Bamboo Care Tips

Our AllDay Zip Rompers and two-piece pyjamas are crafted from soft, breathable bamboo fabric. To keep them looking and feeling their best:

  • Wash in cold water on a gentle cycle to preserve the fabric's natural softness and durability.
  • Use mild detergent. Do not use bleech which can damage bamboo fibres.
  • Wash inside out to protect prints and zips from friction.
  • Air dry whenever possible to extend the life of the fabric. If using a dryer, choose a low heat setting.
  • Check zips before washing to ensure they're fully closed and functioning smoothly.
  • Ovoid ironing  bamboo naturally resists wrinkles. 
  • Avoid fabric softener, which can reduce breathability and affect the fabric's natural qualities.

With gentle care, your SOLBI pieces will remain cozy and comfortable through many seasons of wear and growth.

How to Measure

  • Height: Measure from the top of the head to the soles of the feet while standing or lying flat.
  • Chest: Measure around the fullest part of the chest, keeping the tape measure relaxed and parallel to the ground.

For the best fit, we recommend choosing a size based on your child's current height.
Our pieces run true to size, but bamboo’s soft stretch often fits longer — choose your child’s usual size for a relaxed fit or one size down for a snugger fit; if your child is tall, stick with their normal size. If between sizes, consider the next size up for room to grow. Our pieces are designed with comfort and gentle movement in mind. 🏃♂️
