Is the Balance baby sleepwear anti-bacterial/ anti-smell?

NATTWELL™ fabric has a patented technology which means that the fibres are both hydrophobic and hydrophilic, this helps to prevent buildup of bacteria which leads to odour in two ways. Firstly you experience less sweating in sleep as the fabric is extremely breathable allowing for excess heat to be released. Secondly, if you start to sweat this moisture wicking pajamas ensure that most of the moisture is transported to the outside of the fabric where it evaporates instead of being absorbed by the fabric itself.

The tests show that you keep your skin temperature 1 degree Celcius cooler with Dagsmejan and that the moisture on the skin is significantly lower.
