Kelty Cosmic

The 20-degree rating indicates the lower limit where the average user should remain comfortable, but it is not a guarantee of warmth. If you are a cold sleeper, you will likely be most comfortable in temperatures closer to 30 or 35 degrees, especially when paired with a quality sleeping pad.

Yes, the Kelty Cosmic 20 uses treated down insulation, which helps it resist moisture better than untreated down. While it performs well in damp conditions, it is still important to keep your bag dry and use a waterproof stuff sack when packing.

When fully compressed, the bag has a volume of 12.5 liters. It is designed to be packable for a 3-season bag, though it will take up a significant portion of a smaller daypack.

Yes, the bag is designed to accommodate users up to 78 inches, or 6 feet 6 inches, in height. If you are near this height, you may find the fit snug, but it provides adequate length for most tall individuals.

The draft collar is an insulated tube that sits around your neck and shoulders to seal in warmth. It prevents the heat generated by your body from escaping out the top of the bag, which is essential for staying warm on nights near the 20-degree limit.

Mummy bags are inherently more tapered than rectangular bags to maximize thermal efficiency, which can feel restrictive to side sleepers or those who toss and turn. However, the Cosmic 20 is cut with a slightly more spacious shape than some performance mummy bags to allow for more natural movement.
