Soft but easily rolls down
Size: X-Large, Color: B004
Comfortable and soft but it kept sliding down, I have a longer torso so that could be why, but I couldn’t get it to stay up, it would constantly roll into my C-section scar

Warm and comfy thermal wear
Size: Small, Color: Navy
They are very soft, don't ride up. Clothes do not stick to them like other thermals do. The fit is perfect. They are warm and comfy. The quality is good, too.
