With the Framus, Bonfus sought to create a backpack that is lightweight enough for long and fast adventures and can provide a greater lever of comfort compared to traditional frameless packs. Bonfus achieved this by applying their no-nonsense, minimalist and practical design approach, using the most durable and lightweight fabrics & components that they could find, and taking advantage of the experience and craftsmanship of their skilled sewers.

It is Bonfus' most versatile pack: the frame and back foam pad can be removed when needed to transform the Framus into a frameless pack for fast and light trips requiring the lowest possible weight. The two contoured aluminum stays are designed with a special curvature to form a 2-3 cm (about 1″) gap with your back for improved ventilation and can be adapted to the form of your back and shoulders. 

The Framus features some of the most technologically advanced waterproof materials to create a pack that is both very lightweight and durable. Seam tape is applied to increase water resistance and increase seam strength. (A pack liner is still recommended to ensure pack content remains dry.)

The Framus 48L is the perfect pack for multi-day adventures where long food carries and heavier pack loads require a rigid frame for superior weight transfer.

*Note: Bonfus is switching the fabric for the pack body from Ultra200 to Ultra 200X and the fabric for the side pockets, shoulder straps and hipbelt wings from Robic HDPE to UltraGrid Black.


  • Internal Frame + Padded Hip Belt 
  • Functional load lifters

  • Optional (included) removable 5mm EVA-foam padding can be added to the internal back panel sleeve for comfort. If the pack is stuffed properly, the foam pad is not necessarily needed, to keep the weight down
  • Both the aluminium stays and foam padding are placed in an internal openable sleeve on the back panel, and can be removed to transform the Framus into a frameless pack and shed even more weight
  • Additional 5mm lumbar padding for extra comfort
