What Stands Out
Ultralight Design
Weighing just over 1 pound, the Hyperion provides an exceptional warmth-to-weight ratio, making it ideal for backpackers seeking to minimize pack weight without sacrificing comfort or insulation.
High-Quality Down
Crafted with premium 850 fill power down, it delivers superior thermal efficiency and compressibility, ensuring both warmth and compact storage for easy transport on outdoor adventures.
Mummy Shape
The contoured mummy design enhances heat retention and minimizes weight, offering an efficient fit that optimizes warmth for cold-weather camping, keeping you snug and comfortable even in frigid conditions.
