I LOVE it. I have used it every single day since I bought it. My typical daily carry includes my phone, wallet, keys, a pen and mechanical pencil, two pairs of glasses, Airpods, a pocket sized notebook, and a water bottle. I just got back from a one-night trip to my parents and carried all of the previous items, plus a larger notebook, single change of clothes, and small toiletry bag and the tote could easily zip close.
I've knocked it into a lot of things since it's a bigger bag than I'm used to, but I haven't noticed any signs of wear. Today I finally received a bag shaper off Etsy and it fits and matches the color absolutely perfectly. I have everything neatly arranged now and am so excited to carry it on Monday back to work.
Now, I will say the particular model I have may require a little more caution. The summer tote has embroidery on the front and a thread came loose from one of the letters. On the inside of the bag where the embroidery is, I pulled the thread tight again and decided to put a little drop of superglue to keep it from unraveling again. So far that's the only little problem I've seen, but most of the models don't have embroidery so if it's a non-embroidery model it shouldn't be an issue.
As far as durability goes, I think this bag will last me a long time. I'm so incredibly happy that I bought it, I am in love with the look and functionality. Here are some pics with the new shaper in it, holding my typical work-day things:
I was thinking of getting the 30 at some point but I think they've priced out the Field totes.
I don't think it has seen the inside of its dust bag since I got it. (So, yes, it came with a dust bag, albeit small compared to the size of the bag itself)
