I love this bag.  Its design is well thought out.  It’s seems like they heard me when I said out loud “I want leather, no lining, a pocket for my phone & I don’t want it falling off of my shoulder when I bend down to pick something up…”    This bag has just enough room for my wallet, lipstick, eyeglasses in their soft case & a tiny moleskine soft cover notebook.  I’m so happy with it as far as design.  
It’s a throw on and go while looking great.  Sometimes the zipper does not close and open smoothly, but I think it’s just the crescent shape that makes that inevitable.  I don’t mind it, just something I noticed.
I ordered the brown leather & when I pulled it out of the package, I noticed two tiny black dots on opposite sides of the front of the bag.  Very noticeable.  It looked as if someone had a fine tip sharpie and added a final touch before sending it to me.  It really bothered my “I need things to make sense” personality, but I didn’t want to make a huge deal of it by complaining.  I decided to attempt to remove the dots myself with a high end  leather cleaner I had.  I didn’t make it better.  I still love my bag, oh well…. It’s my own fault messing it up a little trying to remove the black dots.
I would like to put the olive green sling xl  on my birthday wish list coming up.  It looks like a gorgeous color that could still work as a neutral.
