Uniqlo AIRism

The value benchmark the whole market is measured against.

The verdict

At roughly a third of the premium price, AIRism gets you most of the way there on comfort and beats nearly everything on breathability. Seams and elastic are the compromise — expect a shorter life.

What works

+Unmatched cooling in heat and humidity
+Extremely low per-pair cost

What doesn't

−Seams fail earlier than premium pairs
−Thin fabric shows wear
