Finally decided to come up with a design for a stove bag.
Based on the standard "Tank" design that I make so no zips, just a couple of overwide flaps that fold over and are secured by straps with buckles.
1000d Cordura base and 500d flaps though happy to make from all 1000d if you'd prefer. The inside of the corners are reinforced with additional squares of cordura.
There is enough room to tuck in some heat shield material and a couple of bits of welding blanket.
Top straps are long enough to tuck additional gear underneath.
$40 Cdn for bags to fit 18" stoves, $50 for 24" stoves, plus shipping ($15 in Canada)
