All the Helium bags in the range use a Helium 20D outer fabric. Helium fabrics are our range of high performance woven downproof fabrics. Lightweight and ultra-compressible, Helium fabrics are the perfect choice for any product where weight and bulk are a prime concern. Their densely woven structure and use of fine denier yarns ensures these fabrics are down-proof, tear-resistant and highly breathable.
Downproof by construction, they do not use membranes and as such have unimpeded breathability. A nanoscale durable water repellence provides water resistance. Helium fabrics are constantly evolving as our fabric partners develop superior technologies. Weaving is a constantly changing field and in recent years the speed of developments has only increased. Before we commit to any new fabric, however, it undergoes extensive laboratory and field testing. Only the best survive.
