    That allows us to be control freaks in the best way possible; we have direct control and oversight of the quality of our materials, our products, and the jobs and working environment that we help create. It also offers us a unique spontaneity: when we have an idea for a new product or accessory, we can design it, figure out how to build it, add it to our website and be ready to ship it out our front door all within just a few weeks.

The Luminary 15 (L15) is the bigger sibling to our popular Luminary 12 (L12) backpack. To better fit taller and/or broader folks, we took the L12 and stretched it to be taller and a tad wider. We also lengthened and adjusted the contour of the shoulder straps. Otherwise, feature for feature, the L15 and the L12 are the same, so we ask in advance for your forgiveness if the product description below seems a bit familiar.

Like we said, the Luminary 15 is approximately 15% taller, 10% wider, and an inch or two more in depth (as it projects away from your back) than the original Luminary 12.

You’ll get more capacity from the L15 of course (approximately 15 liters vs 12 liters) and you’ll be able to carry a slightly larger device in the back padded device pocket of the L15. The 13” MacBook Pro fits great in the padded device pocket as does the Dell XPS 13. 

While we designed the two sizes to best fit different sized people, we know some will choose the L15 simply for its greater volume, and in most cases, this will be just fine. The Luminary 15 fits a far greater variety of people than the Luminary 12, which is primarily designed for those who are petite. We’ve provided a few pictures of a variety of people wearing both sizes to help you choose between the L15 and the L12; if you’d like additional help figuring out which size is best,

The Luminary is an everyday bag intended primarily to be a small backpack for adult humans. It's designed for an evening on the town, a day spent at museums, the commute to work and back, and traveling the world: wherever you go, the Luminary has your back.

Though the design may look straightforward, its simple lines hide its subtleties. While on first blush the Luminary appears to have a single compartment, its long zipper with four sliders actually accesses the main compartment as well as two side pockets. Both side pockets are sized generously to fit most smart phones and even the iPhone Plus or the HTC U Ultra: you can carry your phone in one and your wallet/keys/personal minutiae in the other. One side pocket is a bit taller than the other, allowing it to accommodate bigger phones/phablets; this makes the main opening a bit asymmetrical, but that’s OK, we promise. The side pocket zippers now close to the top (rather than to the bottom, as did the original Luminary); the juncture where the zipper goes from main compartment to side pocket closure now features a small fabric “garage” to better seal contents from the weather. Both side pockets have O-rings so you can tether keys, multi-tools, Organizer Pouches, whatever.

Handy too is the largely inconspicuous zippered padded back pocket that is sized to fit a tablet or small laptop (see below). Your device is protected by the 1/4” / 6mm foam back padding, yet is easy to access via the exterior, vertical zipper. Inside the main compartment is a zip-away stretch mesh water bottle pocket/divider: when zipped into place, the divider creates three vertical spaces to help you organize your gear and control the load. If that’s not your idea of a good time, leave the divider unzipped and push it out of the way. A small (read: very small) pocket inside the main front panel has been added by popular demand: Nik’s Minimalist Wallet, tiny notebook, pen, lip balm, not more.

The shoulder straps are gracefully curved and feature soft knit edges and undersides; they are padded with 5/16” / 8mm thick EV50 closed-cell foam. They may be the most comfortable shoulder straps ever. The top handle/grab loop is our new soft handle webbing: easy on the digits but isn’t padded and bulky. A 3/4” / 20mm sternum strap and 1” / 25mm waist strap are there if you want them and easily removed if you don’t.

We’ve opted to make the exterior back panel from the same fabric as the rest of the bag. Some users may find it not as cool as our spacer mesh back panels, but as we did not intend this bag for serious aerobic activities, we chose instead to keep the aesthetic simple and the design elegant. 

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 either Luminary this way. Why? The shoulder straps of the Luminary 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 your Luminary 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 may tend to splay widely apart: you might think that the sternum strap will fix this, but the sternum strap will likely be too high on the strap to sit anywhere near your sternum. 

The Luminary 15 is designed to carry a slightly larger device in the back pocket than the Luminary 12 can accommodate: the 13” MacBook Pro and the 13” Air will squeeze in, though you may find you’ll need to do a two-point turn to get either in position (note: that’s without any protective sleeve – add a sleeve and these laptops will not fit). Slightly larger laptops in their respective Cache sleeves  (or other minimalist sleeve/case) will fit loose in the main compartment of the Luminary (note that the bag itself does not have rail loops for the Cache). How about a 15” MacBookPro? Pfft – no way.
