Pro Pockets on the hip belt for easy access

Cons
Con Not specifically designed for travel
The J38 is a versatile pack, but not specifically designed for travel. It has some features you may not have a use for (such a pole loops) and is lacking in features you may find helpful (like a laptop sleeve). The shape is not ideal for storage (under seats, or in the overhead).
Con Expensive
Compared to other packs around this size, the price tag on the Gregory is a bit higher.
Con Pocket for hydration reservoir is difficult to access
The pocket for the hydration reservoir is external, located right behind the back panel. There is very little room, making it hard to access and can only fit a small amount of water (around 1.5L).
Con Internal bungee compression system can get in the way
The internal compression straps are a bungee system, which does not unclip the way most do. When your pack is full, this can make it a very tight squeeze if you want to access something in the back.
