The Peter Storm Women\'s Merino Pants have a close fit and a stretch design making them the go-to pants for high-energy cold weather pursuits such as skiing and trail running.These pants are made from fine 17.5 micron wool that doesn\'t irritate the skin, stretches over the legs for optimum comfort, and pays special attention to your body temperatures at all times. When it\'s hot, the fibres of the Merino Wool will absorb your body\'s moisture vapours and evaporate them outside of the fabric - keeping you nice and cool so that you don\'t bake in the heat. On the contrary when it\'s cold, these moisture vapours will condense inside the fibre, giving off heat and keeping you nice and warm. This makes them a dependable pair of pants whatever the weather, whatever the activity.100% natural merino wool - Super-smooth against the skinTCS Warm Insulation - natural thermo-control for all winter activitiesSuperb moisture-wicking and quick-dryingIntegral merino anti-odour controlExcellent levels of stretchStretch designEasy button fastening
