I purchased this for work, as I needed to enter an area where entry was prohibited. However, I never ended up using it, and it's been sitting unused. I'm selling it now as I have no further use for it. Sizes available are S and M. It's a women's item. This is a gray climbing helmet with ventilation. - Brand: mont-bell - Color: Gray - Design: Helmet with ventilation - Intended Use: For mountaineering and climbing - Straps: Adjustable straps Thank you for looking.
