Can you persuade Dad to send a check instead so you can shop for the pack yourself? Pack fit is almost as individual as shoe fit, and you really need to try on numerous packs with your gear loaded inside to be sure you get a good fit.

The "90" in that model designator sounds like the thing is 90 liters, which is HUGE. If so, it either means you fill it up and consequently have a very heavy pack, or you have far too much space for what you need and consequently have a problem packing it sensibly, with everything having migrated to the bottom of the pack.
A second vote for allowing you to choose your own pack.
This pack definitely has "my first backpacking purchase mistake" written all over. It is an unknown brand and is absolutely massive. They size it based on your height... not your torso length. If you are a beginner there will be a lot of temptation to pack every fear you can think of (why not throw that in too? sure, I've got plenty of room). You will end up with a poorly fitting pack and 60 lbs of gear you don't need.
Depends on what you want the pack for really, if you want it for carrying a heavy load a few hundred yards, to be thrown into airplane cargo holds, dumped on tarmac, kicked in boarding houses etc it looks fine for that sort of backpacking. If you wish to go long distance or steep gradinents its not really what your after. As stated by others, you havnt tried the fit and its a bit heavy.
