I love my Osprey. I visit 1-6 schools per day for work, so it spends a lot of time in my trunk or on classroom floors. I think I’ve had it about 18 months and it shows no signs of wear, despite carrying tools in one of the side pockets- that’s what killed my previous backpacks. I also have a Kipling that still looks great after 10+ years, but i only use it for travel.

For pens, i really like the sharpie rollerballs.
