Backpack Case Bag

Backpack Case Bag
Which backpack/school bag should I use this year in school (high school male)?

Hi, I found a few bags on eBags that I’m debating on using this year for school. There’s a private sale and it ends tomorrow, so I need to get on the stick! Here’s the ones I’m considering:

For a backpack:
http://www.ebags.com/dakine/101_pack/product_detail/index.cfm?modelid=111796 (in the WOODLAND color)

or

http://www.ebags.com/caribee/tailwind/product_detail/index.cfm?modelid=110778 (in either color, you pick)

or maybe a messenger:

or

http://www.ebags.com/dakine/messenger_bag_lg/product_detail/index.cfm?modelid=111864&rlid=detail_ai&rcode=614750924340798 (in whatever you like)

And if you like anything not listed, PLEASE TELL ME! Thank you!

I like the second backpack in the Putty/Gray
