The reason for the difference in weight is due to the updated materials and construction used in the current model, which provide better insulation and durability.\"\r\n\r\n Given that puts the weight of the Kelty Cosmic Down 20 at about double that of other bags I was considering I will probably scratch it from my list as too heavy for backpacking.
