Purpose-Built for Trail Runners
Nike ACG expands its performance offering with the Lava Loft Down Jacket, created for athletes who move through variable terrain and shifting temperatures. Designed after extensive field testing in locations like the Dolomites and the Rio Grande, the jacket adapts to movement, rest, speed, and weather changes with ease.

Breathability Meets Insulation
The jacket’s performance comes from a precise combination of ExpeDRY™ Gold down and Nike AeroLoft venting. These elements work together to deliver warmth during slow moments and airflow during intense runs. Using detailed Atlas body mapping from the Nike Sport Research Lab, designers placed insulation and perforations exactly where trail runners need them most.

Engineered for Harsh Conditions
Its outer construction uses Nike Dri-FIT, Repel four-way stretch, Ultra UV protection, and DWR-treated recycled baffle materials. This mix helps the jacket stand up to sudden rain, wind, and temperature swings without sacrificing mobility.
Lightweight and Packable
Weighing only 10 ounces in a men’s medium, the jacket packs into its own pocket with ease. A reminder to respect the outdoors — “Pack it in. Pack it out.” — is stitched inside, capturing Nike ACG’s environmental ethos.

Backed by Athlete Testing
Lava Loft’s debut at the China International Import Expo highlighted Nike’s focus on pushing outdoor innovation. It sits alongside the ACG Ultrafly trail super shoe and Nike’s developing Radical AirFlow heat-control technology, both refined through extensive athlete testing. The recently formed All Conditions Racing Department continues this mission by putting every ACG design through high-speed, high-pressure real-world situations.

The Nike ACG Lava Loft Down Jacket will be available globally on January 1 at nike.com and select retail locations.
