Sensational sleep make

It’s soft, cool and stays in place all night! Extremely effective in blocking out light - much appreciated as I suffer from migraines.

We sleep so much better!!!

My boyfriend and I have both been having major problems falling asleep lately. We stumbled across this site and just ordered two sleep masks. We never thought that a sleep mask would really help so much. We now fall asleep within a minute and even sleep through without waking up once. We are more refreshed than we have been in a long time. I am so thrilled that I have ordered one for my mother as well.

Thank you so much!!! :)

Product FAQ

What is NATTRECOVER™ fabric?

NATTRECOVER™ is a textile finish which ensures that the energy radiated by the body is reflected back in the form of far infrared rays (FIR). This additional energy can positively affect the body’s performance capacity and wellbeing.

How does NATTRECOVER™ work?

Our NATTRECOVER™ fabric consists of a carefully curated titanium-mineral matrix. These minerals have particular properties which reflect far infrared rays. Through its use as a print, the positive energy from our body is reflected back to the body.

What are the benefits of wearing Recovery sleepwear?

Wearing Recovery sleepwear can positively affect performance capacity, balance and concentration, as well as wellbeing and regeneration.

What is far infrared energy?

All living organisms permanently emit energy into their surroundings. Carefully chosen minerals printed on to textiles reflect this energy in the form of far infrared rays. Far infrared is a type of energy on the infrared spectrum that can benefit the human body with enhanced cell function and blood circulation, aiding the body’s natural regeneration processes which occur during our sleep.

Is NATTRECOVER™ certified?

The minerals complies with bluesign® standards, the world’s most stringent production standard with regards to the environment, health and safety requirements which guarantees the greatest possible exclusion of substances that could be harmful to humans or environment and promotes the economical use of resources in manufacturing. All our partners in the garment making process are following highest oeko-tex standards.

How wash-permanent is NATTRECOVER™?

The NATTRECOVER™ fabric is washable and does not wear out either as a result of domestic washing or through long wear.

How shall I wash and care for my Recovery sleepwear?

Recovery sleepwear is washable up to 40 degrees Celsius. Do not tumble dry. Do not bleach. Do not dry clean.

You can also find the care instructions printed on the inside of your garment.
