The natural crimp in wool provides durability and elasticity, while hydrophilic properties wick moisture and thermoregulate the body to naturally cool or insulate you relative to ambient outdoor temperature. Moisture Management Merino won’t sweat it The ultra-fine merino fibers we use in our apparel are naturally breathable, which helps prevent you from feeling clammy, damp, or sweat-soaked when you’re exercising. While synthetic fabrics can wick away sweat, merino keeps the body cool during exercise by trapping that moisture and releasing it as vapor before it even condenses on your body. Natural Deodorization Minus the unpleasant odor Even if you wear your merino layers for a whole week on a grueling trek, you’ll be able to drink a celebratory pint at the end of the trail without bringing a cloud into the pub. Lightweight merino is an ideal layer for seasoned travelers, commuters who don’t want to change after their rides into work, and anyone hitting the road with limited luggage space or no time for laundry. Unbelievable Softness Incredibly Comfortable What is Merino wool better at than traditional wool? It’s super-fine and soft. A single Merino wool fiber is ⅓ the diameter of a human hair. It’s so fine, actually, that when it brushes up against skin, it bends out of the way. It can’t be prickly like other wool fibers because it can’t stand up to the weight of itself. So it’s soft. Really soft. Natural Sun Protection Ever Seen a Sunburned Sheep Merino fabrics are naturally resistant to UV rays without the need for chemical treatments. Our chunkier mid- and heavyweights offer UPF 50+, while our lightweight range offers around UPF 25. That means that while your muscles might feel the burn as you push for the summit, your skin most certainly won’t. 100% Climate Positive Wool Sourced Merino wool is Natural&Sustainable Because our Merino Wool grows perennially on our sheep's backs–no different than the hair on your head–Merino Wool is widely considered the world’s most sustainable fiber. Our premium Merino Wool fleece is shorn once a year by skilled shearers. The sheep’s wool grows back over the course of the following 12 months, producing a new batch of fiber destined for Climate Positive clothing material.

Regulates Body Temperature:From the slopes to the chalet, the natural fibres of Merino wool are excellent when it comes to regulating your body temperature. The breathable material retains warmth, but not to the point of overheating - providing optimal comfort in any condition.

Ofter Than Cotton:This wool isn’t like your typical itchy sweater. We only use superfine (17.5 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.

A Better Shirt Starts with Merino Wool:We bring the time-tested benefits of merino wool to everyday clothing. Wool allows us to make garments that you can wear more and wash less.
