Convenient staff sack included for carrying.
This active insulation is developed for continued wear as a base layer. It features nylon material made partially from recycled sources, with stretch nylon fabric placed in the sleeves, elbows, and sides for a wide range of motion. Combining materials based on the ergonomics of running, it offers minimal tension even when wearing a backpack. The front and back incorporate 'Ventrix', a ventilated, stretchable synthetic insulation that excels in breathability and flexibility. It has rectangular ventilation holes at the center back for increased airflow where you sweat the most, complemented by fine V-shaped slits at the bottom that automatically open during activity and close during breaks for optimal ventilation. This unisex model has a slightly tight fit.
