I've really become attached to my RC-4 and my SnowPeak Titanium cups. Two nearly indestructible necessities in the woods. Good thread.
1- I've got a SP Ti mug that I've also become very attached to- I found a lid for mine so it's near perfect now, also holds my stove, esbit fuel, windscreen, spork, mini bic w/ room leftover for a little soup/beverage
2- my Landi PSK
