It looks very attractive, durable, have not had a chance to abuse it yet, but i believe Patagonia always makes great product. 45L is a bit small, maybe good enough for gym or day trip but you need to have a 90L for a couple of days out of town.
Love the tough, waterproof fabric construction, two internal mesh pockets & padded bottom panel. Would have preferred a shoulder strap option, but the haul loops at each end are sufficient. Overall, a well-constructed, decent-sized, stylish & durable (so-far) overnight bag.
