Durable clear backpack.

Bought on Amazon but never used because I quit the job I needed it for so it’s brand new and had lots of room. There is enough room to fit your coat and some extras with the big zip up part which also has a little zipper inside. Then the bottom part zips out for smaller items such as phones or pens chapstick whatever. And there are two net bottle holders on each side of bag. The bag has adjustable straps to fit any size!
