Men's Baselayers

When you're out in the cold, the baselayer makes or breaks your day. That's why we've pulled together the best men's baselayers selection, tried, tested, and loved by our Trekitt team in the hills, on the trail, and everywhere in between.

Whether you're gearing up for frosty morning runs or multi-day mountain missions, the right layer next to your skin is everything. We're big fans of men's merino wool baselayers. They are soft, breathable, naturally odour-resistant, and brilliant to wear—perfect for when you're working hard and still want to stay fresh.

You'll find top performers like Rab men's baselayers, built for serious mountain days, and Icebreaker baselayers, the masters of high-quality merino. and Devold merino wool baselayers, crafted in Norway and trusted for their softness, durability, and ability to perform in harsh Nordic conditions. And if you're after comfort with conscious creds, Patagonia men's baselayers bring technical design and more planet-friendly fabrics into one solid package.

From snug, stretchy men's baselayer tops to breathable options for high-output adventures, we've got layers to suit every mission.

Not sure what you need? We've got your back—just let us know, and we'll help you pick the perfect one for whatever the outdoors throws your way.
