Sleep Better in Merino Wool. 
Nature's Miracle Fabric

Nature's Miracle Fabric

Every Merino wool fiber has a waxy coating called Lanolin, which helps wick moisture away from your body, and act as a safeguard against odor-causing bacteria. This is what allows our Merino to stay breathable and dry while smelling and feeling fresh, no matter what you put it through.

Softer Than Cotton

Softer Than Cotton

This wool isn’t like your typical itchy sweater. We only use superfine (15.5 micron) Merino wool, resulting in a luxuriously silky soft shirt that’s lighter and much softer than the average Merino or cotton shirt. It’ll also maintain its form over time and not get ruined after a wash, like most clothes these days.

Ultrafine Sleep Jersey

Ultrafine Sleep Jersey

Made from 15.5 micron ultrafine Merino wool, this sleep jersey is cloud-soft and temperature regulating—ideal for uninterrupted rest. Lightweight and breathable at 165gsm, it keeps you cool or warm as needed. Perfect for home or travel, it’s comfort you’ll look forward to every night.

    I love Unbound vlothes! These shirts are very comfortable. However, I don’t like that there are no pockets at all on these shorts. At least one pocket would’ve been nice.

    The best

    These are the most comfortable pajamas I've ever owned and they are perfect for travel. these shorts and an unbound tee shirt is all I bring for sleep. I highly recommend, and get a size up if you like the looser comfort compared to the perfect fit for regular life.
