Lightweight trekking jacket, only used a handful of times. Additional Greenland wax has been applied to the G-1000 sections of the jacket for improved weather resistance, but that can be washed out to improve breathability. Fjallraven description: Light, comfortable jacket for summer hiking in warm conditions. Made from G-1000 Lite with back and side panels in stretch fabric for good ventilation and freedom of movement. You can also open ventilation zippers in the sides to release excess heat on intense treks. Adjustable hood and hand pockets that are accessible even when you have a backpack on.
