The Xtreme base layer line from Thermowave is the second warmest design in their line. This makes the Merino Xtreme pants for men a good choice as base-layer for winter sports like skiing, snowboarding or running, hiking and biking.
These pants utilise a two-layered design where the outer is made of 80% wool and 20% polyamide, with an inner liner of 100% polyester. This gives the Xtreme optimum breathability whilst keeping you warm during long ski-sessions. Also, this is what makes these pants so soft and comfortable to wear.
