Technical Information

EASYFIT system
Our patented EASYFIT system lets you adjust the back height and strap tension simultaneously by pulling on one single strap (on each side). Put on your bag 2. Fasten and tighten the belt 3.Pull straps (from top to bottom) And you're done!
Dying process
Textile dyeing requires a lot of water but also produces waste water from the dye baths. To reduce the environmental impact, we have opted for mass pigmentation (also called Dope Dye), integrating the colour pigments from initial thread manufacture. This process reduces the CO2 emissions of this backpack by 35% compared to the old model.
Volume of 50 litres. The volume of each backpack is measured using a standard method: we use small balls to fill the main compartment as well as each pocket. The balls are then emptied into a graduated container in order to determine the equivalent volume in litres, with a margin of error of just a few %.
How to pack a backpack?
Put your bedding at the bottom. Put heavy gear (tent, camp stove, food) near your back. Pack your clothes around these items. A ground sheet or tent mat can be placed under the flap or the bag (add straps) if they cannot be fitted inside. Keep a rainproof jacket and fleece close at hand. In the pockets, place small items for the day (sunscreen, map, glasses...). The water bladder can be placed in the compartment provided down the back
Why are our rain covers grey when some trekkers want them to be brightly coloured?
The grey colour is neutral and therefore uses less dye. The component is made of BITON: this process allows us to lower our CO2 impact and reduce water consumption and pollution in comparison to coloured models. These small measures demonstrate the commitment of Forclaz to improve the environmental impact of its products.
