Soft but flimsy
Color: Dark Navy, Size: One Size
Its soft and warmth is ok, but it feels very thin and a bit flimsy. The knit at the top looks particulary fragile. I think for the price this is still ok value but I do not expected it to last a long time.

Cashmere but far too thin
Color: Dark Navy, Size: One Size, Color: Dark Navy, Size: One Size
The beanie feels soft and genuinely made of cashmere, but the fabric is surprisingly thin — almost transparent when held to the light. It lacks the warmth and structure you’d normally expect from a cashmere item. The design and packaging are pleasant, but the overall impression is disappointing. It’s comfortable to touch yet too delicate to provide real protection against the cold.

Cool hat.
Color: Dark Navy, Size: One Size
This is a nice little hat. Even though it’s really thin, it does seem to keep my head warm. Really haven’t tried it out in the wind yet. But saying that you could put another hat on top of it.
