Tom designed the Paradigm (you're here now) and Zeitgeist specifically for folks who’d been asking him for years to design a small backpack PLO (Purse-Like Object; read about the origin of that acronym in the Forums).
Both backpacks share the same main compartment: a slightly teardrop shape with a zipper across the top and down the sides. Same shoulder straps too – a new style of strap offering a gentle contour and a touch of padding. Both have the same padded back panel with an interior padded sleeve suitable for a iPad or similar (sound familiar? It’s a scaled down version of the back panel of the Paragon).
After that, the Zeitgeist heads in one direction and the Paradigm heads in another…
The Paradigm has exposed #8 YKK RC DWR zippers on both the main compartment and the front pocket. And the Paradigm’s front pocket has a lot of good stuff going on, so take a deep breath and read carefully on. First of all, this pocket is a full 3D pocket, having on its own a volume of about 2.7 liters / 165 cu.in. It’s divided vertically into three sections: if you fully unzip the top of this pocket you’ll be peering down into all three of the sections, but if you only want access to one of the sections then you can simply move the two zipper sliders around in such a way as to only expose that section (much easier to do than to describe!)
Naturally, you can put whatever you want into these three compartments, but the center one is perfect for a small water bottle or mug: remember, keeping your water bottle dead center makes for a more balanced load. Alternately, that center section can be great for a compact travel umbrella — we added a drain grommet at the bottom for that use.
Lastly, on the interior back wall of the left and right (but not center) sections of the Paradigm’s front pocket are simple open top flat pockets – nice for wallet or smartphone.
Walk through the features of the Paradigm.
3D Front Pocket
This pocket is a full 3D pocket, having on its own a volume of about 2.7 liters / 165 cu.in. It’s divided vertically into three sections: if you fully unzip the top of this pocket you’ll be peering down into all three of the sections, but if you you only want access to one of the sections then you can simply move the two zipper sliders around in such a way as to only expose that section (much easier to do than to describe!)
Contour Backpack Straps
Our new Contour Backpack Straps were designed to be an upgrade from basic webbing straps. They have minimal foam padding to bump up the comfort factor, while remaining light and proportional to smaller or lightweight packs.
Tom developed the shape and fit of the Contour straps over several months, asking for feedback from friends and crew of all heights and sizes — many different refinements were made to the shape and fit. The result? While no backpack strap design is likely to work for everyone, it’s surprising to all of us how many of us love these straps in particular — folks ranging from 5’0” to 6’0” find them comfortable and well-fitted.
Smooth Back Panel
The back panel of the Paradigm is always smooth 525d ballistic nylon in Black, no matter the main exterior fabric or color.
Padded Device Pocket
The Paradigm's padded compartment offers just-right padding without adding bulk or weight. Don't plan to carry a device? Know that most of the padding and construction of the compartment would be there regardless to offer comfort to your back and structure for the bag itself.
The Paradigm will fit devices up to the size of the 11" iPad Pro or Samsung Galaxy Tab S7 (but notably not the S7+).
We added a simple webbing grab handle to the top of the Paradigm. It'll come in handy if you'd like to hang the pack on a coat hook, grab and hoist it up onto a table, or carry it briefly by the grab handle itself.
We include the following accessories to give you a good amount of options for your new bag right out of the gate.
One 8-inch Black Webbing Snaphook/Snaphook Key Strap
A Key Strap is a strip of webbing with plastic snaphooks on the end. The 8” Key Strap in Black that’s included in most of our larger bags is, for many, the gateway to a world of organization via Key Straps and Organizer Pouches. All the members of the Key Strap family are intended to make locating things in your bag easier and more instinctive. Pulling out a small item or pouch tethered to a strap is easier than rooting around aimlessly in the depths of your pack; you can also rest assured that anything hooked to a strap is much less likely to fall out or otherwise be left behind. You can find more Key Strap colors and varieties on the Key Strap page.
One Cord Zipper Pulls w/ Plastic Ends (8-Pack)
Some folks prefer metal zipper pulls. Others prefer cord pulls. So, what to do about that? We think the best solution (in most cases) is to offer metal pulls and include a starter pack of Cord Pulls with most bags. The most popular solution is to weave the Cord Pulls through the metal pulls, effectively silencing them without having to remove them. A video demonstrating various Cord Pull options and more colors/varieties of Cord Pulls can be found on the Cord Zipper Pulls page.
An adjustable and removable sternum and waist straps with leave-no-trace hardware: if you don't like or don't use your sternum strap, remove it and leave (almost) nothing behind.
Choosing an Exterior Fabric
You like choices and we like to give you choices! That's why the Paradigm is typically available* in three different exterior fabrics. Our Materials Glossary explains each fabric in great detail, but here are some quick facts that may help you decide which to choose. And we're always here if you have questions: email@example.com

- Made in:
Choose this fabric if
- You want a lighter weight alternative to traditional nylon fabrics that has remarkable tear strength and good abrasion resistance.
- You're looking for a fabric with a modern, "technical" appearance.

The bag's size fit me very well!
Not that big not so small.
The design very handy and useful.
When it loaded, it can stand by itself.
The only thing I think can be develop, is it better have a pocket in front of the main compartment, as the same as daylight backpack's pockets on the back, make more management.
But is can solve by another way.
I use a freudian slip of small cafe, it's fit perfect!
Love this bag! it's the third favorite bag of tom bihn I ever have!

I asked for this for Christmas to replace my handbag. I'm older and have a cranky shoulder. I hoped to wear it on my back thereby putting the weight evenly on both shoulders. As it turns out, I can't get it there w/o help. BUT it is just as useful as I thought it would be -- it keeps everything organized and easy to get to. I carry it w/my good arm OR wear it on my chest using both shoulders - depending on the day! As a geezer, I really don't care how I look as long as it works!!!

I needed a daypack to wear during travels that would not be too big so that I could not fill it enough stuff to make it too heavy to carry for hours on end. The Paradigm is perfect for that - I can fit in a few books, a jacket, umbrella, iPad and other travel essentials in this small PLO. The downside is that the front compartment is rather short - I found that nothing bigger than a Yeti 12oz bottle or Hydroflask 18oz bottle (fyi it will be a little harder to get the zips to pass the top of this bottle) will fit. But I'm ok with that, I can just fit my bottle into the main compartment. Lastly, I tried ordering this in both Ursa and Coyote Ballastic - the latter has a beautiful sheen to it that the Ursa lacks, and I noticed the Ursa picked up scuffs that were really visible (although could easily be wiped off). Just FYI as well if that bothers you.

I've been travelling exclusively with an Aeronaut 45 since 2015. I love that thing so much I bought one for my now-husband not long after we started dating. Over the years I've purchased so many Tom Bihn bags and gifts for friends/family/loved ones, and I finally decided to treat myself to a PLO. I have hypermobility spectrum disorder, so finding something that's functional and comfy is hard. It also doesn't help that I'm 5'2 so most proportionate bags are kiddo bags, which means that straps are of questionable quality and often awkward because...you know, they're not designed for an adult. This fits the bill on all accounts while making sure that there's plenty of space for all of the things I need for work (college prof. and grants coordinator), real-life (mom to a toddler and 2 dogs), plus play (three words: hands. free. adventuring.) If you're thinking about it like I was for the longest time...JUST ORDER IT! I swear it's 1000% worth it.

This bag is just the right size for me (I am petite) as one of my EDC bags. It looks durable and it has a pretty thoughtful storage and design for a small bag. I love the smaller outside pocket as it's spacious and has dividers to organize your stuff. The left pocket I use for small electronic edcs, the middle pocket I use for a water bottle or a small umbrella (it even has a small hole at the bottom to drain any leaks), and the right pocket I use for make-up or other hygiene items. The main pocket is also spacious and it can hold my 13-inch MacBook pro. Overall, it's perfect so far for my daily needs and I think, I'll be using this bag for a very long time.
