First of all I thought the bags where going to be a little smaller than expected, I was amazed by the size, they are big enough to fit all of your necessities in order to survive an Angel attack. The bags are really nice construted and feel sturdy enough to withstand medium to heavy usage. As for the zippers they kind of feel like they can break if a lot force is used to open and close them. Great bag/bags overall, I will defenitely recommend this to any Evangelion fan and anyone looking for an orginazable bag!
