How hot/cool is inside out grid fleece? (R.5/Cap4)

I have a Patagonia R.5, like Capilene 4. Any opinions on the upper comfort range when worn inside out?

I’ve been carrying it in my everyday backpack to change into if I sweat, or layer if it’s cold. I’m curious if it will be obsolete in the summer. So far I’ve found it pretty comfortable while milling about or riding a bike, but it hasn’t gotten into the 80s or 90s much.
