When it comes to picking your trekking jacket, look out for fleece linings, hand-warmer pockets or cosy down and feather fillings. But, it’s not just staying warm you need to worry about when you’re hiking. It’s important to regulate your temperature and avoid overheating too, which is why all our seemingly thick trekking jackets are crafted from breathable, moisture-wicking materials and packed with ventilating zip and mesh panels.
