Nothing more then GREAT! Excellent Product, fits my needs and protects both MacBook and iPad
I use the Large Drop Pocket & the 13" laptop sleeve in my medium Zero Messenger Bag. It's a great combination. The drop pocket allows me to organize a lot of small objects that would otherwise be laying in the bottom of the bag. I don't use the laptop sleeve for a laptop. I find it's useful for holding file folders & magazines. It protects the files & magazines from being "beat up" by heavier objects in the bag. I use the Strap Pad & it is very comfortable.
I've gone through a lot messenger bags over the years so I have a pretty good feel for when something is well made or is going to fall apart within the first year. This laptop sleeve looks seems as though its the former. Good construction, snug fit for my13" Macbook Air and just enough padding to keep it safe. The liner also seems like a very good material. The sleeve fits perfectly in my zero messenger (medium). Only complaint (if any) would be that the velcro doesn't perfectly line up with the velcro in the bag but it's pretty darn close. Also wish there were color options to match the bag.
