Thank you very much for viewing. This is the men's [Ventrix Shirt] from THE NORTH FACE. An insulation shirt that keeps the interior of the garment at a comfortable temperature regardless of changes in weather or activity level. It uses Ventrix, which has excellent breathability and stretch, with slits in the batting. By placing slits in areas that stretch a lot during mountain climbing, the slits open during exercise to promote ventilation, and close during periods of inactivity to increase heat retention. Laser holes are placed on the lining of the slits to promote exhaust within the garment. The fabric uses highly breathable, lightweight stretch nylon that smoothly follows the body's movements. It is water-repellent, so it repels light rain. Grid fleece is placed on the back of the shirt, where heat tends to build up during exercise. It quickly exhausts moisture while also providing excellent heat retention during periods of inactivity. It uses an electrostatic care design to suppress the generation of static electricity. This is a single piece that allows you to comfortably move around while wearing it during autumn-winter mountain climbing and outdoor activities. ◇ Grid fleece is placed on the back lining. I purchased it on Rakuten Ichiba for about 16,000 yen, but it didn't suit me, so I only tried it on and have been storing it at home. It's perfect for this time of year, so I'll give it to someone who will wear it.
