I can only think of one “catastrophic” break in almost 60 years of backpacking. When I buy gear I try to balance cost, weight, and durability, with durability the first priority. I still use a lot of backpacking gear that is 30-50 years old.
A bigger problem, for me, is gear that I like becomes obsolete.
Back in the ’80s, on the first night of a week-long trip, my stove broke. It was an Optimus 732 “Mousetrap” stove. The stove used Hank Roberts style canisters and somehow, I broke the needle that is inserted into the canister. Optimus did replace it for free, but that didn’t help for this trip.




I needed a new stove, as I was in a wilderness area that didn’t allow campfires. I was able to hike to a small mountain town, which was two days away. This required a complete change in my route, to include my return point.
I was able to buy a Gaz Globetrotter stove in this little town. It became one of most favorite pieces of gear of all time. It included two small pots, a pot lifter and the stove is stored inside the pots. The pots also fit my 50 year old Svea 123. I soon bought a second Globe Trotter, foreseeing that it would probably be discontinued at some point in time. I did not foresee the canisters would also be discontinued, making the stove obsolete.


Roger will chime in that those canisters are dangerous. I never have had a problem. I still have a couple full canisters.
A while back, I was able to fit pieces of a Coleman stove into one of my Globetrotters and can now use standard canisters.

I documented the conversion in this article on my website:
