Not too big. Not too small. Nova is perfect for your actual essentials (hand sani, keys, wallet, phone, etc.) With multiple pockets and sleek storage, this lightweight sling bag also fits other items you deem essential (perhaps an umbrella, book or hat â your call). Made from RepreveÂ® recycled polyester created by repurposing 7 recycled plastic bottles, Nova is definitely a friend to Mama Earth. This eco friendly sling bag comes in three colors, is super stylish, and goes with whatever youre wearing. Oh, and the dust bag? Thats made of 4 recycled plastic bottles.
