Gals can wear this too!
Color: 2 Pack(black+white), Size: XX-Large
Do you know how difficult it is to find a cotton mock turtleneck??? This review is NOT for guys but for gals. Being in menopause my temps are all over the place-- one minute I'm hot then I'm freezing. I needed a short sleeve (plus size) cotton mock turtleneck to wear under a cardigan. I'm so pleased with this shirt... the fabric is soft, NOT see-through, it's breathable since its primarily cotton (95%), it's not super tight, and it's comfortable. Hopefully the info will help other gals looking for similar shirts.
