Choose options
Endless possibilities
This ultra-technical backpack is packed with features and accessory options for all types of alpine sports (ice axe holder, pole holder, helmet holder, ski/snowboard holder, carabiner and quickdraw holders, etc.).
The thinnest breathable back protector certified to EN1621-2 Level 1, the Koroyd Propack can be integrated as an option; it slips into the pocket specially designed for it. It’s very flexible, so you can’t feel it, but it protects you in the event of a fall and from objects in the bag.
The front opening, inherited from paragliding, with its double slider, gives you easy access to the entire main compartment. The Mountain is made of resistant materials, tried and tested for over 10 years in all conditions on our paragliding products. NEO offers you a durable product, covered by a lifetime warranty.

The ventilation system is innovative in several ways:
- It allows ventilation of your back during effort, providing a cooling sensation when you wear a light layer of clothing on your skin.
- It is ergonomic because, unlike other ventilated frames, the NEO frame conforms to the shape of your lower back.
- The ventilation system does not encroach on the interior volume of the backpack.
- Ultra-light fiberglass frame.
- Ergonomic shoulder straps and waistband.
- Machine washable at 30° C.

Technologies

Fiberglass frame
The frame of the NEO Mountain backpack is made of fiberglass, which significantly reduces weight compared to traditional mountain backpacks available on the market.
The flexibility of fiberglass allows for the design of ergonomic shapes and has enabled the integration of the innovative ventilation system of this backpack.
Fiberglass also helps to enhance the comfort of the backpack while maintaining rigidity; lightness, rigidity and ergonomic shapes are essential for comfortable carrying.
Koroyd Propack protection
A pocket has been specially designed to accommodate the ultra-light Koroyd Propack and optimize its effectiveness. The Propack, which weighs just 150 g, is not felt, and the bag retains its comfort.
NEO protectors use Koroyd technology for ultra-light, innovative impact protection. The Koroyd tubes instantly and consistently deform on impact, absorbing maximum force in a controlled manner, minimizing the energy transferred to your back.
The Koroyd Propack back protector is available as an option.



Dyneema® Ripstop
Robust materials: Ripstop Dyneema®, high- tenacity polyamide, fiberglass, and aluminum buckles.
The technical collaboration between the Catalan textile manufacturer IBQ and NEO has made it possible to develop a Dyneema® fabric on a high tenacity Polyamide base, all coated with Polyurethane. This highly technical fabric combines the characteristics needed for outdoor products:
- Highly tear and abrasion resistant
- Minimal stretch
- No deformation
- Dirt-repellent and washable (30° max)
- Very light
- Best compromise between durability and lightness

RECCO® is a technology used by rescue teams as an additional tool for finding people buried by avalanches or lost in the wilderness more quickly.
