It’s thin but really warm!
Color: Light Grey Melange, Size: One Size
This beanie is so soft and warm! It’s thin but feels as warm as my merino wool beanies from this company! They make great products! Who doesn’t love cashmere!

Compact & soft cap
Color: Dark Navy, Size: One Size
Great fall/winter hat if you’re looking for something that’s not too bulky. I wanted for a winter hat that I could just keep in my inside pocket of my winter jacket - problem was the pocket was not very big. I had another knit cap that just did not fit in there. The Danish Endurance beanie fits the bill! Being so thin, it is not my warmest beanie – but gets the job done! It also feels so soft. I bought another in a different color! The hat arrived with a few creases in it. You could steam it, but don’t really notice any wrinkles when you put it on. I wish they made it in a darker gray/charcoal.
