I love it!
I was able to fit (1)Another Case Logic bag with 2 camera lens and a DSLR inside it,(2)a 15.6" laptop,(3) a pair of headphones, and (4) a couple of writing notebooks. Yes, all of those without making the bag look like its going to explode.
I also have tried already filling this bag to its limit, and I never had any problem with it. It has been with me for like 7 months now, and up to this day, it has never stopped to amaze me.
Take note. I bring a camera with 2 lens with me and a laptop everyday, and the bag never fails to protect it for me. I remember this bag falling once from a table with my laptop on it, and the bag receiving the shock for my laptop.
If you're going to bring your laptop everyday through the chaos of everyday commuting, I highly recommend this laptop.
This is my 3rd bag from Case Logic, and this is also the 3rd time I am amazed. Looking forward to buy a small commute bag from Case Logic in the future! :D
