I think the whole design is good and stylish.
Costing $560 with this quality is surprising, no matter the waterproof, the material used or the storage is well done.
I love this sturdy, but there are still some areas I think it can be better.
First, if there can be two inside pocket for both the umbrella and the water bottles, it would be much better. There are only one water bottles pocket inside.
Second, if the handle on the top can have more cushion, it will be greatly appreciated.
Under this price range, I think the sturdy is one of the best bag available in the market, and also, I love this brand too. Price is affordable, the design is stylish and most importantly, it is a HK brand.
