ODLO BL Bottom Long Merino Trousers, Size L, Black

Cold-weather training and outdoor adventures demand a base layer that keeps you warm without weighing you down or trapping moisture. The ODLO BL Bottom Long Merino trousers answer that call with pure, mulesing-free virgin merino wool in a 200 gsm knit that naturally regulates temperature, wicks sweat, and resists odour. The slim fit hugs the body for efficient layering, while flatlock seams and a soft-touch finish eliminate chafing and itch. Whether you're skiing, hiking, or trekking in freezing conditions, these trousers provide the reliable next-to-skin comfort you need to stay outside longer.

Tips

For best results, wash these merino trousers on a gentle wool cycle with a mild detergent and lay flat to dry. Avoid fabric softeners, which can coat the fibres and reduce their natural wicking ability. Pair with the ODLO BL Top long-sleeve base layer for a complete merino system that keeps you warm and dry from first chair to last run.
