Retro-X. R1. The Houdini. Patagonia’s archive is full of iconic jackets for use on and off the mountain. But when it comes to modern technical performance, the Nano-Air ranks damn near the peak.
In Gear Patrol‘s original review back in 2014, we asserted, “The Nano-Air represents the future of protective outwear: a mixed bag of breathability, temperature regulation and comfort.”
It was a technical breakthrough in its debut, giving rise to a new category of versatile midlayers for high-output activities, and it continues to set the bar for active insulation more than a decade later.
Turns out, it also doubles as a killer urban jacket.

Like some of its Patagonia siblings, such as the Nano Puff and Synchilla Snap-T, the Nano-Air has long straddled the divide between mountainwear and urban aesthetics. However, a new entry into Patagonia’s catalog puts the pioneering technology squarely into the latter category.
