Both DS1(11th) and DD(6th) are using Northface backpacks this year. They seem heartier than the Adidas bag DS2 is using but also a tad smaller. DS1 has a block schedule with 4 classes a semester so he doesn't carry as much. We have an older Adidas and UA backpack (pretty sure it's been around for at least 6-7 years because DS2 used it for most of elementary and he's in 8th) that still look great while more recently purchased ones ripped and got tossed. They have been relegated to overnight or travel bags now.
