Micro Hydro

Hydro Flask's tiniest bottles, Japan-inspired

There's a certain kind of day that doesn't need a litre of water. The nip out to grab a coffee, the short commute, the quick errand run where hauling your full-size flask feels a bit like bringing a sleeping bag to a pub quiz. The Micro Hydro started life in Japan, where paring things back to just the essentials is less of a trend and more of a way of life – and it quickly became one of Hydro Flask's fastest-selling products. Now available in three sizes, there's a Micro Hydro for every occasion: the 200ml fits in the palm of your hand and slips into a coat pocket – the perfect vessel for an espresso shot, a thumb of whisky by the fire, or a glass of wine at camp. The 300ml is the sweet spot for workouts, errands and short commutes, small enough to drop into a crossbody bag without a second thought. The 400ml gives you a little more to go on – enough to tide you over for a few hours – without crossing into full-size territory. Don't let the dinky dimensions fool you, though. All three are proper Hydro Flasks under the hood: TempShield double-wall vacuum insulation keeps drinks cold for up to 20 hours and hot for up to 7, a leakproof screw cap, pro-grade stainless steel that won't carry over yesterday's flavours, and the brand's lifetime guarantee.
