Apidura Backcountry Full Frame Pack

The Backcountry Full Frame Pack is designed to fit a wide range of frame geometries, but because it fills the entire main triangle, it is best suited for bikes with standard frame shapes. We recommend checking Apidura’s online fit guide or measuring your bike's main triangle dimensions against the bag's specifications before purchasing.

Yes, the bag is designed with a versatile fit that accommodates bottle cages on the seat tube. However, depending on your frame size and bottle cage placement, you may need to use side-entry cages to make accessing your water bottles easier.

The bag is highly water-resistant and built to withstand rugged trail conditions, but it is not fully waterproof. If you are carrying electronics or items that must stay bone-dry, we recommend using a dry bag or waterproof stuff sack inside the main compartment.

The dual-zip system allows you to unzip just the top section of the bag for quick access to snacks or tools without opening the entire side. It is a convenient feature for grabbing essentials on the go without risking your other gear falling out.

Because it uses a secure hook-and-loop strap attachment system and features a reinforced structure, the bag stays very stable. When packed correctly with heavier items at the bottom, it maintains a low center of gravity that prevents the bag from swaying during technical maneuvers.
