Delivery times - why are longer delivery times?

Every customer wants to receive his new "dream sleeping bag" in a top quality. In this case, the down filling should not be compressed for a very long time by the packaging and storage in order not to impair the natural buoyancy of the down. Therefore, high-quality down sleeping bags from well-known manufactures are only filled with down at the time of ordering. This ensures that every customer gets a "hand warm" sleeping bag in top quality.
