sheet for camping and hiking gear and the matching Amazon product page. Prices and availability: Keepa. Every figure on this page names its source.
1 liter · 18/08 stainless · 13 h temperature stability stated, hot and cold not separated · bottle brush, jute bag and carabiner supplied
A 1 liter flask supplied with a natural-bristle brush and a carabiner, whose single retention figure of 13 hours is never split into hot and cold.
Best for: A liter bottle bought with its brush and its carry loop, where cleaning matters more than a comparable hours figure.
≈ $33
500 ml · vacuum insulated · SUS 201 outside and SUS 304 inside · 24 h cold and 12 h hot stated · brushed finish · top handle
The only flask here that names a different steel for the inside and the outside, alongside a stated vacuum, both retention figures and a brushed finish.
Best for: A day out where a named inner steel, a stated vacuum and a dishwasher-safe body matter more than the hours quoted.
8 oz · TriMax triple insulation, the only triple-wall claim here · food-grade stainless, grade not named · 24 h stated once, hot and cold not separated · removable 3 oz silicone cup · folding hidden handle · dishwasher safe, flask and cup
The only triple-wall claim on this shelf, on an eight-ounce flask with a removable three-ounce silicone cup in its base — and a single 24-hour figure that does not separate hot from cold.
Best for: A hip-pocket flask for spirits or a single coffee, where two can share from one cup
