What is Nanotechnology?
Nanotex changes the fiber on a molecular level, so it permanently resist spills and stains. The change in surface energy keeps moisture on the top of the fabric, instead of sinking in or staining.

Is it fire-retardant?
Yes, Nanotex fabric is fire-retardant. 

Is it machine-washable?
It’s best to hand wash and air dry your Nanotex cover to ensure the quality of the product is maintained for the life of the seat.

What is recommended cleaning solution?
We recommend using ½ Tsp of a mild detergent like Dreft®, to 1 cup of water.

Are there more chemicals in the Nanotex fabric? Is it less safe on my baby’s skin?
Nanotex does not contain or emit harmful substances, and its silver ion technology protects against the growth of odor-causing bacteria. It is free of heavy metals, phenols, phthalates, odor and skin sensitizers, PFOS and PFOA. It does not cause skin irritation or pose a threat to air quality.

Is Nanotex just on the fabric of the seat, or is it also on the harness?
The Nanotex fabric can be found on the stroller and car seat covers, the infant car seat boot and canopy, the stroller canopy and storage basket.

I already have a Britax car seat, can I buy a Nanotex cover set to use on my car seat?
No, the Nanotex Collection is a limited-release fabric available exclusively for our Brixy retail partners.

Does the Nanotex fabric keep my child cool and dry?
The Nanotex fabric is moisture-resistant, making it easy to wipe away spills. The main benefit is to prevent stains from setting into the seat.
