Big Agnes Roxy Ann Sleeping Bag

The Roxy Ann uses a two-piece system—a contoured inner bag and a rectangular outer shell—that you can use together for maximum warmth or separately depending on the temperature. This allows you to adjust your sleep system for different seasons without needing to own multiple sleeping bags.

Yes, the semirectangular shape provides more room than a traditional mummy bag, making it much more comfortable for side sleepers. The integrated pad cinch system also helps keep the bag centered on your sleeping pad so you don't roll off during the night.

The 15°F rating is a comfort-limit guideline, meaning it is designed to keep you warm down to that temperature when paired with an appropriate insulated sleeping pad. If you tend to sleep cold, we recommend using a pad with a higher R-value to ensure you stay comfortable near the lower limit.

The 650 DownTek insulation is treated to resist moisture, meaning it retains its loft and insulating properties better than untreated down if it gets damp. While it is not waterproof, it offers a significant performance advantage over standard down in humid or condensation-prone environments.

The pillow barn is a dedicated sleeve or pocket at the head of the bag designed to hold your pillow in place. It prevents your pillow from sliding off your sleeping pad or migrating to the bottom of the bag while you move around at night.

At 3.31 lbs, this is a versatile choice for backpacking, though it is slightly heavier than ultralight mummy bags. Given that it replaces the need for extra layers or a separate liner, many backpackers find the weight trade-off worth it for the increased comfort and modularity.
