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.

Therm-a-Rest Sleeping Bags Editorial Review

The Therm-a-Rest Hyperion Sleeping Bag has received mixed reviews from customers. One customer was impressed with its performance, mentioning how comfortable and warm it was during low temperatures and how it provided a good night's rest for hiking the next day. They highlighted the quality and comfort of the sleeping bag, stating it was worth the investment for the level of comfort it provided. However, another customer had a different experience, sharing that the sleeping bag did not perform well in cold temperatures and left them feeling cold and uncomfortable. They mentioned instances where the bag was damp and not warm enough despite being within its comfort range. The customer expressed disappointment in the product's performance during more challenging camping conditions. Another reviewer praised Therm-a-Rest as a company and commended the ultralight design and build quality of the sleeping bag. They noted its exceptional packability and features but mentioned that the narrow cut of the bag could be restrictive for side sleepers, especially for those who toss and turn at night. From various customer experiences, it is evident that the Therm-a-Rest Hyperion Sleeping Bag is a lightweight and compact option with high build quality and a good warranty from the company. However, its performance in cold temperatures and suitability for different sleeping styles may vary among users. **
