【Snow Mountain】I want to challenge the harsh cold! An "insulation" outer jacket that protects body temperature even when wet
In winter mountains, equipment is “life.” We found the perfect insulation outerwear for such harsh environments! It's lightweight, warm, easy to move in, and can be stored compactly. An essential piece for outdoor adventures in severe winter.
Cold-resistant outdoor wear
Winter mountaineering can leave you cold the moment you stop, stealing your body heat—finetrack's "Polygon Helios" is essential for such activities. It is strong against moisture and maintains stable thermal insulation even in extreme cold. Its ease of putting on and taking off is outstanding, making it a likely must-have item for winter outdoors!
Highly functional material you can rely on in cold regions
The secret to warmth lies in finetrack's unique insulation material, "Fine Polygon." The synthetic material, processed into a sheet-like form with a three-dimensional uneven structure, achieves a balance of lightness, warmth, and resistance to moisture. It incorporates six Fine Polygons in the body and four in the sleeves, effectively guarding against drops in body temperature even in sub-zero conditions.
Easy to move in and lightweight
Using a lightweight nylon fabric with stretch that doesn't feel bulky while providing warmth. Movements like bending, operating with your hands, and rotating your shoulders are smooth, making work and activities easy. The M size weighs approximately 450g, designed to be lightweight and comfortable for long wear without fatigue.
Additionally, its loose silhouette allows for easy on and off even over thick gloves and outerwear. Both the exterior and lining have been treated with water-repellent processing, so snow and water bounce right off.
Comfortable gear even in freezing temperatures.
The product features a Vislon zipper that is resistant to freezing even in subzero temperatures. It opens and closes smoothly, and the double-slider design ensures that there is no interference with harnesses or pockets. The wider cuffs make it easy to put on and take off even while wearing gloves, and the large hood wraps securely around the head with a drawcord to enhance wind resistance, effectively guarding against the cold around the face.
It also boasts excellent storage capacity, with one chest pocket on the outside and large inner pockets on both sides. Additionally, it can be compactly carried in its dedicated storage bag.
