Montbell thick merino wool belly band (waist warmer). I am a slender woman, and I found it a bit tight when I tried it on, so I am selling it. I have opened the package, but it is only a try-on and is unused. The original packaging from when I purchased it is also included. It is a unisex size, and I selected S, but those who don't like tight fits may find it a little constricting, even for women.
