I have been using this bag for almost two years now and I can definitely say it's the best bag I have every bought. I use it everyday for work and it's durability is amazing. When I'm not using it for work it's perfect for travel, I have an upcoming European vacation soon and plan on taking this bag with me. The locking clips that secure the flap gives me peace of mind from items falling out. I am very satisfied with Manhattan Portage!
