Our Treeline™ Sleeping Bag is a budget down bag that is ideal for three season use when you’re confident the temperature won’t drop far below freezing. While we’ve given this design a little extra room around the shoulders and hips for freedom of movement, the relaxed mummy shape still provides efficient warmth and heat retention when you need it. Filled with 400g of compressible and lofty 600+ down, the Treeline™ will keep you warm and comfortable.
