Małachowski Zion Ultralight donsjack - kobalt - maat S

Most lightweight down jackets sacrifice either warmth or packability, but the Małachowski Zion Ultralight delivers both in a 90-gram fill package. Built around premium 850 CUIN Polish goose down and a featherweight Pertex Quantum shell, it provides exceptional loft and heat retention for its minimal weight. Unlike bulkier insulated layers, this jacket compresses into its own zippered hand pocket, making it an ideal companion for mountaineering, trekking, and three-season layering where every gram counts.

Highlights

• Premium 850 CUIN Polish goose down: superior loft and warmth-to-weight ratio
• Ultralight Pertex Quantum outer and lining (29 g/m²) with DWR finish
• Stitch-through construction reduces weight and improves packability
• Packs into its own zippered hand pocket for easy storage
• YKK main zipper for reliable, snag-free operation
• Elasticated cuffs and adjustable hem seal in warmth
• Two zippered hand pockets keep essentials secure
• Unisex sizing in a striking cobalt colour

In daily use

Worn as a standalone layer on crisp autumn hikes or as a mid-layer under a shell in alpine conditions, the Zion Ultralight delivers consistent warmth without restricting movement. The lack of a hood reduces bulk when paired with a helmet or beanie, while the DWR-treated Pertex Quantum fabric sheds light rain and snow. The elasticated cuffs and drawcord hem allow quick adjustments to trap heat or vent excess warmth. When not in use, the jacket stuffs into its own pocket, taking up minimal space in a pack or climbing harness.
