What Stands Out
Ultralight Design
Weighing in at just over a pound, this sleeping bag offers unmatched portability for backpackers, ensuring you can travel light without sacrificing warmth or comfort during chilly nights.
High-Quality Insulation
Filled with premium 850+ loft down, this bag provides exceptional warmth-to-weight ratio, keeping you snug in temperatures as low as 5 degrees while maintaining breathability and compressibility.
Long Length
The long version accommodates taller individuals, enhancing comfort by allowing more room to move while ensuring efficient heat retention, making it ideal for tall adventurers seeking restful sleep outdoors.
