I only like the shade when you're blocking the light.
We live at 7,000' above sea level and spend most of our time outside. Over my past 17 years living at altitude and in the mountains I've learned the importance of covering up my skin. Some spots are just impossible to cover.
Mineral sunscreen or physical sunscreen puts a layer of actual minerals blocking the harmful rays into your skin. This is food-grande non-nano zinc and will turn your skin a bit on the white side, but for the most part rubs in pretty nice.
The cardboard packaging is to be a bit lighter on the carbon footprint and can be recycled in your home compost!
SPF level is about 25 and this should be reapplied every 2 hours or every hour if you are sweating.
Be safe and go get it!!
