About the Big Agnes Lost Ranger 3N1 15

What is the Big Agnes Lost Ranger 3N1 15 good for?

The Big Agnes Lost Ranger 3N1 15 Down Sleeping Bag is perfect for camping in cold conditions. It provides exceptional warmth and adaptability for three- to four-season use, allowing campers to enjoy outdoor adventures while staying comfortable even in low temperatures.

How will some of the key features of the Big Agnes Lost Ranger 3N1 15 enhance my experience?

This sleeping bag features a mummy design with 650-fill DownTek™ insulation for warmth and water resistance. It includes an outer sleeping bag and an inner liner that can be used together or separately for temperature control. A two-way side zipper enhances ventilation, while the 3D hood and pillow pocket add comfort. The bag can also be secured to a sleeping mat, preventing shifting during the night. Made with bluesign®-approved and GRS-certified recycled materials, it is both high-performing and eco-friendly.

Why choose the Big Agnes Lost Ranger 3N1 15?

The Lost Ranger 3N1 15 stands out for its modular design, allowing campers to customise their warmth by using the inner and outer bags separately or together. Its DownTek™ insulation provides superior warmth and water resistance, ensuring comfort in varying conditions. Additionally, its sustainable materials and PFC/PFAS-free treatment make it an environmentally responsible choice.
