Framus 58L

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 our 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.

“I was really surprised about the comfort of the Framus backpack. Even pushing it way out of its designed carry load, I found it as comfortable as frameless packs with a standard 5kg base weight.” Matthias Ekman after his solo traverse of the Great Himalayan Trail. Read the interview here.

“[…] there is a secret sauce that I can’t quite identify that makes it (the Framus, Ed.) stand out. It was immediately apparent to me the moment I put the pack on loaded up — high-quality construction at a near best-in-class weight with an excellent carry. It’s hard to imagine anyone being disappointed in this pack.” Scott Nechemias. Read the review here.

• 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.
