One, I love how the zippers on the pouches and the Swift open the same direction. It wasn't until I was trying to get into a pouch while still keeping the bag on my shoulder that I realized how nice of a feature this is.
Two, I love how a 4 x 6 photo will just fit in a small pouch. I have a picture of my nephew playing t-ball in the back of one of my pouches, and it never fails to make me smile when I need to get into that pouch. It tucks behind the zipper at the top of the pouch, so I don't have to worry about it getting mixed up with what I store in the pouch, either.
