Improving on perfection

Improving on perfection

We are extremely proud to introduce the Ultralight Down 2.0 Program. Representing the purest incarnation of our design philosophy, this is the remarkable result of a seven year product cycle, a continuous strive for improvement, and our collective expertise in down technology.

Outstanding insulation-to-weight ratio.

Redesigned for exceptional performance

The Ultralight Down 2.0 Program features new innovative materials, upgraded technical features, improved fit, and a substantially reduced footprint while remaining as incredibly versatile, lightweight and ultra-packable as its immensely popular predecessor.

Recycled and recyclable

The most important upgrade is the new Japanese technology 100% pre-consumer recycled 10-denier nylon ripstop. It is more lightweight while more durable, weighing a featherlight 28 g/m2.
Garments are filled with premium 850 fill power European goose down that is PFC-free, RDS-certified, bluesign®-certified, allergen-free, 100% recyclable and completely source track verifiable.

Even warmer

The Ultralight Down Hood 2.0 has a regular fit and can be worn as a standalone or insulation. It is as incredibly ultra-lightweight as its predecessor (328g / 11.6oz in size L) while effectively 15% warmer.


Outperforming the competition

These sophisticated ultralight down garments feature class-leading warmth-to-weight ratio and are built to provide packable warmth during fast-and-light missions in extremely cold conditions. They will outperform most premium specialist alternatives available on the market.


The Ultralight Down Jacket 2.0 is designed to be worn as an insulation jacket with an athletic fit. It is even more lightweight than the previous model (282g / 9.9oz in size L) while equally warm.

Extreme cold performance

Depending on individual circumstances, as a general guideline the Ultralight Down Hood 2.0 and the Ultralight Down Jacket 2.0 will keep you warm at -12°C / 14°F and -9°C / 16°F respectively when worn as a standalone over a base and a mid-layer during low-pulse activity.
