How does this differ from the standard Nano-Air?

The Ultralight version uses lighter 40g insulation compared to the standard 60g, making it thinner, more breathable, and better suited for high-intensity movement rather than static warmth.

No, it is a breathable soft shell with a DWR coating. It will shed light mist and snow but will soak through in sustained rain.

Can I wear this as my only jacket?

It works as an outer layer in dry, cool conditions while moving. If you stop or if the wind picks up, you will likely need to layer a hardshell or a warmer puffy over it.

What is the fit like?

It features a slim, technical fit designed to sit close to the body. This helps the insulation and moisture-wicking properties work efficiently while fitting easily under other layers.
