My Snow Peak 600 comes with a titanium lid that fits nice and tight to facilitate boiling. I checked through my various cloth canteen holders and found one that was big enough to accommodate the lid placed below the cup which in turn is nested around the Nalgene (or the recycled Gatorade bottle if I am really trying to save weight. A 1L platypus could also be used). I can also stuff in some HD aluminum foil for a windscreen. I found some very light weight plastic sheeting to place between the cup and the canteen - otherwise, the cup can become very grungy and I might not have a water to spare for cleaning.

Lids and windscreens have an enormous influence on the ability to boil water.
