The double layer of EziBreez® mesh blocks 97% of UV and is rated Most Effective, the top sun protection category for shade fabrics. That's the same on every pram, stroller and car seat SnoozeShade, whatever the colour.
On Plus Extra, Plus Deluxe, Twin Extra and the car seat shades, the zip-up see-out panel opens to a single layer so your baby can see out. That single layer blocks over 80% of UV and is rated Effective. That's why we say these shades block up to 97%: with the panel closed you get the full 97%, and with it open you still get real protection and a clear view out. The protection comes from the knitted structure of the mesh itself, not from a coating or treatment, so it doesn't wash out.
A note on how we measure UV protection: we've recently updated the way we measure sun protection, on the advice of experts in the field. Like most baby sun products, we've always quoted the UPF rating, and it's a genuine, independently tested result for our fabric. But times have changed and a new standard has developed. UPF is a clothing standard, written for fabric worn against the skin. There is now a standard written specifically for shade fabrics: the Australian standard AS 4174, which gives a UVE rating, short for Ultraviolet Effectiveness. That standard is what we have chosen to embrace moving forward, and every SnoozeShade is tested to it by ARPANSA, the Australian Radiation Protection and Nuclear Safety Agency, at their government laboratory. SnoozeShade is rated Most Effective, the highest sun protection category there is. Most Effective starts at 95%, and SnoozeShade blocks 97% of UV.
