How to Clean a NEMO Sleeping Bag

Step-by-step instructions

Step 1: Read the label and identify the fill

Confirm whether the NEMO bag uses down, synthetic insulation or a hybrid, and check its size, waterproof footbox, zipper and removable accessories. Follow the sewn label when it differs from general advice. Repair a torn shell or open seam before washing so insulation cannot escape into a machine or tub.

Step 2: Air and shake out the bag

Empty pockets, remove a liner and shake out grit. Air the opened bag in shade and gently redistribute insulation. Many odors improve when moisture escapes. Do not beat the bag, vacuum it aggressively or leave it in prolonged sun; the goal is to remove loose debris without stressing baffles and face fabric.

Step 3: Spot-clean when possible

NEMO recommends spot cleaning to avoid unnecessary full washes. Mix a small amount of non-detergent soap with water to make a light paste, then use a cloth or soft toothbrush on the soiled shell area. Hold insulation away from the wet zone when practical, wipe away soap and let the spot dry completely.

Step 4: Prepare for a full wash only when needed

Wash the entire bag when widespread body oil, grime or persistent odor remains. Close hook-and-loop tabs, unzip the main zipper fully as NEMO directs and remove detachable electronics or accessories. Use a large front-loading washer without a center agitator or hand-wash in a clean tub. A small machine can compress the bag and prevent proper rinsing.

Step 5: Use cleaner matched to insulation

Select a dedicated down wash for down or an approved technical cleaner for synthetic fill, following the label quantity. Do not use ordinary detergent, bleach, fabric softener or dry-cleaning solvent. Run a gentle cycle at the specified temperature, or press water through the bag by hand without twisting or lifting it unsupported.

Step 6: Rinse and move the wet bag carefully

Use an extra rinse when needed until water is clear and no soap remains. Support the entire bag from underneath when moving it; wet insulation and fabric are heavy, and lifting by one end can tear baffles. Press water out gently in the tub or use the label-approved spin cycle, but never wring.

Step 7: Dry slowly and restore loft

Use a large dryer on low heat only when the label permits. For down, clean dryer balls can help separate clusters. Stop periodically to break up clumps gently and check temperature. Synthetic bags may have different limits. Never use high heat, and expect a large bag to require multiple cycles rather than increasing temperature.

Step 8: Confirm the insulation is completely dry

Spread the bag out and feel every baffle, footbox, hood and draft tube. A cool or dense clump may still hold moisture even when the shell feels dry. Continue low drying or shaded airflow until loft is uniform and there is no dampness. Storing partly wet insulation encourages odor, mildew and loss of performance.

Step 9: Store loose and breathable

Close zippers without trapping fabric and place the completely dry bag in its large breathable storage sack, not the small compression sack used for travel. Keep it in a cool dry area away from pests, chemicals and heavy objects. Compress it only for transport and re-loft it soon after returning home.
