Made from lightweight polycotton that feels soft against the skin, it slides easily inside your bag and adds roughly 2 to 3C of warmth, while forming a clean barrier against dirt and sweat that keeps your main bag fresher for longer. At just 260g it packs into the included stuff sack and takes up barely any room in a rucksack, and it doubles as a clean personal layer for hostels and travel or a light standalone cover in warm weather. Machine washable and quick drying. Finished in grey.\n\nKey Fe
