When we launched the iconic Ultralight Down Program in 2015, it stood in a class of its own, without any real competition on the market, offering unparalleled performance and superior materials. Now, we introduce its successor: The new Ultralight Down Jacket 2.0 is equally warm as its predecessor, while even more lightweight, more durable and with upgraded technical features, improved fit, and a reduced footprint.
Designed to be worn under a shell, this full-featured down jacket features class-leading warmth-to-weight ratio and is built to keep you warm during fast-and-light missions in extremely cold conditions.
The Ultralight Down Jacket 2.0 is covered in a Japanese technology 100% pre-consumer recycled 10-denier nylon ripstop, weighing a featherlight 28 g/m2 and so thin that you might even see the actual down clusters through the fabric. The fabric is DWR-treated making it water-resistant and dirt repellent.
It is filled with premium 850 fill power 97/3-quality European goose down that is proprietary, plasma-treated, and water-repellent, maintaining its insulation capability even when wet. It is also PFC-free, RDS-certified, bluesign®-certified, allergen-free, 100% recyclable and completely source track verifiable.
Fit and technical details have also been updated using initiated inputs from our ambassadors and creative feedback from thousands of active users from all over the alpine world. It is now slightly longer with a straighter cut. The down-baffles have been redesigned for improved insulation. Pockets have been enlarged and adjusted. Hem adjustment is completely re-engineered, and we also incorporated the unique internal elastic cuffs we developed for the Guide Expedition Down Parka. Of course, it packs down into itself, using one of the pockets as a minimal stow bag.
Depending on individual circumstances, as a general guideline this jacket will keep you warm at -9°C / 16°F when worn as a standalone over a base and a mid-layer during low-pulse activity.
