I bought whilst in the States this summer. V good it is too.

I can spell lantern. Honest.

Does it just replace the lid on a standard Nalgene bottle and you can still use it to carry liquids? (sorry to ask the bleedin obvious!)

Looks excellent!

I just put a piece of white expanded polythene over a headtorch to act as a diffuser. Weighs nothing, packs to nothing...

But a piece of polythene's not an exciting new toy, is it? ;-)

Depends on your boredom threshold, I suppose...

It says that it's waterproof, so I assume it replaces the existing lid.

I confess to liking the idea from a lateral thinking PoV.

What you really want is one with UV LEDs so that you can fit it on your Nalgene pee bottle, and have your pee fluoresce...

I want one with a goldfish.

It can (and does on mine) replace the lid. So it's dual purpose as well.

You can stand the bottle either way up too.

Oh, and it's got a dimmer facility too. Just right for those subdued lighting moments.

Dim the Firefly, put some Barry White on the mp3 player, then remember you've been wearing the same clothes for a week and left your toothbrush at home to save weight...

Nice!
