>>2814762The problem is the shoulder strap configuration and lack of waste belt are shit and would be uncomfortable on a long hike. This is literally an overpriced Jan-sport with features you don't really need for using as a school backpack.
A 30 liter daypack (30l is big enough for an over night pack as well) needs a much better strap and load distribution system to be good on long hikes... and this pack doesn't have that.
