KEY FEATURES OF THE FRAMUS 58L PACK
• Two contoured aluminium stays. Designed with a special curvature to form a 2-3 cm (about 1″) gap with your back for improved ventilation.
• Optional (included) removable 9mm EVA-foam padding can be added to the internal back panel sleeve for comfort.
• 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 hip belt in 210D Robic HDPE fabric, for durability and flexibility.
• Reinforced bottom section with Ultra400 fabric.
• Comfortable 38mm (1.5″) wide webbing at the hip belt.
• 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 strength. A pack liner is suggested to ensure pack content remains dry.

REVIEWS
“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.”
"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." -
WHAT WE THINK
If you are an ultralight backpacker, there's a pretty good chance you own a frameless pack. These packs are often stripped of all the bells and whistles typically found on other branded rucksacks and come without a built-in frame. This, of course, is intended to shed weight and make the pack as light as possible.
Because of its 58L capacity, we’ve chosen the Framus to be our dedicated winter pack
We have tested the Bonfus Framus during the winter months in the Cairngorms, Snowdonia, and the Arctic Circle. It has endured connecting flights, scrambles in the pouring rain, rough winds, snow in the Highlands, and temperatures as low as -25°C in the Laplands. Overall, we are extremely happy with the pack, from the workmanship to its appearance. It feels just as appropriate in an airport as it does on the trail. -
