The Eberlestock Zip -On Dry bag is the perfect addition to your main frame pack system.
This 67 liter dry bag is the perfect addition to your pack system. If you have plans to be hiking in wet areas you need this dry bag. It can be zipped into the middle of your J79 Sckycrane, or add a couple of bat-wings and this dry bag to your main frame and you have the perfect high volume water proof, and light weight pack system.
When you get to your camp just zip the dry bag out of the bat wings and zip them together for a light weight day pack and leave all the gear you don't need with you in the dry bag at camp.
