Emdom 4x4 SUV fits a JetBoil well, I should know, I designed it, and I have a JetBoil =-) The Supply Captain/LBWolf/AITES Claymore pouch fits both the regular JetBoil PCS and the GCS pot in one pouch, the County Comm EOD bag is the same thing, slightly lesser quality, but cheaper. I've also stored both in an XL Kifaru PullOut. If a pouch is a tight fit on a Nalgene 1L wide mouth it probably won't fit the JetBoil.
