Due to the delicate nature of bamboo, Zipsters are designed to be washed in cold water and tumble dried on low.

Please note that Bamboo is a natural fiber and is delicate; so should be washed separately from items that may be damaging, like towels, hardware or Velcro.

For the longest wear, you can wash them inside out and line dry when possible.

At Zipster, we are true advocates of bamboo and believe it really is the best option for your little one.

Zipsters are therefore made of 95% bamboo and 5% elastane (to provide some stretch).

Bamboo has got so many qualities that lend itself to the perfect choice: 

It's super soft. If you don't agree we'll send your money back.
It's thermoregulatory, meaning it can keep your baby warm or cool.
It's hypoallergenic, so perfect for babies with sensitive skin.
It's sustainable, meaning we're not damaging the planet more than we need to.

Zipsters are made with 5% elastane, so they have a lovely stretch to them and therefore last longer than other baby grows.

We recommend sticking true to size, but if in doubt between sizing, go down. For example, if your baby is 5 months old, we recommend 3-6 months rather than 6-12 months. In most cases, the baby grow will fit until 2-3 months after the top age range.
