Our primary school backpacks and schoolbags are all made of a technical material that can withstand rough handling! At Jeune Premier, we have always sworn by high end 900 D polyester with Teflon coating. The specific weave and thickness of the polyester ensure the sturdiness and durability of the bag, while the Teflon coating causes rain to slide off our bags like water off a duck! All our products are 100% vegan! No animal products are used in the entire production process.
