  • Front pocket with O-ring for keys, a wallet, or a small camera
  • Left pocket with pen/pencil slot and 2 wide slots
  • Right pocket with small organizational pocket
  • Bottom front pocket for extra clothing or snacks
  • 1.5"/38 mm webbing loop on exterior bottom of bag to hook on a small flashlight
  • Flexible main compartment for laptop/tablet (check fit guide) with 4 unobtrusive webbing loops on the inside for attaching optional Cache (no integrated laptop sleeve) or Size 1 Handy Little Thing
  • 2 O-rings inside the main compartment for additional organizational pouches, if needed
  • Meets the personal item requirement on most airlines

If you love the design of the Synapse 19, but want a bigger version, check out the Synapse 25.

Full Description

The graceful, curvilinear exterior of the Synapse 19 may at first look like something akin to sculpture, but in truth it is simply the judicious realization of ultimate utility. No mesh pockets clutter the exterior of this bag, nor extraneous straps festoon it; in it, you'll be able to carry more than you would imagine, and no one will be the wiser.

Five Front Exterior Organizational Pockets

All five pockets are zipped shut with #8 YKK® Racquet-Coil water-repellent zippers:

The top center pocket is deep enough to fit a 1L water bottle or hydration bladder. Removing the water bottle is super easy since the pocket doesn't continue to the bottom of the bag. By having a heavier object in the middle, the carrying experience is more comfortable since everything becomes balanced.

Below the opening for the bottle pocket is another small zippered pocket, also with one O-ring; it's just deep enough for keys, a wallet, glove liners, or a small camera.

The side pockets are generously sized for sunglasses (in a case or alone), a first aid kit, or even a light Windbreaker-type jacket or down vest compressed in a stuff sack (like our Travel Stuff Sack). The right side pocket has a small organizational pocket; the left pocket has one pen/pencil slot and two wider slots for multitools/knives or just more pens. Both side zippered pockets feature one O-ring — one comes with an 8"/200 mm Key Strap.

The bottom front pocket of the Synapse 19 is a great spot for extra clothing or snacks and will easily accommodate a thin wool/fleece sweater, light down jacket and/or Windbreaker-type jacket. If you care to add organization, it's more than big enough for a 3D Organizer Cube or Side Effect. And because we care about your safety, we've added a 1.5"/38 mm webbing loop on the exterior bottom of this pocket that's ready to accept a flashlight — highly recommended if you ride a bicycle or walk in the dark.

Main Compartment

The main compartment is designed to fit large, flat items like notebooks or laptops — it closes with a #10 YKK® Racquet-Coil zipper. It has two O-rings for you to attach Organizer Pouches or Key Straps or tether other items. Four unobtrusive webbing loops can also secure the Cache. The remaining space in the main compartment opens wide.

Interior Banded Open-Top Pocket

Also inside the main compartment is an elastic-topped, open-top pocket. It's suitable for storing a few books, an extra pair of shoes, a Size 2 Handy Little Thing, or a Tri-Star Medium Packing Cube. Some sizes of the Cache will also fit inside this pocket.

Breathable Back Panel

The back panel of the Synapse 19 is padded with 1/4", high quality, closed cell-foam with an exterior of Spacer mesh and 210 denier nylon. This combination of mesh and smooth nylon is designed to provide maximum breathability while still being gentle on your clothing.

Included Removable Sternum Strap + Waist Strap

As with all of our major backpacks, we include adjustable and removable sternum and waist straps: if you don't like or don't use your waist or sternum strap, remove them and leave (almost) nothing behind. There's also an optional 1" Padded Hip Belt.

Edgeless Straps

Conformity is overrated — except, perhaps, when it comes to shoulder straps. The edgelessness of this new strap allows it to more softly conform to your shoulder — we (and most people who have worn these straps) find that this increases comfort. Yet the straps aren't too soft: the 1/2" thick EVAZOTE® OEKO-TEX® certified foam means the strap is robust enough to carry a heavy load.

Durable Materials + Expert Construction

No bag lasts forever, but choosing the best and most durable materials and taking care not to abuse it (no washing machine or dryer!) can help a quality bag serve most people well (with maybe a repair or two) for up to 10-20 years.

For the interior lining of the Synapse 19, we offer variations in 200d Halcyon or 210d Cerylon, both ultra-lightweight and ultra-tough. They have been abrasion tested by both our fabric suppliers and our in-house lab. Conclusion? 200d Halcyon and 210d Cerylon are perhaps a bit overkill for a lining fabric, and you expect nothing less from us.

This bag requires significant skill to sew and construct; it's not just any sewing factory who can pull this off and do it well, it's ours, and it's because of the talent of our crew. They're the reason why our designs can be made in an ongoing practical fashion.

Fits pretty much anything I need to carry

I purchased this as an daily carry bag now that I've headed back to the office. It fits everything I need for my day - laptop, insulated water bottle and all the small, random stuff (mask, hand sanitizer, wallet, etc) fits in the outside pockets. If I'm going on a hike, I swap my laptop for a 2L hydration pack, which is inside an insulated bag and clipped to the O-rings in the main pocket.

I'm short (barely 5'2") and have a bad back, and this backpack fits perfectly and is so comfortable to carry, even loaded up. I did upgrade to the padded waist belt for the days I need to carry a heavier load, which I haven't had to use yet, but I can tell it will definitely help.

Even better than the original!

I've had a classic Synapse 19 since Summer of 2017 and it had the original straps, handle, zippers etc. While I love that bag to death and it holds a special place in my heart forever, I am thrilled with the small updates that have been made! I got a new black Synapse 19 in ballistic with the blue island interior. The zippers feel SOOO much smoother and easier to open/close than my older bag. And the new straps are very soft, which is nice when wearing a tank top. Couldn't reccomend this bag enough :) Will be keeping my old one for hikes now to keep the black clean for work/travel.

One Bag to Rule Them All

The TB Synik 22 was my first quality backpack. I cherished it, but quickly went on the hunt for a perfect pack and sold the Synik. I tried Evergoods, GoRuck, and more. I found myself back where this obsession started. There isn’t a perfect bag out there, but the Synapse (or the Synik if you only use thin, small laptops) is as close to perfect as it gets.

It is comfortable on your back with luxurious shoulder straps. The organization is spot on and allows you to access only what you need at any given moment. The lower weight of the Synapse coupled with the lack of laptop slot make the Synapse more versatile for me, but you cannot go wrong with either style.

Such a Happy Bag!

I swore off backpacks once, but then I missed having this perfect size bag for days when I had extra "stuff." Then came this Deep Blue/Zest colorway, and I knew resistance was futile. It makes me smile every time I look at it, especially packed out with Zest accessories. Of course, it's the same great TB quality as ever, and I can always count on exceptional customer service. What's not to love? And why would I want to resist??

Perfectly Modular EDC Pack

Wow, okay. Where to begin... finding the perfect pack to handle various carry duties has been tricky, until I found TB & the S19. After a few weeks of shuffling my gear around to different pockets I think I have what amounts to be the best layout and size for an EDC pack. Included is a generous IFAK, 14" laptop with cache, folding knife, flashlight, hand sanitizer, 1L collapsable water bottle, mints, gum, chapstick, a Cubelet for charging needs, and a HLT1 for all the tech accessories that anyone would ever need. All this stuff is easy to find and reliably in the same spot at all times. And if I want to take a hike and bring along a small camera kit pouch, I leave the Cache, Cubelet, & HLT1 and swap a Side Effect in its place. There's ample room to spare for a lightweight merino hoodie and an extra t-shirt or two. Also love the o-rings with key straps to keep accessories tethered so no Bihn left behind whether you're out on the town, in the woods, or just passing time while you have a car service appointment. If you love modularity, organization, and build quality like no other, just stop reading and get this thing. It's that good.
