The MonkeyPack FE2/Pak is designed to safely stow your 2.6” diameter HG 100R Halguard™ fire extinguisher. And the integrated PR harness holds the included MonkeyPack. And when we say “hold”, we mean secure, rattle-free stowage that is ready for the toughest of trails. Unclip the buckle, and take the MonkeyPack wherever you need it. The included trail straps attach to your MOLLE seat back panel (JL Rubicon), or metal seat rail for extra hold on bumpy, or washboard trails.
