Clever little gadget
This thing is great! Just finished using it for a Colorado Trail thru-hike and was very pleased by its usefulness. It’s ultralight and would easily stash in my food bag when not in use. Its most impactful benefit was helping me save both weight and volume by repacking freeze dried/dehydrated meals into quart size ziplock freezer bags and protected/warmed them as they rehydrated. Highly recommend adding to your backpacking kit.
