SYSTEM LAYER GUIDE

L3 - Active Insulation
Eco-friendly & Bulk-free Insulation, Self Stowing, Layerable or Standalone, Weather Resistant

Ultrapackable
Compresses down into a self-stowing pouch to ensure protection when and where you need it.

Sustainable Insulation
Biodegradable synthetic down made from 100% post-consumer recycled content keeps you warm even while wet.

Light & Tough
20-denier micro ripstop finished with DWR is well-prepared for standalone wear.
Adaptable Insulated Protection
The Ultra Lochi L3 Jacket features a fully reversible design that delivers two styles in one, with an adjustable hood and tough weather resistance available to both sides. Biodegradable insulation retains warmth without bulk and functions even while wet, and a self-stowing pocket ensures convenient, space-saving storage when not in use.
Purpose-Built Adaptability
The fully reversible design includes an adjustable hood that flips with the rest of the jacket and a pair of zippered hand pockets for each side (slightly staggered to avoid zipper stacking). A self-stowing hand pocket allows you to pack the Ultra Lochi down into itself for easy, compact storage until needed.



PrimaLoft® Bio™ is biodegradable* synthetic down crafted from 100% post-consumer recycled content, representing an important step toward drastically reducing the amount of micro plastics in our landfills and oceans. In accelerated test conditions, PrimaLoft® Bio™ fibers reach near complete biodegradation in under two years, while standard polyester remains almost completely intact.
Sustainable Insulation
PrimaLoft® Black Bio™ synthetic insulation retains heat without adding bulk or weight. Water-repelling fibers breath during active use, dry quickly, and continue to perform even while wet. The supersoft, lightweight construction compresses down and unpacks again without loss of loft.


Sustainable Production
The Ultra Lochi is crafted with bluesign®-certified textiles—verified for ecological safety at every step of manufacturing—and is certified STANDARD 100 by OEKO-TEX® as free from harmful levels of more than 100 substances.
Standalone DWR Protection
Both sides of the reversible jacket are finished with a durable water-repellent (DWR) coating, ensuring uncompromised versatility when worn as an outer layer. A center-zip wind flap teams up with a high collar and chin guard to help block out chilling breezes and stray precipitation, and a droptail hem provides extended coverage.
