With its high-performance synthetic fill and a cut that balances roominess and thermal-efficiency, the Big Agnes Sunbeam 15 Degree Women's sleeping bag is designed for 3-season backpacking and camping.


With its high-performance synthetic fill and a cut that balances roominess and thermal-efficiency, the Big Agnes Sunbeam 15 Degree Women's sleeping bag is designed for 3-season backpacking and camping.

Big Agnes ergonomically tailors its women’s bags to properly accommodate female backpackers and campers. These bags are cut wider at the hips and have a shorter overall bag length to ensure thermal efficiency. Additional insulation in the foot box and the core area of the sleeping bag account for those areas women most often find difficult to keep warm.

The bag’s FireLine ECO synthetic insulation dries much faster than down and provides warmth even when wet. This is particularly important if you'll be backpacking or camping in wet weather or humid climates. This sustainable insulation is also created from 100% post-consumer recycled polyester. Nylon ripstop shell fabric has a surface treatment that further helps to repel moisture and protect the insulation and a soft polyester lining provides next-to-skin comfort.

In a traditional sleeping system, the bag lies on top of a sleeping pad. In this configuration, many people find themselves rolling off the pad at night. Not only that, but the insulation on the bottom of the bag is often compressed by the sleeper's weight and, once compressed, the fill loses most of its insulating properties. The Big Agnes System is different and joins the bag and the pad together. A Flex Pad Sleeve on the bottom of the bag accommodates pads of varying lengths, widths, and thicknesses and ensures that the pad stays beneath you. It also enables the pad to deliver warmth and it allows Big Agnes to save weight and bulk by only lightly insulating the bottom of the bag itself. You'll stay warm and you can roll and move comfortably during the night without ever worrying about slipping off of your pad.

The bag is designed to be used with 20"-25" wide Big Agnes sleeping pads (sold separately) with an R-value or suggested temperature range to match the bag's temperature rating. Big Agnes does recommend using a rectangular pad for optimal performance.

The bag also features a contoured and insulated hood, an internal "barn" to keep a pillow (sold separately) comfortably beneath your head, a roomy footbox, a no-draft collar, and a draft tube behind the anti-snag side zipper. There are internal loops that enable you to use a liner (sold separately) and external loops for drying or storing the bag when not in use.

Available in Petite (fits up to 5' 6") and Regular (5'10") size options, the Big Agnes Sunbeam 15 Degree Women's sleeping bag includes a mesh storage sack and a polyester ripstop stuff sack.
