"Warm clothing for active walkers" for those who keep walking even in the harsh winter

This is finetrack's signature active insulation wear, containing three sheets of Fine Polygon®, a sheet-shaped three-dimensional heat-retaining material.
This is a piece of clothing that will be most appreciated by those who spend a lot of time on the move during winter mountain hikes.

PolygonAct smoothly absorbs sweat, disperses it, and evaporates it throughout the garment, keeping the inside dry even in situations where you sweat a lot. Its greatest feature is that it prevents you from losing energy due to cold sweat while you're active, allowing you to keep walking while wearing it.

The outer fabric is made of lightweight stretch nylon, and the three-dimensional patterning provides a comfortable, lightweight feel that follows your movements. The lining is treated with an antibacterial and deodorizing agent, and Fine Polygon® itself does not retain moisture, so odors do not build up even during long periods of activity or multiple nights on mountain trips.

Winter mountaineering, backcountry approaches, cold weather running and trekking...
It is ideal for those who want to stay warm while moving and avoid sweat buildup.
