I purchased this item in January 2023 and have only worn it two or three times. It's an incredibly warm and lightweight product, but it's so warm that I haven't had many opportunities to wear it, so I'm putting it up for sale. From my experience, I'd recommend this to people who really feel the cold... I tend to run warm, so it wasn't quite right for me (sweat). This style is no longer in production, so it's a must-see for anyone who wanted it. I'm open to a small price reduction. Thank you.
