Packrafts offer unmatched portability due to their inflatable design and lightweight materials, allowing them to be carried in backpacks for multi-day expeditions involving both hiking and paddling. Kayaks, on the other hand, provide greater stability, speed, and storage capacity, especially rigid models designed for various water conditions. For whitewater or long-distance touring, kayaks might be preferable, but for flexibility and ease of transport, packrafts excel.
