An industry-leading design for your best-ever climbs. Our Lumina 100 Down JKT weighs only 170g, with 70g of 1,000 cuin Italian down for next-level insulation and a ground-breaking warmth-to-weight ratio.

For mountaineers and technical alpinists, this versatile, lightweight layer compresses to the size of an apple, making it virtually unnoticeable in your pack. When it’s time to belay or take a break in sub-zero conditions, specialised down chambers maximise the jacket’s thermal performance for unrivaled warmth. The super-light, downproof, recycled Pertex® Quantum exterior uses a tightly woven construction to improve the insulation’s effectiveness and deliver high abrasion resistance – ideal for pushing your limits on unforgiving terrain. The provided repair kit makes it easy to prolong your jacket’s life after the toughest adventures. Our Lumina 100 Down JKT is one of the warmest, lightest choices for your future expeditions.
