I don't know that particular bag, but bags that size usually go over the airline weight limit even if lightly packed.
After trying a number of different styles over the years, I ended up with
that. It's large enough for all my cold water gear (TLS350 drysuit + backplate), is the correct weight for airlines once full (give or take a couple pounds), and is small enough it isn't a problem to store on boats.
That said, if you don't plan on traveling by air or bring your bag on a boat, there is no such thing as too large a bag.
