The AirExchange fabric actually dries fast — I rinsed it in the sink at camp and it was good to go by morning. UPF 40 gave me peace of mind on a full day of sun, and it's light enough that I forgot I had it on.

Wore this on a dusty hike and the UPF 40 gave me one less thing to worry about. Only gripe is the cut runs a bit boxy through the waist, but the fabric stays light and breathable even in direct sun.

Wore this on a long, exposed ridge hike and the UPF 40 coverage kept my shoulders from frying. The AirExchange fabric really does dry fast after a sweaty climb, though the fit runs a bit boxy through the waist.
