VENEX's black thermal items are perfect for combating the cold. - Brand: VENEX - Size: One size - Color: Black - Purpose: Cold protection, thermal insulation This poncho-style item covers the head and drapes over the neck and shoulders. It's made of a light, thin, smooth polyester fabric that feels good against the skin. The high elasticity means you don't have to worry about messing up your hairstyle or makeup when putting it on. You can wear it under your top like a "detachable collar" to give the appearance of a turtleneck, making it suitable for going out. Also, it's a "loose turtleneck" that doesn't constrict the neck, so you can wear it comfortably for long periods, such as when sleeping. ~Good skin feel and comfortable to wear. Recovery wear that supports high-quality rest~ ◎ Proprietary material "PHT" polyester fiber Proprietary technology that supports high-quality rest. The wear, which incorporates various minerals such as nano-platinum into the fibers, gently envelops the body. ◎ Stress-free comfort Non-compression design that doesn't constrict the body. To reduce discomfort against the skin when wearing, we use soft thread to finish the seams flat [flat sewing] and highly elastic [omnidirectional stretch material] that responds to various movements during relaxation. We also pay attention to the comfort of the wear, such as [stress-free cutting] that lays out the seams on the front body side to reduce discomfort during rest, such as the seams touching the skin. I bought this, but I always forget to wear it when I sleep, so I've only used it about twice.
