What are the Pros and Cons of Down Insulation?
The pros are its higher warmth-to-weight ratio that is very compressible and durable under the proper care. The cons are its insulating power is reduced when it gets wet and takes lots of time to dry. It is not hypoallergenic (but that is rarely an issue), and cleaning requires extra care (due to long dry-up time). Of course, it is more expensive for a reason.
