HADAL
Engineered sleepwear for deeper, cooler, more restorative sleep.
Body temperature rises. Sleep fragments. Recovery suffers. You wake tired.
Traditional sleepwear hasn't changed for decades. It was designed for comfort, not for performance.
The last sleepwear you'll need. And the first that actually works.
Ultrafine merino wool, finished with Thermocline, built to disappear while you sleep.



100% ultrafine merino wool at 185 GSM. No polyester, no elastane, no nylon.
A light knit weight chosen for sleep, not a heavy winter wool. Enough body to drape, light enough for warm sleepers.
A xylitol and far infrared finish that draws heat the moment you perspire.
No silicone softeners, no PFAS, no formaldehyde, no optical brighteners.
Traceable ultrafine fleece, processed without chlorine.
Merino releases heat when you run warm and holds it when you cool.

100% ultrafine merino. 185 GSM.
One fibre, one weight, chosen for sleep. Nothing synthetic against the skin.
