In detail: Stanley Quencher H2.0 FlowState Insulated Tumbler 1.2L
Over the past few years, the Stanley Quencher H2.0 FlowState has become the most recognisable insulated tumbler on the market, fuelled by massive social media hype. Beyond the phenomenon, it is built from 90% recycled, BPA-free stainless steel, with a vacuum double wall that keeps drinks cold for up to 11 hours, or 48 hours with added ice.
Its generous 1.2-litre size makes it a daily companion designed to cut down on refills, with a narrow base compatible with most car cup holders. The ergonomic handle with comfort-grip inserts makes it easier to carry, a detail that matters for a tumbler this size once filled.
The FlowState lid, the design's centrepiece, offers 3 positions: an opening with a built-in reusable straw, a wide opening for drinking directly or adding ice, and a fully closed setting for transport. The whole unit is dishwasher-safe for easier upkeep despite its size.
The Stanley Quencher H2.0 FlowState suits anyone looking for a large-format insulated tumbler for home, the office or the car, with genuinely effective all-day cold retention.

Our tester's verdict: Guillaume Hoarau
Hard to resist the curiosity around the Stanley Quencher phenomenon, and hands-on testing confirms much of the product's reputation. The 1.2-litre size is generous, ideal for cutting down on refill trips whether working from home or driving, thanks to a base that fits most car cup holders. The FlowState lid is the real strong point: the straw position is handy day to day, the wide opening makes adding ice easy, and the fully closed setting reassures for transport in a bag. Cold retention lives up to its claims, easily outlasting a full workday with a few ice cubes added in the morning. The empty weight of 650g is noticeable once filled, a genuine over-a-kilo tumbler to carry, and the price stays high compared to a standard insulated bottle. But the build quality, generous size and design that went viral on social media justify the hype for anyone after a large-format daily insulated tumbler.
