Cassidy Satchel, in Koala Matte Nickel, available at Matt & Nat, $155
A structured satchel with a sturdy top handle and a removable (and adjustable) crossbody strap makes this the perfect bag for toting your laptop to and from the office. It's also equipped with plenty of smaller pockets meant to fit your iPad, smartphone, and other little items. Not only is it functional, but the minimalist style and neutral color gives this a polished look that's office-ready.
Matt & Nat says it uses a variety of vegan leathers, including both PU and PVC. While those may not be the most sustainable materials around, the brand makes a point to use more eco-friendly materials like recycled nylons, rubber, and cork in its designs too. Additionally, the lining of this bag (and every Matt & Nat bag, in fact) is made of 100% recycled plastic bottles.
