My wife bought this at a Montbell store, and after seeing her try it on again at home, it didn't seem to suit her, so she put it away without wearing it. Therefore, it is listed as new and unused. The product tag has been removed. Please refer to the tag on the inside of the hat for details. It is 100% polyester. Would it be suitable for spring to early summer? By the way, the chin strap was sold separately, so please purchase it separately. Please consider purchasing if you are satisfied with the description. I will not respond to comments asking for a price reduction, so please be aware of that. If you would like to see more photos, please feel free to ask. I will fold the hat up to ship it, so there may be some creases. Please understand. Also, returns are not accepted after purchase.
