If you only plan to buy one bottle, we think it should be this one.
However, if what you have just described does not concern you, to choose, we prefer the sports cap of the Hydro Flask to that of the Klean Kanteen. It did not leak, even through the tiny valve which allows air to flow one way from the top (however, it is not sold for a plug completely free from leaks, because precisely from the presence of this valve). While water did escape from the valve of its competitor, the gourd Klean Kanteen, in two separate tests. The Hydro Flask valve is sealed with an inner cap when it is closed, making it easier to see that it is actually closed. The sports cap of its competitor running water bottle does not stick when closed, it is difficult to distinguish if it is hermetically sealed.
Like the other double-walled water bottles we tested, and unlike those with a single wall, the Hydro Flask does not “sweat” during normal use. The insulation works two-way: the cold water inside will not cause condensation on the outside.
If you choose to drink from the bottle, the Hydro Flask has a metal rim that mimics glass better than all the others, including the round rim of the Klean Kanteen and the thick, somewhat industrial neck of the Yeti Rambler. Its standard neck measures 4.4 cm in diameter, which is wide enough for ice cubes, but not enough to spray water if you drink it on the move.
This gourd is coated with a light, textured powder coating that keeps it from getting too hot if left in the sun. It exists in four sizes: 35, 53, 62 and 71 cl. The ideal capacity for us is 62 cl: it is enough not to have to fill it too often, but not too bulky either. The 71 cl format is large and slender, therefore potentially easier to overturn, and gives the impression of being bulky.
All types of water bottles are leaking. Whether they wear out, break or simply fall on a “weak link”, it is a reality with these products and all the models that we recommend in this buying guide have been accused of leaking or to have a defective plug at one time or another.
However, the reproaches made against Hydro Flask are rare and few. No bottle of the brand, whatever its type of stopper, leaked or showed itself to be defective during our tests. Unlike aluminum containers, they are not easily dented. Unlike those made of glass, they do not present any problem of cracking the base. And unlike plastic ones, they do not deteriorate quickly with use.
The Takeya Actives 71 cl has a silicone bumper sleeve to prevent bumps against hard surfaces. For the Hydro Flask, it must be purchased separately.
If we are looking for the little beast, it will be noted that this bottle and its lids must be washed by hand. The heat of a dishwasher can damage the insulated bottles and discolor their coating.
