Custom JetBoil Pot. It’s a Flash (I think) with three small cutouts at the base. This lets it work perfectly with just about any 3 legged stove. I’ve used it with an FMS 116, Kovea Spider, FMS remote, and others. See the pics (stoves not included).

Primus coffee press. Fits perfect and is way better – and lighter – than the JetBoil one. Don’t want to press you coffee? Easily removed and gives you one of the lightest lids available.

Original sleeve. This setup allows you to turn your stove waaaaay down and still get quick, efficient boils. Be careful not to turn it up, actually. My guess is it is easy to get too hot. Mod does not hinder regular JetBoil function so the small mods don’t take away from that system – just adds the option to use your UL stoves instead of the heavy JetBoil ones.
