Summer is rolling in here and I have to do a lot of walking on a school day due to drop off before work, so I want to get one of those backpacks like @plasticniki’s crew wear that sit elevated from your back.
However, I seem to have only found either ones for cyclists which have no chance of carrying my 15.4" work laptop plus bits or ones for hikers that are massively OTT.
Currently I have a Crumpler Private Surprise L which has a good size:
