Clinically-backed infrared sleepwear for deeper sleep and overnight recovery.

Sleep deeper, wake fresher. The KYMIRA Men’s Infrared Recovery Sleepwear Bottoms use bio-responsive minerals to recycle body heat as far infrared (FIR), supporting circulation, tissue oxygenation, and thermoregulation throughout the night.

In KYMIRA’s research summary, wearing KYMIRA sleepwear during sleep was associated with a +15.9% improvement in sleep quality, a -15.8% reduction in fatigue, and a -13.6% reduction in soreness by morning.

Designed for comfort, breathability, and nightly use, these bottoms turn rest into active recovery for athletes, shift workers, and anyone seeking improved sleep quality and recovery.

Why Infrared Sleepwear?

Infrared sleepwear has been shown to support improved sleep quality, reduced fatigue, and reduced soreness overnight
KYMIRA fabric supports nitric oxide production, improving circulation and oxygen delivery linked to deeper sleep quality
Applied studies report a 15.9% improvement in sleep quality and a 13.6% reduction in soreness when worn during sleep

Deepen your recovery overnight with these Infrared Sleepwear Bottoms, designed in a jogger-style fit for comfort and ease of movement. The soft fabric gently contours to the body while maintaining breathability throughout the night.

A flat waistband helps prevent digging in around the waist and hips, ensuring uninterrupted comfort during sleep.
