Claire ★★★★★

The extra room around the chest makes all the difference for me—I can move without feeling constricted, but it still packs down small. I took it out on a chilly 40-degree night and stayed perfectly warm the whole time.

Ryan ★★★★★

I was a bit skeptical about a mummy bag having true extra space, but the Swift's design really delivers that roominess without sacrificing warmth. The Muscovy down lofted up beautifully on the first night out.

Leo Y. ★★★★★

The extra room around the chest is a game-changer for me—I can actually shift positions without feeling trapped. Even on a chilly night, the down kept me perfectly warm without overheating.
