The NASA temp control really works—I stayed comfortable all day without overheating. Just note it runs small, so I’m glad I ordered up a size.

I wasn't sure if the temperature-regulating fabric would actually make a difference, but I wore it on a warm afternoon and stayed cool without feeling clammy. The jersey knit is soft and lightweight, though I did need to size up because it runs small.

The jersey knit is incredibly soft and really does keep me cool, but I had to exchange for a size up since it runs small. Once I got the right fit, it's become my go-to for lounging.
