The troop’s MSR WhisperLite stoves just keep going, even though the Scouts lose the windscreens. But we can buy replacements. Now, the stuff sacks are just worn out, but I e-mailed MSR and they are available as parts, though not listed on the website.
So, for $10 each, our stoves have brand new stuff sacks to keep the soot off the rest of our gear. They don’t say “WhisperLite” like the old ones, but they are pretty obviously MSR stove bags.
The next time I need a backpacking stove, I’ll think about who might have spare parts for me twenty years from now. MSR will be high on the list.
