Not only for sports endurance, but also for maximum comfort when hiking, it’s important to have a bottom layer that you can rely on. That's why we created the Merino Bjorn Pants design by wrapping fine fibres of merino wool around a durable synthetic core and creating a nylon-core. This innovative design is made from a material that combines the breathability, warmth, and antibacterial properties of merino wool with the durability and flexibility of nylon and elastane. The merino Bjorn Pants won’t give off a foul stench, even after you wear it several times. They’ll also retain their shape and won’t get punctured, even when they’re in for a really rough ride.
