Too tight.
Size: Small-X-Large, Color: Black
I have an average sized woman’s head, maybe a tad smaller. I’m 5’2” and weigh 135… the hat quality was nice but too tight on my head. I was wanting something not real snug, kinda floppy.

Might seem pricey, totally worth it.
Size: One Size, Color: Classic Grey
Was a little more than I wanted to spend, but hey, it's cashmere. Super light but sturdy. Stiching seemed a little off and had a couple of funny points but I gave it a few wearings and they smoothed out just fine.
I was looking for a tight fitting beanie for my bald head, hat size 7 1/4, with a bunch of loose fitting at the top like one of the seven dwarves and this one is form fitting. Perfect for my bald brothers and sisters out there.
Compared to almost an exact beanie I have in Marino wool, this is lighter, softer,and warmer.
Excellent buy.

The hungry mini schnauzer
Size: One Size, Color: Black
I bought this hat for my husband, twice. He loved the hat, and the dog did too. My dog Lola, ate the hat twice. With these cold, snowy New England days and nights, this hat was so warm, soft and felt great on his head, it was perfect until Lola decided if anyone would have it, it would be her! Is there any way you could possibly replace this hat??
