What is Symbium technology?
Symbium technology is all about optimising the structure of the waist belt and shoulder straps. This prevents the backpack from swinging around, which wears out the trekker.
How was this 70 L trekking bag made?
The Symbium trekking bag is built to withstand over time:
- Robust main fabric, also added to the side pockets and the most prone to wear.
- The assembly of the various parts of this bag has been tested to withstand high tension, particularly when it is filled, or to be manipulated repeatedly.
- Redesigned zip thickness to improve strength and robustness.
- Repairable bag: spare parts available.
What are the advantages of the wooden structure on this trekking backpack?
The construction of these wooden bars is stronger than traditional aluminium bars. They are resistant to moisture thanks to an external varnish.
Is this trekking bag repairable?
The MT900 Symbium bag is ultra-robust but will not last forever. That is why we have developed a range of spare parts to make it last for longer:
- Shoulder straps
- Waist belt
- Waist belt's foam pad
- Elastic bands
- Buckles
- Rain cover
