All About This Product

Why Choose the 3N1 System Bags?

Ultimate Temperature Versatility

The 3N1 System Bags offer three bag configurations, ensuring you stay comfy in any weather. Whether it’s cold or warm, you can switch between different settings.

Comfortable and Durable

Made from ultralight and durable materials, the Lost Ranger UL uses 850 fill DownTek water-repellent down. This ensures you don't have to sacrifice comfort for compressibility.

Certified RDS Down

100% certified Responsible Down Standard (RDS) down guarantees ethical and humane down sourcing.

Layering the inner and outer bags with offset quilting minimizes cold spots, ensuring maximum warmth. The inner bag, designed like our award-winning Sidewinder sleeping bag, is perfect for side sleepers.
