UPVOTED FLASKS
Some like it hot – especially when it’s coffee or soup and things are getting a bit autumnal out there – so Chris Rowlands picks the best heat-keepers
MEDIUM MUGS
The beefy brewer
Lifeventure TiV Wide Mouth (800ml)
With a handle and wide-mouth spout, this flask is short and stout. Tougher than any little teapot, it’s copper-coated to contain heat for up to 8hrs. A second cup inside the lid means you can make it a party for two, while the grabber on the side folds down flat for post-pour packability.

The winter warrior
Sigg Thermo Flask Gemstone IBT 0.75L
When it comes to bottling winter warmth, the Swiss do it with utilitarian flair. Packing for a trip to Hoth? With its sci-fi lines, the Gemstone’s full metal jacket is built different: an ultra-thin inner wall saves weight, while those sculpted grooves improve grip and enhance durability.
