The Framus 58L is the perfect pack for multi-day adventures where long food carries and heavier pack loads require a rigid frame for superior weight transfer. The Framus is also their 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 Framus features some of the most technologically advanced waterproof materials to create a pack that is both very lightweight and durable.


  • Functional load lifters
  • Two contoured aluminium stays. Designed with a special curvature to form a 2-3 cm (about 1″) gap with your back for improved ventilation. Can be adapted to the form of your back and shoulders.
  • Optional (included) removable 9mm 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 9mm lumbar padding for extra comfort.
  • Comfortable 11mm (7/16”) thick shoulder straps, padded with EVA-foam and 3D spacer mesh. Selected use of 3D mesh around neck area for added comfort.
  • Side pockets, shoulders straps and hipbelt in 210D Robic HDPE fabric, for durability and flexibility.
  • Reinforced bottom section with Ultra400 fabric.
  • Comfortable 38mm (1.5″) wide webbing at the hipbelt.
  • V-style webbing straps for carrying extra gear over the roll top closure
  • Roll top closure with lateral attachment.
  • Ice axe attachment point at the base of the front mesh pocket, plus elastic clip for extra securing.
  • Functional 4-point compression cords that fully cover the pack sides from top to bottom, allowing to significantly reduce pack volume when needed and stabilize the load.
  • Taped seams (only when choosing Ultra200 and DCF as pack material). Seam tape is applied to increase water resistance and increase seam strenght. A pack liner is suggested to ensure pack content remains dry.
