KILPI COMBO-M comes with a unique novelty in the form of seamless knitwear, which in combination with flat seams eliminates the formation of abrasions and offers freedom and freedom in sports performance. It has ventilation and ventilation zones, which, together with the quick-drying material, offer great breathable properties. The T-shirt has non-slip silicone prints at the end of the sleeves to prevent rolling up. The knit includes three practical back pockets and a small pocket for small items on the sleeve. It includes silicone prints on the shoulders that prevent slipping, for example, a running vest or backpack. Reflective zipper simplifies putting on and undressing. The material that was used in the production eliminates temperature differences during the day and at night. The T-shirt is therefore very suitable for extreme sports that mountains and especially trail running often bring.
