The D-12 UL is an ultralight down jacket built for the moments when the temperature drops but you still want to travel light.

It packs down small into the included stash bag, ready for cold mornings, windy ridgelines, and long days that stretch into chilly evenings.

Built with a Pertex Nano Shadow Ripstop outer, it combines low weight with added durability and a refined technical feel, while 700 fill power RDS-certified down delivers serious warmth without unnecessary bulk.

A cozy high collar seals in heat when the weather turns, a two-way zipper regulates comfort, and zippered hand, chest, and inner pockets keep essentials close.

Minimalist design and refined lines reflect The Mountain Studio´s commitment to Swiss alpine engineering and timeless style.

Built with a Pertex Nano Shadow ripstop shell, a PFAS-free DWR treatment, RDS-certified 700 fill power down, and YKK Vislon zippers, it is a year-round staple you will reach for again and again.

Available in Otter, the D-12 UL works as a standalone jacket in crisp conditions or a warm layer under a shell.

This ultralight down jacket is trusted for packable warmth from mountain hikes to colder days in town.
