The material is very soft and feels cool to touch. Rayon generally feels cool to touch initially but quickly gets warm with body heat, so I was skeptical, but this undershirt held up fine in the sun on a warm day in May when I had to walk a few blocks with a dress shirt and blazer on. I have previously only worn 100% cotton undershirts and this one feels at least as comfortable and cool.

I like the fit. I bought both S and XS and the latter fits me better even though my chest size for a dress shirt is 38 because Im skinny. The spandex allows it stretch just enough to be comfortable without feeling like a cheap rubberband.

I haven't washed it yet but going by otherscomments, Im expecting and hopeful it will hold up well.

There are no chafing tags and the seams are near imperceptible. The tone color is near-invisible under a shirt and the silky no-crease texture makes it superior to cotton on that front.

I wouldnt wear it outside by itself like a tee although on a hot day on a vacation, it wouldnt look weird. But more importantly, I would happily walk around wearing it before putting on a shirt at home with my girlfriend around because it fits so well. I wouldnt feel comfortable doing that with my cotton undershirts because they are hardly flattering. Wearing underwear that feels good even if no one can see it is priceless.
