This is a recommended belly band for staying warm in the cold season. It's thin yet provides ample warmth, and its moderate thickness prevents bulkiness. It's easy to wear as an underlayer and won't interfere with your usual clothing. Made with smooth and soft wool (cashmere blend) material. It's not itchy and has an elegant feel, making it comfortable to wear for extended periods. Highly elastic with a gentle, non-constricting fit. Easy to use for both men and women, and useful for sleeping, working from home, and outdoor work. It snugly wraps around your abdomen, warming you from the core. Recommended for cold sensitivity and cold weather protection, as well as for protection against air conditioning. 【Sizes】M, L 【Color】Gray
