Down is the best filling material when it comes to making a sleeping bag. None of the synthetic fibers created by men can compete regarding insulation, loftiness and lightweight. All the down that is used in textile and outdoor industries is a by-product of food industry, meaning no animal is farmed in the only purpose of using its down.
Down being a by-product, the down companies had to develop an all-encompassing certification system to make sure their products will meet the highest level of transparency and traceability. To follow the Responsible Down Standard®, the down must not come from animals that have endured unnecessary harm, such as live-plucking or force-feeding. This standard provides traceability from the farm where the animal was raised to our product you are using.
Although we don't have a certification, Freetime commits to using only R.D.S. certified down.
