Seattle Seahawks and Mariners and Sounders FC backpacks for game day, back to school, or for every day that you want to carry your gear in style. Of course for the Seahawks, you can now only bring clear bags to the game so we’ve got a clear Seahawks backpack for game days. At this time you’re still good to go at Mariners games with your favorite backpack. I’m hoping to add Sounders backpacks soon, so check back if you’re a Sounders fan. Whether you’re a Seahawks fan or a Mariners fan or like me you love all our sports teams, you’ll love these great backpacks.
