Despite this, reviews testify to its high-quality Venture-weave polyester and leather build and its excellent organizational features. The laptop compartment can comfortably accommodate a 15-inch laptop inside.

Its compatibility with 100% of airlines also makes it a safer bet for seamless travel. The STM Prime's laptop compartment is sized for a 13-inch laptop, which while being not as spacious as the Classic Backpack Plus's compartment, still works well for most laptop sizes commonly in use.

The former, with its superior capacity and size, suggests a great option for those needing to carry a good deal of items, while the latter offers the convenience of a compact, lightweight, and universally airline-compatible backpack.
