Stuff that's good to know:

Some folks are inclined to wear smaller backpacks low on the back by adjusting the shoulder straps to their maximum length. We don't recommend wearing the Luminary 12 this way. Why? The shoulder straps of the Luminary 12 are designed to conform to one's neck and shoulders when it’s worn relatively high on the back, y'know, like a proper backpack. If you let out the straps and wear the Luminary 12 low on your back, the padded portion of the straps won’t be adequately long, and the adjusting buckles will likely poke you in the wrong place. Additionally, the curve of the strap won’t ride correctly over your shoulder and the straps will tend to splay widely apart: you might think that the sternum strap will fix this, but it’s now too high on the strap to ride anywhere near your sternum.

If you’re a tall person, you might find that the above issues happen no matter what. Do not despair: just make your way over to the Luminary 15 page.

The Luminary 12 is designed for folks who carry a tablet and/or phone as opposed to a larger laptop, and the tablet is meant to be carried in the padded back pocket of the Luminary (it fits tablets up to the size of the 10.5" iPad Pro.) While laptops up to the size of the 12" MacBook or 11" MacBook Air in their respective Cache sleeves will fit in the main compartment of the Luminary, the bag itself does not have rail loops for the Cache. We do not recommend trying to fit laptops larger than the 12" MacBook in the Luminary 12.
