jansport trans backpack been using for ten years+, cost like 30 bucks, middle compartment is water proof to the point of spilling my gym shake in it and being able to dump it back into my sippy cup, yes I drank it... lol
ogio duffle bag I use for travel, med size I can fit 1-2 weeks worth of clothes depending on shoes. 50-70 bucks I think, had this for 8 years.
both have been around the world with me.
