【Product Description】 This windbreaker is designed for use in temperatures below 10°C and is suitable for a wide range of activities, including cycling, hiking, and running. It can be easily and compactly stored by turning the pocket on the waist inside out. (Size when stored: approx. 17cm x 13cm x 7cm, weight: approx. 120g) When you get hot during exercise, you can take off the windbreaker, fold it up compactly, and store it in a saddlebag, etc. As well as being a windbreak jacket, it is also water-repellent, so it can be used as a raincoat. Mesh material is used in the armpit area, and there is an opening in the back. This is designed to prevent sweat from accumulating inside the jacket and to release it to the outside. To prevent the sleeves from flapping during cycling, the fabric uses a material that stretches slightly horizontally. Size: M Gender: Men's Sleeve: Long Sleeve
