Brand: Stanley

The Stanley Quencher H2.0 FlowState has become THE reference for large-format insulated tumblers, made from 90% recycled stainless steel. Its vacuum double wall keeps drinks cold for up to 11 hours, or 48 hours with ice. The 3-position FlowState lid (straw, wide opening, closed) and ergonomic handle make it a daily companion, at the office or in the car thanks to its cup-holder-compatible base.

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.

The Stanley Adventure Outdoor Cooler carries over the brand's DNA, well known for its ultra-tough thermoses and water bottles, into a 15.1-litre passive cooler. Its double-wall foam insulation keeps ice for up to 36 hours, while its stainless steel shell and flat lid, sturdy enough to double as extra seating, make this a cooler built to outlast a single camping season.
