ODLO Men's Merino 160 Long Sleeve Thermal Base Layer Top - Black - XL

Cold-weather training can be brutal when your base layer traps sweat and leaves you chilled. The ODLO Merino 160 Thermal Shirt solves this with pure mulesing-free merino wool that regulates temperature, wicks moisture, and resists odour naturally. Whether you're skiing, hiking, running, or just commuting on a frosty morning, this long-sleeve crew neck keeps you dry and comfortable without overheating.

Who is it for

Men who need a reliable, all-season base layer for high-output activities in cool to cold conditions. Ideal for skiers, hikers, trail runners, and anyone who values natural fibre performance. The slim fit makes it perfect for layering under midlayers or shells, while the soft merino fabric is gentle enough for everyday wear.

Tips

For best results, wash inside out with a wool-specific detergent and lay flat to dry. Avoid fabric softeners, which can coat merino fibres and reduce breathability. This base layer works brilliantly as a standalone top in mild weather or as a first layer under a fleece and shell in deep winter.
