Stanley Classic Legendary Bottle
Sturdy but heavy vacuum flask.
- Good heat retention
- Large cup with wide base (stable on uneven ground)
This vacuum flask (0.47 L / 16 oz) is rated to keep liquids hot or cold for 15 hours. I have not tested this: what I can say is that I have taken the flask on walks lasting six hours and it has kept my coffee hot throughout.
Stanley advertises its vacuum flasks as rugged and resistant to knocks. I have not tested this either (I like to take care of my gear). But I can believe it because the flask looks and feels hefty for its advertised volume.
I have tested the volume of the Stanley flask by putting the empty flask on an electronic scale, zeroing the readout, and filling the flask with water. I got a weight reading of 480 grams. Since water weighs one kilogram per litre (one of the advantages of the metric system), this weight equates to 0.48 litres—slightly more than advertised. By contrast, some other flasks overstate their volume.
The Stanley gets its burly appearance in part from its cup, which is bigger than average for vacuum flasks of this size. Three cupfuls will empty the flask. The cup has a wide, flat base, which gives it stability when set down on an uneven surface and makes it less likely to tip over.
The downside of this flask is its weight, which comes to 442 grams (15.6 oz) empty. Previously I owned Lifeventure and Thermos flasks of the same capacity and they weighed 362 and 358 grams respectively. The Stanley flask is significantly heavier.
So on the one hand the Stanley might be more durable than other flasks, but on the other it is not for hikers who want to keep the weight of their gear to the minimum.
I have had this flask for a year and other flasks for some years before that.
