Its a med. which is one sz. Fits all. Which is a little snug. Recommend if you buy a cap it's best to get the slap cap adjustable so you can adjust like you like it.

The interior is already unraveling in less than a week.

I think my head is too small or something, the hat will not stay on.

Great! Especially for days you want an effortless look that's stylish.

Hello, I've been natural for 6 or 7 years now. We ALL know how important it is to make sure natural hair (any hair) is protected when laying down for bed. I would use bonnets, scarfs, caps, plastic bag etc... but having these items on my head (all night) caused me to have migraine headaches.... not to mention the forehead line from the impressions that most of my head caps would make overnight! I switch to sleeping on satin pillows. Sleeping on satin pillows caused me to have major breakouts. The products on my hair would get on the pillow cases and by me sleeping on the pillow cases, my face would come in contact with the products that would rubbed off my hair during the night. I order two of these caps. One for me and one for my daughter. I can't tell you how nice it is to sleep with something so light on my head! No lines on my forehead, no facial breakouts from products and most important, no headaches in the mornings! I'm going to give my daughter hers as one of her Christmas gifts, but I'm in love with the one I have and I can not believe I waited so long to purchase it! My hair is retaining moisture and it feels soft and fluffy when I remove the cap in the morning. I'm sure my 25 year old daughter is going to love wearing this to bed because, I honestly can't see myself going to bed with anything different on my head. I can't wait to clean out my bin of head caps... this is the best night gear for my hair! Thank you so very much for making such a strong, detailed and well needed product with all hair types in mind. I'm truly in love with it!
