Wonderful Pajamas

I’ve struggled for years to find a fashionable yet functional pair of pajamas, these are the best I’ve come across. My wife is also greatly appreciating the upgrade from the old t-shirts and sweat shorts!

Cool and comfortable night's sleep

I've really noticed a difference wearing Dagsmejan's Nattcool shorts to sleep in. I sleep far more comfortably during the warmer summer months. Would absolutely recommend and get more. Very happy with my purchase.

Cool, comfortable, and stylish!

I've long been in search of sleep shorts that would keep me cool during spring and summer nights. These do that better than any thing else I have found -- with the added benefits that they are super comfortable, look great, and even have useful pockets. Love them!

Coolest sleep ever!

Not sure why, but as I've gotten older I've found myself more and more frequently waking up in a small pool of sweat during spring and summer nights. I've tried several different brands of sleep shorts and tees in hope of solving this. Some were better than others, with Tommy John being pretty decent, but none truly eliminated the problem. But now I have discovered the Dagsmejan brand and their Nattcool sleep wear. It's not cheap, but it is worth every penny. VERY cool and comfortable, and stylish to boot. And don't be worried about their official policy that you should not put their stuff in the dryer -- I have done that dozens of times already without even a hint of any negative effect.
