Our Fabrics

Feathered Friends has always been at the forefront of fabric technology. We pioneered the use of GORE-TEX® in sleeping bags decades ago, and we continue this tradition to this day as we employ some of the newest and most innovative fabrics available. Down garments and sleeping bags require a soft and supple fabric to achieve maximum loft, and thus maximum thermal efficiency. There is a fine balancing act between fabrics that are just too fragile for use in an outdoor application and those that, while durable, negate the effectiveness of the down insulation. We have carefully chosen fabrics throughout our product line to complement the intended use.

We always strive to maintain the balance between durability and weight, and offer fabric choices for many of our products so you can choose what best meets your needs. For example. Some fabrics such as the Pertex® Endurance® at less than an ounce per square yard, tip that scale in favor of superior weight savings, where Schoeller® Nanosphere® fabrics weigh slightly more for enhanced durability.

Pertex® Shield® | Winter & Expedition Sleeping Bags

Pertex® Shield® technology combines water resistance with exceptional moisture vapor transport ability while the soft nature of the fabric allows the down to achieve maximum loft. The combination of weather protection, moisture management, and durability makes this a great shell fabric for our winter and expedition sleeping bags.

Pertex® Shield® | Expedition Garments

For our expedition line-up of down garments, we use Pertex® Shield® to achieve a superior degree of water resistance and moisture vapor transport. This is the burliest fabric we use. Highly durable, the larger yarns used in this fabric also allow for a greater degree of vapor transfer due to the larger spaces at the intersections in the weave. We employ this fabric for garments that face rugged use in challenging conditions.

Pertex® Endurance® | Ultralight Sleeping Bags

Feathered Friends pioneered the use of this ultralight water-resistant and breathable fabric in our UL950 line of sleeping bags which combine cutting edge fabric technology with the highest quality materials and 950+ fill power down. Refinements in fabric weaving and coating have made ever lighter fabrics possible, translating into many ounces removed from the weight of our ultralight bags. Besides the weight savings, this light and supple fabric also allows the super premium down to loft to the maximum. The difference in loft between otherwise identical bags made with Pertex® Endurance® and other leading waterproof/breathable fabrics is striking.

Pertex® Endurance® | Light & Midweight Garments

Pertex® Endurance® for our light and midweight garments is similar to the Endurance® series of fabrics used on our ultralight sleeping bags. This 20 denier fabric brings more durability, well suited for more exposure to abrasion and frequent wear. Incorporating the highest tenacity yarns available allows the fabric to maximize tear strength with minimal weight.

NanoSphere® | Daybreak Series & Three-season Sleeping Bags

NanoSphere® is a fabric treatment which, through the use of nanoparticles, alters the material to a much higher degree of water and stain resistance without blocking the natural porosity of the weave. It is a vastly improved version of the durable water repellant (DWR) treatment that most outdoor fabrics have. At a microscopic level, it gives water almost no surface to cling to causing it to bead up and roll off while also creating a natural self-cleaning effect. NanoSphere is oleophobic, which is beneficial to repelling a large range of potential contaminates such as body oils. The treatment is highly durable and more importantly, involves no potentially toxic or environmentally damaging emissions at any point of the manufacturing process. NanoSphere treatment can be rejuvenated with exposure to heat and we recommend drying your products at a moderate heat level to maximize this effect.
