Nike All Conditions Gear is back, this time with a full trail running lineup

Nike is relaunching All Conditions Gear as a dedicated outdoor brand, and the first products are built for trail runners. ACG has been around since 1989, but spent the last decade leaning more into streetwear than actual trail performance. This relaunch is a reset. Nike Trail is being absorbed into ACG entirely, and the new lineup is designed for people actually logging miles on dirt.

What’s in the lineup

ACG Ultrafly is the flagship trail shoe: carbon-plated, ZoomX foam, and a Vibram outsole. The plate is split down the center so it flexes over uneven terrain, and the upper drains water quickly for wet courses.

ACG Zegama is built for longer efforts. Max cushion, wider toe box, and a rock plate for technical terrain.

On the apparel side, the Lava Loft Down Jacket weighs 10 ounces and packs into its own pocket. It uses 700-fill down with ventilation perforations placed where trail runners tend to overheat.

Radical AirFlow racing top is designed around maximum breathability during high-output efforts in heat.

All four products were developed with ACG’s All Conditions Racing Department—28 elite trail runners across eight countries who test prototypes and give feedback.

Trail running reaches a new scale

Trail running participation in the U.S. has grown more than 25% in a few years, but the category has mostly belonged to outdoor-first brands like Salomon and Hoka. ACG is Nike’s first serious attempt to compete here with purpose-built gear rather than adapted road shoes.

Where to shop

The Ultrafly and Lava Loft are available now at AllConditionsGear.com. The Zegama and Radical AirFlow top arrive in summer 2026.
