I like OGIO bags. They make great bags, some with roomy padded laptop pockets. OGIO metro gets the job done for me.

 

Ive been using a patagonia bag for years in fact they just replaced a broken zipper on my 4 yr old bag.

 

Jansport is good, they aren't that much in price compared to other bags... and it seems u can really load them up. I blow through bags like crazy too, idk if its the way i carry them or what but they just don't last for me... however my jansport is still hangin out with me from sophomore year of high school, and im in my 4th year of college

 

I use a Jansport Agave 32 backpack for my motorcycle trips. Fits everything I need for college, work, travel, and work. I love the padded curved shoulder straps which helps my arms from being pinched after wearing it for so long. Plus the shoulder strap buckle and belt buckle keep the backpack straped to me.

 

I just ordered one of these:

MotoCentric Mototrek Backpack

I'll post up my impressions once I have it in hand...

Quite expensive, but the best quality I have seen in a backpack and waterproof. Can also buy a hydration pack at a later date. Does not feel like you have it on after 5mins.

I have the hydration pack, backpack and us5. I can use them all individually or combine as one backpack.
