When it comes to tackling wild terrain, few brands have mastered the balance of performance and personality quite like Nike ACG. Now, the outdoor offshoot of the swoosh is back with a new crown jewel — the 10-ounce, 700-fill Lava Loft Down Jacket, a featherweight powerhouse designed for athletes who thrive where the path gets rough and the weather unpredictable.
Inspired by the extremes of the Dolomites and the harsh swings of the Rio Grande, the Lava Loft isn’t your typical puffer. It’s built to adapt — to you, to the trail, and to the ever-shifting moods of Mother Nature. Nike ACG has poured four decades of mountain-tested madness into this design, creating what could well be its most refined piece of adventure engineering yet.
The Science of Staying Warm — and Cool
At its core lies a dual innovation: ExpeDRY™ Gold sustainably sourced ultralight down insulation paired with Nike AeroLoft venting. This clever mix keeps heat where you need it and releases moisture where you don’t, striking the holy grail balance of breathability and warmth.
The tech behind it isn’t guesswork. Using the Atlas body mapping system from the Nike Sport Research Lab, designers pinpointed the exact zones that trail runners need most protection and ventilation. The result? Precision-perforated panels ranging from hairline slits to two-centimetre vents — all fine-tuned over hundreds of hours of prototype testing.
The outer shell means business, too: a fortress of Nike Dri-FIT Repel four-way stretch, Ultra UV, and DWR hydrophobic recycled materials, crafted to take on mud, rain, and alpine chill in stride.
Light Enough to Forget, Strong Enough to Trust

Weighing just 10 ounces in a men’s medium and able to pack into its own pocket, the Lava Loft slips neatly into the “must-have” category for serious runners and mountaineers alike. Inside that pocket, a stitched reminder — “Pack it in. Pack it out.” — speaks to Nike ACG’s deep respect for wilderness stewardship and sustainability.
Unveiled at the China International Import Expo in Shanghai, the Lava Loft carries the brand’s 40-year legacy of outdoor innovation into the next frontier.
Built for the Relentless
Nike ACG isn’t stopping at jackets. The same relentless drive fuels the ACG Ultrafly, a trail-tuned super shoe tested over 13 rounds and 30,000 miles, and Nike Radical AirFlow, a next-generation material built to tackle rising global temperatures on race day.
There’s also the All Conditions Racing Department, a new squad of elite athletes who live to test limits — and every stitch of gear that bears the ACG badge.
The Verdict
The Nike ACG Lava Loft Down Jacket isn’t just another outer layer; it’s a statement piece for those who believe comfort shouldn’t cost performance. Ultralight, packable, and scientifically dialled to perfection, it’s the kind of gear that turns surviving the elements into an art form.
Available globally from January 1 at nike.com and select retailers, the Lava Loft is proof that Nike ACG still reigns supreme when the road gets rugged and the weather turns foul — because when you’re running wild, compromise isn’t an option.
