Material Tech: The fabric revolution in adventure backpacks
Backpacks are subjected to enormous physical stress throughout their lifespan. When designing new equipment, we ensure that the choice of materials is perfectly suited to its intended use. Exploring the possibilities of each fabric is not only exciting work: it ensures that each backpack performs as promised, even in the most extreme conditions.
There are many ways to measure the properties of a textile, but below we'll focus on the key factors that most influence performance.
WEIGHT
The weight of the fabric is one of the first aspects we evaluate. It's measured in grams per square meter (g/m²) or ounces per square yard (oz/yd²).
A lighter material can make a big difference in the user experience, especially in technical applications such as trekking, climbing, or trail running.
*Note on “Denier”: The term denier (D) is commonly used to refer to the thickness of the yarn used in the fabric (e.g., 1000D or 420D). However, a higher number doesn’t always mean greater strength: fiber type, weave, and finish can have a greater impact on final performance than denier.
A tightly woven 400D can outlast a coarser 600D.
ABRASION RESISTANCE
Abrasion resistance measures how much friction a fabric can withstand before deteriorating. It is assessed through controlled friction tests that determine the number of cycles before failure.
We always seek an optimal balance between weight and durability: lightweight materials with outstanding wear performance.
ELONGATION
Elongation indicates how far the tissue can stretch before breaking.
In most cases, we prefer materials with low stretch to maintain the backpack's shape and stability. However, in side pockets or stretch panels, a high level of controlled stretch can be beneficial.
TEAR RESISTANCE
This parameter measures the force required for the tissue to break or propagate a tear.
Ripstop fabrics—with reinforced grid-like threads—stop tears before they spread, which is essential for mountaineering or expedition backpacks.
WATER RESISTANCE
Waterproofing is tested under water pressure and exposure time.
Most technical fabrics include a polyurethane (PU) lamination or polyester coating , which prevents water penetration without compromising flexibility. Premium backpacks use TPU or ECOPAK™ film membranes, which are more durable and PVC-free.
OUR FAVORITE FABRICS AND NEW TRENDS
X-PAC®
Developed by Dimension-Polyant , this multi-layer laminate combines nylon , polyester and a cross-shaped X-PLY™ layer that offers structural rigidity, abrasion resistance and high impermeability.
Lightweight, technical, and highly durable, it has become the standard in ultralight backpacks and adventure cycling.
CORDURA®
A legendary brand in the outdoor world. More than just a material, it's a quality certification awarded by Invista , guaranteeing high abrasion resistance, durability, and softness to the touch.
Ideal for heavy-duty, urban, or military backpacks. Its technical canvas look offers a rugged, natural aesthetic.
DYNEEMA®, SPECTRA® and UHMWPE
Ultra-high molecular weight polyethylene (UHMWPE) is one of the world's strongest fibers, with a strength-to-weight ratio greater than steel.
Dyneema® or Spectra® fabrics are integrated into the structure, creating backpacks that are extremely lightweight, tear-resistant, and highly durable against UV rays and moisture.
More and more mountain brands are incorporating it into minimalist or technical mountaineering backpacks.
ECOPAK™ (Next-Gen X-PAC)
The sustainable evolution of X-Pac®. Made with 100% recycled rPET polyester, free of polyurethanes and PVC, and with a PFAS-free waterproof lamination.
It offers the same features as its predecessor, but with an 80% smaller environmental footprint . It's the new favorite among brands committed to sustainability.
GRAPHENE-INFUSED FABRIC
One of the most revolutionary innovations. The incorporation of graphene into the fabric reinforces mechanical resistance, improves thermal conductivity, and offers natural antibacterial properties.
Although still in the expansion phase, it is already being applied to high-end technical backpacks.
RECYCLED NYLON AND BIO-NYLON
Recycled nylons (like ECONYL® ) are made from fishing nets and industrial waste. They maintain the same performance as virgin nylon, but drastically reduce their environmental impact.
Bio-nylon (bio-based, derived from vegetable oils) is another emerging trend, combining lightness, elasticity and sustainability.
VINYL COATED POLYESTER / TARPAULIN
Also known as truck tarp , it is an extremely strong and flexible material, ideal for high-wear areas or structural reinforcements.
Its glossy finish and firm feel make it perfect for flaps, bases, or bottoms of urban backpacks. However, its heavy weight limits its use in lightweight backpacks.
In summary
Textile technology is transforming backpack design. It's no longer just about strength or weight, but about balancing performance, aesthetics, and sustainability .
New materials— from recycled ECOPAK™ to Graphene and Dyneema® —open a new era in outdoor manufacturing, where innovation meets respect for the planet.
