One of the softest things I own
Size: One Size, Color: Black
This Cashmere hat is the softest hat I have ever worn. It is not thick, and it is super stretchy, so fit really is one size fits most. It is incredibly warm. I love natural fibers, as they feel so much better on your skin, and they just work better (I live in a cold climate). This hat has a tiny bottle of nylon/elastsne to make it hold up better and fit better, but it's mostly Cashmere (94%). The wash instructions are simple: hand wash in cold water, roll in a towel, amd block/reshape. Amazon always likes me to comment on value for price on these reviews, and to be honest $98 (the price it was selling for when I ordered it) is rather steep. That is the only reason I didn't give that 5th star. I feel like this hat will last for a decade or more (if one of my kids doesn't steal it), so looking at it that way, the price seems more reasonable, but it is still a lot for a hat. Otherwise, I am absolutely in love with it. It's a little luxury in my winter wardrobe.

Delightful cashmere beanie
Size: One Size, Color: Heather Charcoal, Size: One Size, Color: Heather Charcoal
I love this beanie—I have been living in it since it arrived. The yarn is thicker than most of my other cashmere hats (I have several), and very soft. It is a little big on a smaller adult head (I roll it up, which also looks cute), so this hat should fit a wide range of heads. At time of review, this cashmere beanie from Everlane was listed at ninety-eight dollars. That's on the high side when compared to similar brands like Quince, but this is a well made hat and good quality cashmere. It would make an impressive gift.

Soft, Warm, and Perfect for Winter Weather
Size: One Size, Color: Black, Size: One Size, Color: Black
This beanie is incredibly soft and feels luxurious the moment you put it on. The cashmere has that smooth, cozy texture that makes it comfortable to wear all day without any itchiness. It provides just the right amount of warmth, keeping my head and ears protected during the cold winter months where I live. The ribbed design gives it a clean, classic look that works with just about any outfit, whether I’m running errands or heading out for a walk in the cold. It feels lightweight but still insulating, which makes it easy to wear without feeling bulky. Overall, it’s a simple, high-quality piece that delivers on both comfort and warmth.

Soft, warm, and comfortable
Size: One Size, Color: Black, Size: One Size, Color: Black
So so soft, this beanie is great. The knitting is this hat is great and well made. It has gotten cold and this keeps my head and ears nice and warm. A super comfortable, can wear all day without worry of it squeezing or causing pressure points. The value is great, cashmere is usually expensive. This beanie may be inexpensive but it is not cheaply made.

Super soft and plush beanie
Size: One Size, Color: Black, Size: One Size, Color: Black
This is a soft, plush, warm and comfortable knit beanie. I generally wear my hair in box braids and having a beanie that is both stretchy enough to fit without becoming too stretched out is important. This beanie does that perfectly. It also is soft enough that it doesn't make my hair feel dry or look super frizzy.
