Our most lightweight technical 800+ fill responsibly sourced down ready for rugged use and won’t weigh you down.

The secret sauce: Pertex® Quantum with Diamond Fuse Technology, which protects the down with an exceptionally durable and abrasion resistant shell.

The Helium Down Hoodie uses an exclusive waterproof version of Pertex® Shield with Diamond Fuse fabric on hood and shoulders for added weather invincibility.


We started infusing this tech into our award-winning Helium Rain products for its ability to add abrasion-resistant durability to waterproof shells. When the benefits became clear, we began to think outside of the box: How else could we apply Diamond Fuse technology to strengthen more of your favorite outdoor gear?

The answer was simple. We took one of the most important, yet fragile types of outdoor apparel – down insulation – and decided to see what type of a difference Diamond Fuse could make.
