i'm looking for a backpack to replace my lululemon one, it last me almost 5 years it's still in usable condition but since i'll be hauling a new laptop, might as well get a new bag to go along with it i'm looking for a bag that i can use for school but for sports as well. i like the look of the incase ones but they don't really offer much in terms of space and versatility. my 2 main needs are padded laptop compartment, preferably separate from the main pocket, and a water bottle pocket. another plus would be something spacious (mid-20L). i've looked at a few and most don't meet all my needs. do you guys have any suggestions?
