LOVED THESE SO MUCH. FIRST, BOUGHT THEM IN A MEDIUM (I AM 5'3 AND 143 LBS -- WEIGHT GAIN OF 10 LBS DUE TO COVID 19), BUT THEY DID CURL UP. IT DIDN'T MATTER...I COULDN'T EVEN 'FEEL' ANYTHING DIFFERENT FROM THE MOMENT I PUT THEM ON -- THEY FLEX RIGHT WITH YOU -- SO SOFT. LOVED THEM SO MUCH, I BOUGHT THEM IN A LARGE. I WILL EITHER WEAR THEM TO BED...OR UNDER MY DRESSES. BOTH SIZES FEEL SO COMFORTABLE -- DOESN'T MATTER WHICH SIZE. IF THEY DON'T HAVE YOUR DESIRED SIZE, TRY THE NEXT SIZE -- YOU WON'T FEEL ANY PINCHING OR DISCOMFORT. AGAIN...SOOO SOFT.

Very soft and lightweight

Color: White, Size: X-Large

I bought this when I had shingles and needed something soft but thin as a barrier between my skin and a sweater or sweatshirt. This was perfect. It’s super soft, non irritating, and was lightweight.
