Backpack that is durable and lightweight with a carry system that is comfortable for long expedition-type treks lasting several weeks. Eco-Designed thanks to the use of mass-dyed fabrics
Passionate about backpacking, we have developed this robust 50 L bag (+10 L extra) for men setting off independently to the mountains for several days
Capacity
Extendible volume: 50 L + 10 L extra (3051.2 in3 + 610.2 in3) thanks to the adjustable height of the bag top.
The volume of each backpack is measured using a standardized method:
We fill the main compartment as well as each pocket with little balls.
The balls are then emptied into a graduated container in order to determine the equivalent volume in liters, with a margin of error of just a few %
Weight
5.3 lbs
The empty weight shown is that of our reference TREK 900 50+10 L sample. There may be slight variations
Dimensions
Height: 27.2″
Width: 16.9″
Depth: 13.8″
How to pack a backpack?
Put your bedding at the bottom.
Place heavy equipment near your back (tent, stove, food).
Pack your clothes around these items.
Your sleeping mat can be placed under the flap and the tent under the bag if there is no room inside.
Keep a waterproof jacket and fleece to hand.
In the pockets, place small items for the day (sunscreen, map, glasses…).
The water bag should be placed in the compartment that is usually placed the length of the back.
Why are our rain covers gray when some trekkers want them to be brightly colored?
The gray color used for the covers of our backpacking rucksacks is neutral because it consumes less dye.
The component is made of BITON: this process allows us to lower our CO2 impact and reduce consumption and water pollution in comparison to colored models. These small measures demonstrate the commitment of Forclaz to improve the environmental impact of its products.
SYMBIUM technology
In order to be comfortable, a backpack must also be well-balanced while you walk. Symbium technology consists of a jointed waistband that allows the backpack to adapt to the backpacker’s movements when walking.
Thanks to the symbium system you can say goodbye to the swinging effect that tire out trekkers.
10-year warranty
Our engineers have conducted tests simulating the aging of rucksacks.
These tests are conducted on the components, seams and finished product.
The results enable Forclaz to guarantee the tested bags for 10 years from the purchase date shown on the receipt
