At a glance the Slingshot doesn't look any wider or longer than the similarly sized Jester, Sweeper and Vault day packs from The North Face--and it isn't. The reason that the Slingshot offers more space is that it has over two inches of extra expandable width along the sides, giving it a carrying capacity of 2,000 cubic inches instead of the standard 1,850. The North Face also attached side compression straps to the front trampoline system so you can cinch down that extra width when you don't need it. All that extra load potential and control adds an additional five ounces to this pack compared to the slightly smaller designs, but you're not going to notice a difference when you're hauling around eighteen credits worth of reading material. If you're staying late at the office or library, the Slingshot also has plenty of reflective elements, so you have a better chance of being seen by passing motorists (or your workaholic boss).
The best
I had a hard time figuring what Northface backpack I wanted for College, I found this to be the best backpack for its price and is not to big, I love it and will never get another.
Perfect size
It is the perfect size for lots of textbooks and the padded straps help offset the weight of the books!
Cheap and great!
I bought it in the Woodbury outlet near NY only because it was very cheap (I'm italian and in Italy North Face is very expensive), but after a few days I discovered that it is really great! It's perfect for weekend trips and it's so big inside that you could use it as luggage!
