Honestly the best pajamas ever.

I am a big believer in making sure you take care of yourself when it comes to sleep. Bed, sheets and pillows are all important, but so are pajamas. I've been wanting these for a while, and decided to splurge and by the nattcool set. This review is for both the shirt and shorts.

I was a bit skeptical, but when I wore them the first night I go them, I could feel the cooling sensation when I got a little warm. They do work, and they are awesome!!

As an added bonus, they are super comfortable and super stylish. I also love the fact that they are made in Europe and not China. You can tell they take pride in their manufacturing.

Dagsmejan will be the only brand of pajamas I ever buy!!

On another note....I live in Los Angeles, and DHL had them delivered to me in less than two days. Faster than it takes UPS to deliver something from the East Coast.

DO yourself a favor and get a set :)
