As Caudron, I'm a little disappointed that a one-liter Nalgene bottle does not fit gently in this excellent cup. You can still put the partially up the side of the cap, and earn about 50mm on 83mm it measures. It will have to do. As for the mug itself is a pleasure to use: a generous capacity of 450ml, it allows the heat to value of a "mug" standard on the fire without filling it to the brim. We can handle it easily on uneven ground. Its large handles to avoid burns, and stainless steel, smoother than aluminum and plastic can be cleaned with a wink and gives no taste to foods. This mug offers the best value for money on the space race, and his only potential weakness could come welded fixings folding handles, as it folded withstand today the worst outrages of the outdoor life. Those who insist on successful marriage with Nalgene Everyday will prefer the titanium 750ml Esbit. Please be aware that it is little more lightly because for two people, and that it is not the same budget. In a different genre, there are old military canteen very compact, but they are opaque, often of a poor quality, and do not necessarily will return to the external thread of modern bags back.
