If you are packing in, the constant rubbing of the edges of metal can prematurely wear outpanniers, mantises, and gear ( as in the tent or sleeping bags. The roundness and lack of edge or fold up stoves help allieviate that. .
The Sims fold up stove I have came with a heavy duty canvas covering type bag Size wise it fit nicely into a canvas pannier. It heated a 12 x 15 wall tent great. The addition of dirt, plus when the ashes build up more , they get a longer burn.
