I have been using this bag almost daily for 7 months now and it has traveled about 12,000 miles in flights and I'm still just as happy with it as the day I got it in the mail!
Here is why I love this bag. It's just large enough to fit all you need for the day, yet small enough to fit right at your hip to keep all your important stuff close to your body. Plus it is super easy to open with one hand (essential when you have a 1 year old) and can adjust to fit a little more if I need it. I can fit my wallet, iPhone 6 plus (with a case! I put it in the back-slit pocket) keys, gum and two lipsticks.
I like to carry this when traveling (fits passports easily - I've carried 3 in it at a time) because I can keep all the important stuff like money and docs really close to me. I also love it because it fits easily in the simple tote as I need to carry more I just put this inside and don't have to switch out everything. Daily, I carry this with my diaper bag on my back which is so convenient. Finally, I remove the shoulder strap and love to use this as a simple clutch for a date night or to fit it inside a larger purse as my wallet.
The leather is exceptional. It's lighter and is softer than any of the other bags I have. It will get some markings as you use it (or beat it up as I do) but I like that worn-in, I've traveled before kind of look.
This is a great bag at a great price - if you're on the fence just get it - you won't regret it!
