The Apidura Expedition Frame Pack 3.8L is a waterproof frame bag built for riders who want dependable in-frame storage for daily riding, longer trips, and bikepacking. Mounted securely inside the main triangle, it helps centre carried weight for a more natural ride feel while making full use of valuable frame space.
The 3.8L version offers a more compact setup while still giving enough room for tools, layers, food, and ride essentials. Internal Zipper Control Rails help prevent bulging and keep the waterproof zipper running smoothly, even in rough conditions. Frame-fit panels conform more cleanly to the shape of the tubes, while Hypalon stability straps and silicone detailing help keep the bag locked in place over mixed terrain. A cable port allows for charging on the go, and the internal layout adds practical organisation with a main compartment, anti-rattle pocket, internal mesh pocket, and a gear attachment point for added versatility.

Sizing & compatibility
The 3.8L version is a more compact option in the Expedition Frame Pack range and suits riders who want practical frame storage with a slightly lower overall volume. Knee-clearance shaping helps reduce body contact, while the considered sizing approach is intended to give a more secure fit across a wide range of bikes.
Care & washing instructions
Hand wash only with mild soap and water. Air dry fully and avoid machine washing or tumble drying to help preserve the waterproof construction and overall shape.
