Peak Design has a sale going on their newish roller bag which knocks the price down from stupid expensive to really expensive. I decided to take the plunge as I needed a new bag for some upcoming summer travels. I have to admit, it's really great! The wheels and extendable carbon fiber trolley handle are ridiculously smooth, and I really like the layout inside with lots of spaces to hook things in and tie them down. It looks great and I like that you can keep it really slim or expand it out as needed. My only gripe is the outer "laptop" compartment which really should not ever be used for a laptop; it doesn't provide nearly enough protection. I honestly wish they'd given that space over to more internal storage. I do not recommend getting this at full price, but on sale it makes for a really nice (if pricey) bag.
