kelty CATENA 30

The Kelty Catena 30 is a rectangular sleeping bag built for car camping and casual backpacking rather than weight-conscious trekking — at 1.81 kg with 1.2 kg of CloudLoft synthetic fill, it's on the heavy end of the category, but that bulk buys a genuinely roomy cut (174 cm shoulder and hip width) rather than the tapered fit of a mummy bag. The manufacturer-rated limit temperature is -1°C (30°F), placing it as a 3-season bag for spring through fall use rather than winter trips. Sewn-through horizontal baffles and a full-length right-side zipper keep construction simple, and the bag skips a draft collar or hood, relying only on a draft tube along the zipper for warmth retention — typical of budget rectangular bags. Its most distinctive feature is the coupleable zipper: two Catena bags (or compatible Kelty models) zip together into a double-wide quilt, making this a practical choice for car-camping couples or families rather than solo ultralight use, where its near-2 kg weight would be hard to justify.
