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 Uncomfortable to carry for long periods
Not a great option if you're looking for a pack you can wear while exploring the city.
There is no hip belt or hip strap, so all the weight of the pack will be on your shoulders. The shoulder strap padding is fairly minimal, causing them to dig in.
