These are available in both the 3 liter for compact pocket install and the 4 liter which work better in our Hydro packs!

Our MSR tanks are the most durable tank we have found and our fire crews beat these tanks up, they just keep on working great. These are 100 ounces and 130 ounces, that's a lot of H2o! They have a large fill port and it is positioned well with the supply hose, bite valve and shut off included. Just put it in your Nimrod packs pocket or in the HYDRO pack, that will attach to all Nimrod packs. The 3 liter tanks fits well in the N-150 packs interior pockets for a clean fit and the hose runs out a hose door so you can route it up and over your shoulder for easy access!
