What Packs Best in Your Waterproof Framebag?

Any down layers that need to be kept dry.

Your flat kit; extra tube, tire sealant, tire lever, pump, etc.

Water bladders fill framebag nooks better then hard plastic bottles.

Large food items that need to be kept dry.

Electronics that can’t get wet.

Tent poles inside against down tube. 

The roll-top designs lends itself perfectly to its fully waterproof construction, making it one of the most durable and adventure-ready framebags available.
