1. Use the Right Detergent
Down contains natural oils essential for its loft and insulation. It is recommended to use a neutral or specialized down detergent during washing. Avoid using alkaline detergents or dry cleaning, as these methods can strip away the oils, causing the down to lose its elasticity and warmth.
2. Avoid Fabric Softeners
The down structure is filled with numerous air pockets that provide breathability and insulation. Fabric softeners coat the down fibers, blocking these air pockets, thereby reducing the bag's breathability and warmth.
3. Spot Cleaning
For dirty spots, use a soft-bristled toothbrush or sponge with neutral or specialized detergent to gently scrub the stained areas. Do not use bleach, as it can damage the down and fabric.
4. Choose the Right Washing Method
If using a washing machine, avoid machines with an agitator, as the agitator can exert excessive pressure on the down, leading to fabric tears. A front-loading or non-agitator washing machine is safer.
Note! Before washing, inspect the sleeping bag carefully to ensure there are no damaged areas. Close all zippers and secure any Velcro fasteners before placing it in the machine.
Note! When hand-washing, drain the sink and gently squeeze the water out of the sleeping bag before lifting it. Do not lift it directly when wet, as the heavy weight can put excessive stress on the fabric and internal structure, causing damage.
5. Drying Tips
Lay the down sleeping bag flat in a cool, shaded area to air dry, or hang it under gentle sunlight for better results. Avoid exposing it to harsh sunlight (from 11 AM to 3 PM). During the drying process, gently knead or pat the down regularly to restore its loft and prevent clumping or odors.
Note! If using a dryer, choose a low-temperature setting. Add one or two tennis balls or drying balls to help fluff the down and restore its loft. 
Guidelines for Long-Term Storage of Down Sleeping Bags
Down requires space to remain expanded to preserve its elasticity and insulation performance. Avoid keeping it compressed in a stuff sack for extended periods. When not in use for a long time, it is recommended to take the down sleeping bag out and let it naturally expand to maintain its loft and warmth.
If storage space is limited, use a breathable, large "sleeping bag storage bag" to prevent the filling from being compressed and to avoid mold growth.
Helpful Tips
1. Minimizing Down Leakage
The fabric used in our down products is tightly woven to minimize fiber migration (i.e., down or fibers passing through the fabric). These fabrics may also undergo high-temperature calendaring or coating treatments to further enhance down-proofing and insulation performance. However, small down barbs or feathers may occasionally penetrate the fabric, often through the seam.
If you notice occasional down leakage, it is not a defect. Do not pull the down cluster out of the sleeping bag, as this can enlarge the hole. Instead, gently pinch the cluster from the back of the fabric and carefully pull it back inside the bag.
2. Extending the Lifespan of Your Down Sleeping Bag
Down sleeping bags do not require frequent washing, as excessive cleaning can damage their loft and insulation performance. To minimize the need for washing, it is recommended to use a sleeping bag liner. During outdoor activities, sweat, dust, and mud are common, and entering the sleeping bag in such a condition can necessitate cleaning afterward. Using a liner helps keep the sleeping bag clean, reduces the frequency of washing, and prolongs its lifespan.
