I'm in need of a lightweight windshield for my Jetboil but I don't want to fork out for one of the MSR foil ones as its just a length of foil! I was thinking of chopping up one or two of those foil trays that Tescos flapjacks come in but does anyone have any other suggestions for a source of heavyweight ali foil? =o)
In reply to Mr. K: I saw a photo blog of a guy who used a section from a drinks can, cut at one side to expand to fit that he just slipped under the neoprene cover when not in use. Can't remember where it was though (prob on here somewhere) sorry.
For the Caldera Clones, I've used large foil roasting trays from 99p Store.
For a JetBoil windshield, a flapjack tray, or sidewall of a beer can, as suggested above, tucked under the neoprene sleeve. Ready-to-cook lumps of meat often come in very sturdy foil trays, too; probably the thickest recycled food containers I can think of.
Just don't block much more than a third of the vents...
