I tried it as well but it's just awkward as a crossbody IMO. I thought the Alma/BB would be worse, but it's actually way more well suited to me than the Metis. I've never worn crossbody bags but have bought several recently and am really enjoying how easy-to-use and convenient they are. Freeing up my arms, hands and shoulders, I'm discovering, is amazing!
Oh, and the nano Noé. Sorry but the thing is just useless unless you're a little kid. It won't even hold a wallet! My car keyfob with its luggage tag key holder, card case and tube of lip balm filled it up and it looked silly on me, it's so tiny. Fortunately it was a gift and i got to exchange it with the giver never knowing
