Product Description

The Treeline Sleeping Bag is a budget down bag that is ideal for three season use when you’re confident the temperature won’t drop below freezing. While Sea to Summit 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. The two-way YKK #5 side zip with anti-snag fabric provides easy access and ventilation for warmer weather. Utilising our unique internal cord tunnel in the hood and neck draft tube, the Treeline’s exterior finish is kept neat and free of additional loose fabric. The internal chest pocket is a great spot for keeping valuables secure, or batteries warm. The 50D Nylon shell and lining fabrics provide long-term durability while still offering good compressibility. Light enough for backpacking adventures, this sleeping bag can withstand the rigours of sharing your outdoor adventures with kids or dogs.
