My black Epi PM Alma is my rainy day bag, too! I love the size and the form factor, the double zipper, the fact that it has feet. I've been thinking about branching out in Bolides and have been wondering what size to start with.
I bought a strap for my PM Alma but, have not used it all that much. I think the bag is too bulky for crossbody or shoulder wear. The strap I have was the one that was available back when I first bought the Alma. I might try again with a wide woven strap. I would love to have a smooshy, softer Alma and was ready to make my move on the Neo just when it was discontinued. Another reason to consider Bolides.
