From the backwoods of Pennsylvania to the hills of West Texas, the Kelty Rambler 50 Sleeping Bag offers a cozy night's sleep on warm summer evenings. Cloudloft insulation maintains warmth while packing down efficiently when you're traveling around the country. The semi-rectangular design offers a roomy feel, so you're not tossing and turning throughout the night. As a bonus for sweltering summer nights, the Rambler 50 unzips into a blanket when a traditional sleeping bag threatens to suffocate your body.
