Description

People hike, travel, or commute with this versatile pack; where will you take it?

 

The Synapse 19 is a carefully calculated, supremely organized backpack, designed for day hiking, everyday carry, and ultralight travel. Its graceful, curvilinear exterior may on first blush 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.

The Synapse 19 is designed to fit people from approximately 5'0" to 6'0" / 1.52 to 1.83m; it's the smaller version of our Synapse 25 (for those 5'6" / 1.68 m or taller or who want a bigger bag — check it out). With 30% less volume, it's ideal for those of us who just don't need to carry as much stuff.

It features our beloved Edgeless Straps; conformity is overrated — except, perhaps, when it comes to shoulder straps. The edgelessness of this 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.

The front of the Synapse 19 is divided into five zippered pockets, all of which zip shut with #8 YKK® Raquet-Coil water-repellent zippers:

Though you'd never guess by looking at it, the top center front pocket is deep enough for a 1-liter water bottle or 1-liter hydration bladder. Everyone who has carried a water bottle in a backpack knows how important it is to pack the water bottle wisely so it a) doesn't dig into your back and b) doesn't throw off the weight of the pack. With the water bottle kept in dead center of the Synapse 19, you won't have to worry about either. Removing the water bottle from the Synapse 19 (and replacing it) is a breeze. Note that the water bottle pocket doesn't needlessly continue to the bottom of the bag; that'd be wasted space, plus you'd have to reach farther in to pull your water bottle out. Instead, we took that volume and allocated it to the bottom pocket (where it can serve good instead of evil — see below). Also worth noting: the water bottle pocket has one O-ring. (Yes, we do listen: we're adding O-rings. Just because you asked.)

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 lined inner organizational pocket; the left pocket has three pen/pencil slots. 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; two O-rings are inside this pocket. (Packing advice: tether one of the above-mentioned organizational cubes or Organizer Pouches to the O-rings via a Key Strap.)

The Synapse 19 has one main, back compartment for large, flat items like notebooks or laptops — it closes with a #8 YKK® Racquet-Coil water-repellent zipper. It has two O-rings for you to attach Organizer Pouches or tether other items. Also inside the main compartment are four unobtrusive webbing loops (also known as rail loops), two fore and two aft, to which you can secure the optional Cache (available in sizes specifically for every Apple laptop and iPad; PC users, click here to take a look at our Laptop Fit Guide). When you add the Cache, the Synapse 19 becomes a "checkpoint-friendly" laptop backpack. Here's how it works: on the sides of the Cache are two parallel "rails" of 1" wide lightweight nylon webbing which extend from the top to the bottom. Included with the Cache are two Gatekeeper Rail Clips: unclip the side that isn't clipped to the Cache, slip it through the webbing loops in the Synapse 19 main compartment, and flip it shut. Slip the Cache inside the Synapse 19, and pull it back out: you'll see that the Gatekeeper Rail Clips ride the rails of the Cache, allowing you to remove your laptop or tablet from the Synapse 19 entirely while it is still encased in the protective Cache. Many of us will appreciate this functionality on a daily basis: the rail system can be a convenient and quick way to remove one's laptop from the bag. And remember, there are four loops of webbing in the top of the main compartment of the Synapse 19: one pair is on the back side, and one pair is on the front side. That means you can choose to have your laptop or tablet against your back or against the front of the bag, whichever seems most comfortable or most convenient. Using all four loops, you could even carry two laptops (or one laptop and one tablet) in the Synapse 19. Note that the "checkpoint-friendly" functionality will only work for one of two devices — you'll need to remove the second laptop at the airport security checkpoint.

In addition to the Cache, the rail loops can also tether the optional Synapse 19 Internal Frame — you can even secure the frame and a Cache to the same set of rail loops. A clever “T” bar holds the loops in place relative to the frame, allowing the lower edge of the internal frame to float freely; in all of our testing, we’ve found this isn’t much of an issue as the bag’s contents tend to keep this lower extreme in place. The frame is constructed of die-cut .060” thick High Density Polyethylene (HDPE), with a nylon webbing sleeve sewn down the center that encases a removable 1” /25mm wide 6061 aluminum stay. We’ve bent the stay to a generic spinal curve but we recommend you re-bend and/or adjust the curvature to best fit your own back (video instruction here). Some folks swear by internal frames and others find them superfluous. For more on internal frames—how they differ from "frame sheets" and the pros and cons of using one—see our Guide To Backpack Frames.

Also inside the main compartment is an elastic-topped, open-top pocket. Generously sized to fit a book or two or an extra pair of shoes. The open-top pocket will also fit some sizes of Cache, including the 11" Air, iPad, and iPad mini sizes. (If you plan to carry a water bottle in the water bottle pocket and also an iPad or other device in the open-top main compartment pocket, make sure the device is protected with a Cache or a similar protective sleeve: the water bottle pocket is directly in front of the open-top pocket and your device is best protected from your hard water bottle.)

The remainder of the main compartment opens wide — ready to accept whatever larger items you're packing.

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. The contoured backpack straps of the Synapse were custom designed by Tom for maximum comfort. We tested the Synapse backpack straps on a wide range of people — all heights, shapes, and sizes — and we think we've come up with straps that work for just about anyone: no small feat!  The Synapse 19 features adjustable and removable sternum and waist straps with leave-no-trace hardware: if you don't like or don't use your waist or sternum strap, remove them and leave (almost) nothing behind (a design inspired by nature). At the top of the back of the pack, you'll find a webbing loop: use it to hoist the Synapse 19 up and onto your back or to hang it on a coat hook.

Enough said. Now get one and get out of here.

Great backpack

I just took this bag on a three week family vacation to Florida. I packed ponchos, a rain umbrella, sunscreen, snacks, multiple water bottles, etc. It got shoved into small lockers, stuffed at my feet on rides, rained on, and generally beat up and it held up beautifully! The organization was perfect. Great bag!

An Amazing Smaller Backpack

I just took my Synapse 19 on a trip to the Everglades and it performed really well. I love all the zippered pockets and was able to fit my binoculars in the upper middle pocket. I could easily fit my iPad and Kindle in the pack along with various stuff sacks and my Side Effect. The backpack fits me perfectly with very comfortable straps. I customized it with wasabi cord zipper pulls and it looks great.
