Ok, help me ladies because I think I may be losing it! Back when these were first released, my SA called & had a small in the saddle color. I went, picked it up & took it home but returned it because it was too small. I SWEAR that small had an EXTERIOR back pocket/zip section (just like the medium does, I know for sure). The ones in stores now don't have any exterior pocket. And, the small seems bigger because I can easily fit my stuff in it...its driving me nuts wondering if they did a re-style since the original launch or whether my memory is worse than I thought...be honest...I'm losing it aren't I?
