Nike has just relaunched its outdoor-focused All Conditions Gear (ACG) line, and if the marketing activation is anything to go by, it's on track for big things.

The next chapter positions ACG as a dedicated outdoor-performance brand, backed up by some serious technical kit and star-studded line-up of athletes across trail-running, hiking and exploration. To mark the occasion, the Oregonian sportswear behemoth pulled out all the stops and created the All Conditions Express – a heritage Italian train, transformed into a rolling ACG basecamp, transporting adventurers between Milan and the mountains.

The train itself has been reworked to mirror ACG’s blend of utility and community. Seating compartments double as distribution points for gear kits tailored to changing conditions. A café carriage, styled after an alpine refuge, acts as the social heart. Elsewhere, a rolling laboratory hosts workshops and product deep dives.

Introduced in 1989, the original premise behind ACG was straightforward: make products that could handle a range of environments without requiring the wearer to be a specialist. You did not need to summit a mountain. You just needed to go outside.

In practice, ACG became a place where Nike experimented. Trail shoes with aggressive outsoles. Jackets that balanced weather protection with packability. Graphics that nodded to hiking culture. The line sat somewhere between performance equipment and lifestyle clothing, but over time, different designers have pushed the project in different directions. Some eras leaned technical. Others leaned aesthetic. This new age sees the brand leaning more serious performance and less lifestyle.
