Perform Fiber Sleeping Bag 19F

What Our Gearhead® Experts Are Saying:

"The Perform Fiber Sleeping Bag 19F is my go-to for cold-weather camping. The synthetic insulation keeps me warm even in damp conditions, and the central zipper helps regulate temperature when the night warms up. I love the soft, quiet hood material and the included sleep mask and earplugs—little details that make a big difference in getting a good night’s sleep outdoors."

After a long day on the trail, we want a sleeping bag that helps us rest and recharge. The Perform Fiber Sleeping Bag 19F is designed for comfort, warmth, and ease of use. Its ergonomic mummy shape and synthetic insulation provide reliable warmth down to 19°F, while the central zipper allows for easy entry and ventilation when we need it.

Beyond warmth, this sleeping bag is all about thoughtful design. The soft hood material minimizes noise for better sleep, while the included sleep mask and earplugs help us tune out the world. With a draft collar to block out cold air and a PFC-free DWR treatment to repel moisture, this bag is ready for alpine starts, crisp mountain air, and multi-day adventures.
