Caps offer no protection.
At Palmerston, we have even put large roofs over our two outdoor equipment areas so they are safe all year round. In the yard it is a must, especially during late spring, summer and early autumn. Its very easy to get sunburnt and as someone has already said skin cancer is a big killer here. We are protecting ourselves. Children are also taught in schools the reason for this.
