Spotter 600 by Cumulus

A sleeping bag and a down jacket
The Spotter 600 by Cumulus is more than just a sleeping bag; it's an all-in-one basecamp essential. This innovative 3-season sleeping bag is created to move with you and adapt to your needs. Two zippered, down-insulated armholes allow you to keep your upper body warm while using your hands freely, perfect for making dinner at camp or taking that perfect photo. When it's time to move around, the footbox folds up and secures with a buckle, transforming the Spotter into a wearable layer that functions almost like a down jacket. Filled with premium 850 Fill Power Polish goose down, the Spotter lets you leave that extra layer behind without sacrificing comfort.
Features:
- Mummy shape provides maximum thermal comfort when sleeping or wearing
- Transform this sleeping bag into a warm down jacket by clipping the footbox with the smart buckle system
- Two zippered functional armholes with down insulating baffles let you extend your arms outside the sleeping bag without leaving it
- H-shaped chamber design that allows down to fully loft, eliminating cold spots
- Full length, 3mm YKK® zip with two self-locking sliders
- Two down-filled zip insulating tubes
- 3D-shaped, jacket-like hood design
- Advanced foot area construction for better protection
- Footbox can be opened and vented
