Merino is breathable and quick drying. It wicks moisture away from the skin and releases it into the atmosphere.
Merino wool can absorb up to 30% of its weight in moisture without feeling damp, making it ideal for managing sweat during sleep. This moisture-wicking ability helps keep kids dry and prevents discomfort caused by sweating, ensuring a more restful sleep.
Synthetics like polyester are not breathable. They trap hot air in and a sweaty, clammy child is at risk of overheating.
Cotton pajamas do not dry as fast as merino and get cold when wet, where merino does not.
