Our verdict · Researched

4.0 / 5

A genuinely well-insulated, tough stainless flask that will outlast a multi-hour hold-up on the hard shoulder. It's priced and sized more as an everyday lifestyle piece than a dedicated car item — at 9.4cm across the base it won't fit a standard car cup holder, so plan on a door pocket, footwell bag or boot instead.

Best for: Drivers who want a hot drink that's still properly hot after a long delay or a roadside wait, not just for the first hour
Skip it if: You only want a bare-minimum boot flask for emergencies

Researched, not used. We haven't used this product. This review is built from the maker's specifications, owner reports and our own sizing.

What we like

Manufacturer-rated to keep drinks hot for up to 24 hours, not just an hour or two
Durable 18/8 stainless steel, backed by a 1-year guarantee
Insulated outer lid doubles as a drinking cup — nothing extra to carry

Worth knowing

Heavy and bulky next to a dedicated travel mug
Wide base (9.4cm) won't fit a standard car cup holder

ⓘ As an Amazon Associate, PreparedBritain earns from qualifying purchases. We may earn a commission when you buy, or a fee when you request a quote, through our links. When two products are close, commission can decide which one we pick. A clearly better product always wins. Amazon prices come from Amazon's own product data and show the date and time they were retrieved. Prices at other retailers are checked by us, less often. Prices and stock can change at any time, so always check the retailer's price before you buy.

Who shouldn't buy this

Don't buy it if you only want a bare-minimum boot flask for emergencies — a £12–15 basic stainless flask keeps a drink hot overnight too, and this is priced for daily use as much as for the glovebox.
