Here's what other sites are saying:
Your all-synthetic baselayer looks like an antique next to the Stoic Men's Alpine Merino 150 Bottom. Alpine merino material gives you the breathability and warmth of merino wool combined with the durability and quick-drying performance of polypropylene--a powerful duo for conquering cold weather. Just pull this performance baselayer on before a long day at the ski resort or on the trail and you'll stay warm no matter what Ullr throws your way.
