Nice
Color: Black, Size: One Size
This cap is soft and doesn't pull my hair out. I fits comfortably under my construction hat

Soft and durable!
I bought this for my husband as a christmas gift and so far it’s been great quality! He works outside and I wanted to get something warm and soft for the winter. It’s been washed (and air dried) 3-4 times in the last couple of months and it’s held up great!! Such good quality for the price. He says it’s very soft and warm and prefers it over itchy wool.

Favorite. Hat. Ever.
I don't usually write reviews but I though I would this time for two reasons. Ordered one of these in black from Amazon and it showed up in a nice giftable box and the hat itself is really nice. Soft, warm cashmere. Favorite hat I've ever had. The fit is perfect. Not too large, not too small. Overall very impressive and a super reasonable value too!
Here is my warning: There were different colors available of course, one of which was a dark green which became unavailable. So I went to Villand's website where they had the dark green available for purchase for $26. I bought a second hat from Villand directly and it TOOK 18 DAYS for delivery! There is no phone number for customers to call on Villands website. I wrote twice asking about the order and heard nothing back. The tracking number provided did not work until about three days prior to delivery. I was honestly surprised when it showed up in the mail. I thought the money was gone and no hat was ever giong to arrive. No idea where it was shipped from but assuming over seas somewhere. My recommendation is to purchase via Amazon and NOT FROM Villand directly.

Best beanie!
This was a Christmas gift and the receiver loved it! It was just what he wanted! Cashmere is always the best choice for comfort, softness, wearability and durability!
