What is Penumbra? Penumbra is essentially the light that surrounds the dark, a term most used in astronomy to describe the shadow of an eclipse. With this in mind, we've teamed up with designer Steven Arcella to create these limited edition tees just in time for the 2017 August eclipse! 

All of our shirts are hand-printed on Next Level unisex tees by Kingsland Printing in Brooklyn. Made with glow in the dark ink on 100% cotton tees. Shirts made sweatshop free, here in the USA. Go and glow in this Penumbra tee! 

All of your proceeds go to help support our programs.

Available in unisex sizes: S(Sold out), M, L, XL(Sold out)
Sales tax included in the price.
