SnoozeShade is made from a double layer of EziBreez® mesh, and that double layer is where the strongest protection comes from. Wherever it's doubled, SnoozeShade blocks 97% of UV and is rated Most Effective, the top sun protection category for shade fabrics.
On panelled products (Plus Extra, Plus Deluxe and Twin Extra) the zip-up see-out panel opens to a single layer so your baby can see out. Even open, that single layer of black mesh still blocks over 80% of UV and is rated Effective. That's a strong result for a single layer with no chemical treatment, because SnoozeShade's protection comes from the mesh structure itself, not from a coating or finish.
That's why panelled products are described as blocking up to 97%: with the panel closed you get the full figure, and with it open you still get strong protection plus a clear view out.
A note on how we measure UV protection: UPF is a textile standard designed for clothing worn against the skin, and a pram shade sits above and around your baby rather than against them. Australia has a dedicated standard for shade fabrics, AS 4174:2018, which gives a UVE (Ultraviolet Effectiveness) rating, and that's the standard we use. Every SnoozeShade is tested to it by ARPANSA, the Australian Radiation Protection and Nuclear Safety Agency, at their government laboratory.
