New for Winter 2025/2026: The Petrel 10 UL gets all-new Pertex® Quantum Pro® shell fabric + Pertex® Diamond Fuse lining fabric in the footbox, plus new and familiar colors

Our warmest three season bag for the female adventurer. Based on the ideas of our testers, the bag features extra fill in the footbox and chest while maintaining a sleek profile and light construction to maximize the warmth from the 950+ fill down. The Petrel is not only an excellent choice for spring and fall adventures, but also a popular summer bag for the coldest of sleepers and a longtime favorite for summer climbs of Mount Rainier.

UL: Ultralight. Pertex® Quantum Pro® water-resistant/breathable fabric with 950+ Fill Power Down

Hazel ★★★★★

I’ve used this bag for a few chilly nights, and the Pertex Diamond Fuse lining in the footbox really keeps my feet warm without adding bulk. The new shell fabric feels durable yet light, perfect for backpacking trips in variable weather. It’s easily my go-to for late-season camping now.

Miles ★★★★★

The Pertex Quantum Pro shell feels noticeably tougher than my old bag's fabric, yet it still stuffs down small enough for my pack. Took it out in 40-degree nights and stayed perfectly warm, the Diamond Fuse lining in the footbox is a nice touch for cold toes.

Timothy Q. ★★★★★

I was pleasantly surprised by how light it is—barely noticed it in my pack. The Pertex Diamond Fuse lining in the footbox adds a nice touch of warmth without extra bulk. Perfect for chilly nights without overheating.
