Get the measurements of the bags and compare it to the MBP dimensions.
Id say yes to both
Backpack
Main Compartment: 18"(H) x 9.5"(W) x 4.75"(D)
15" MBP
Width: 14.35 inches (36.4 cm)
Depth: 9.82 inches (24.9 cm)
Should be able to squeeze 9.82" into 9.5" don't you think?
Do you think the measurements on the bags are probably "loose"?
In other words have a little flex or room?
