If you have a JetBoil, no need for Titanium cookware. Maybe I can add fleece in that spot. (I was in the Andes when fleece clothing first arrived. The Indian MOMS love it!)
I need to try the Miox. My days of enjoying the ritual of pumping water are looonnnggg gone.

Thanks for posting this. You’re right, fleece would have been a nice addtion. And cookware isn’t needed with the jetboil. And the funny thing is.. I don’t have a jetboil and i still use aluminum cookware. I’m so 90s… and so cheap… 😉
I have a few more– Dick Kelty’s waist belt– The pot grabber– Fold-up platypus bottles– The Sierra Zip Stove– Therma Rest mattress
