Putting my Lockit thoughts in here (although I don't own an Epi yet). I looked at Alma and Lockit in the boutique b/c I love the shape of both of them. But the Lockit was small...a lot smaller. I thought I might not be able to get my stuff out without shifting things off the top of the bottom stuff and the stiffness of the zipper...it didn't seem as functional as the other Epi bags. I was disappointed b/c I really love the shape of the Lockit. I know owners seem to love it but many don't use it that often...maybe that's why?
