Two-in-one bag. Jupiter is practical and easy to carry when cycling and walking. It has plenty of reflective surface to light up a dark night. It is designed with room for a 13-inch tablet or computer. The bag converts to a more compact model if you need less space. The shoulder strap can be used on its own without the bag. It is equipped with a zipper and has room for your phone, keys, credit cards and more. Use it in the city, in nature, when you're out walking, cycling, at festivals, etc. Just use it! Our Jupiter Crossbody bag is made from 65% GRS-certified recycled polyester and 35% organic cotton and PVC-free reflectors. The bag is highly reflective and is coated with a membrane that makes the bag water-repellent.
