Miraculous! Cool on hot nights, warm on cool nights. Wonderfully comfortable, such that I am tempted to wear pyjamas all day, and not bother to put on clothes!
Soft. Breathable. Built for better sleep. The Men's Long Sleeve Merino Tee from Sleepy Merino is your new everyday essential — whether you're winding down for bed, lounging on the weekend, heading on a camping trip, or building your travel capsule wardrobe. Made in Australia from pure, superfine Merino wool, this insulating fabric feels luxuriously soft next to the skin (zero itch!) and naturally regulates your body temperature for all-season comfort and climate management.
Unlike clingy base layers, this tee is designed specifically for sleeping and layering. It helps wick heat and sweat away when you're warm, thanks to its moisture wicking and temperature regulation properties, then insulates to keep you cosy as the night cools. It's lightweight, breathable, and naturally odor-resistant — fighting odor-causing bacteria for freshness all day. You won't want to take it off.

Care Instructions
Use a normal warm to cool machine wash cycle with wool wash or a regular PH Neutral powdered or liquid detergent, just find one without whiteners, brighteners, stain removers or enzymes. Detergents which have 'Don't use on wool or silk' in the small print contain a nasty wool eating, skin irritating enzyme called protease. Separate lights and darks as usual.
Drying
Dry flat in shade to best preserve shape and colour. You can dry on the line, but expect some twisting of the garment and seams. As with any garment, inside out and out of excessive sun will help prolong the depth of colour.
We offer Domestic and International Delivery.

I have purchased Sleepy Merino t-shirts and sleep shorts over the past few years. Started off with one set bought on impulse at an Ag Show and these worked out so well I bought several more sets a year later. Even the oldest t-shirt I bought a few years ago is as good as new after many washings. My most recent purchase was a long sleeved t-shirt and I expect this will also be great. I am a very satisfied customer!
