Quick answer

Machine wash your Zipadee-Zip on a gentle cycle with cold water and mild detergent. Tumble dry on low or air dry. Avoid fabric softeners and bleach to protect the fabric and zippers. Wash every 2–3 days or when soiled.

Why proper washing matters for your Zipadee-Zip

The Zipadee-Zip is designed to be a safer sleep solution for babies who start to wiggle and roll. The unique starfish shape and double-zipper construction rely on fabric integrity and zipper function. Harsh washing can degrade the bamboo or cotton-poly blend, cause pilling, or damage the zippers. Following the right care routine keeps the sleep sack soft, safe, and effective for months of use.

Step-by-step machine wash guide

  1. 1. Close all zippers and turn inside out: Zip up the main zipper and any secondary zippers completely. Then turn the Zipadee-Zip inside out. This protects the zipper teeth from catching on other laundry and keeps the outer fabric from pilling. Common mistake: washing with open zippers can snag and break the zipper. Always double-check before loading.
  2. 2. Use a mesh laundry bag (optional but recommended): Place the turned sleep sack in a mesh delicates bag. This adds an extra layer of protection, especially if you wash it with other items like onesies or towels. It also prevents the wings from getting tangled. Checkpoint: If you skip the bag, make sure no other items have hooks, buttons, or zippers that could catch.
  3. 3. Select gentle cycle with cold water: Set your machine to a gentle or delicate cycle. Use cold water only—hot water can shrink bamboo fabric and weaken the elastic around the armholes. Add a small amount of mild, dye-free detergent. Common mistake: fabric softener and bleach break down the fabric's moisture-wicking and softness. Avoid them entirely.
  4. 4. Tumble dry on low or air dry flat: Remove the sleep sack from the washer and check for any remaining twists. Tumble dry on low heat or air dry flat. High heat can damage the zipper plastic and shrink the fabric. If using a dryer, remove it while still slightly damp to prevent over-drying. Checkpoint: Never wring or twist the wet Zipadee-Zip—it can distort the starfish shape. Gently reshape and lay flat.
