Hey y'all, I just recently bought a 17.3 inch HP Pavilion dv7 and I'm in college and I need a REALLY good backpack that will keep my laptop safe and hold all my books at the same time. I've tried browsing on my own but it's all so confusing. By the way, "I'm in college" also translates to "I'm broke," so under $70 would be ideal 
Thanks!
Thanks!
