Retention hours only compare when the stated conditions match · review
A 1 litre vacuum flask with a wide mouth stated to take ice, a screw lid with a vacuum seal, a carry handle and a non-slip silicone base — and no dimension behind any of it.
The bottom line The wide-mouth litre of the hub, with the best cleaning story and the same blank line as everyone else where the diameter should be.
A 1 litre black flask in stated 18/8 food-grade steel with double-wall vacuum insulation, a screw lid with a vacuum seal, a carry handle and a non-slip silicone base. All parts are stated dishwasher safe.
The hub splits on this. A narrow mouth pours cleanly and loses less heat; a wide mouth takes ice, takes a brush and takes soup. This listing states it is wide, states it takes ice cubes, and states cleaning leaves no unreachable corners.
What it will not do is give the figure. No listing in this hub does, so wide and narrow remain words rather than a comparison.
24 hours cold, 12 hours hot — stated, with no conditions behind them, exactly as everywhere else here.
No mouth diameter. No base diameter, despite a silicone base being a selling point. No empty weight, on a litre flask with a handle. No coating named behind sweat-resistant and several colours. No spare seal.
Wide-mouth flasks are harder to drink from while walking, and this one carries a litre. If you want one bottle for both drinking on the move and refilling with ice, that trade-off is the one to think about.

The listing does not give a figure. It states the mouth takes ice cubes without difficulty and that cleaning has no hard-to-reach corners, which is a description rather than a dimension. No flask in this hub publishes a mouth diameter.
The maker states all parts are dishwasher safe, which on a lid with a vacuum seal is a stronger claim than most listings here make. What it does not say is whether the seal should be taken out first, or where a replacement comes from.
