Full Description

Three Main Compartments

The Trinity has two main compartments of equal size and a slimmer middle compartment. The outer compartments can both open fully clamshell if you’re planning on packing for travel, or you can just unzip halfway if you’re using the Trinity for everyday carry – the zippers have enough resilience so you don’t have to worry about the clamshell compartments unzipping fully every time.

The front main compartment (when facing the TOM BIHN logo) has a stretch mesh inner vertical divider, which you can choose to leave zipped or unzipped. When zipped up, the divider splits the compartment into two equal sections, each with an O-ring over it. The two equal sections are large enough to pack any of our organizational bags. The divider also doubles up as a water bottle holder (remember the Luminary?). Situated in the center of the compartment, it is large enough for most 24oz and some 32oz water bottles. If you don’t plan on carrying a water bottle or want to keep the divider unzipped, note that the water bottle holder also packs flat, staying out of the way if you need it to.

The center main compartment is designed to store up to 16” laptops and is purposefully compact to prevent your device from shifting back and forth when you’re carrying the Trinity in any mode. It has two elasticized dividers running the width of the pocket, situated on each wall of the compartment – great for carrying files or separating out your devices into sections. The bottom dome has sewn-in foam to create a soft padding for your devices. The Trinity is designed in a way that allows the center compartment to compress when the front and main compartments are packed, thus creating more protection for devices.

The back main compartment opens fully clamshell and boasts two O-rings and a set of removable compression straps (similar to the ones included in the Western Flyer, Tri-Star, and Synik). Designed to pack like luggage, the compression straps will keep your clothes neat, flat, and compact.

Three Front Exterior Organizational Pockets

The front of the Trinity is designed with three large organizational pockets for your quick-access items. In briefcase or shoulder bag mode, the center front pocket is expansive, horizontally-oriented, and spans the height of the bag. It opens with a curved zipper, creating a wide opening for your quick access items, from a sweater to travel documents. Inside, there are two open-top pockets big enough to fit any phone or a Vertical Packing Cubelet, and two smaller pockets sized to fit pens or a stylus. At the top of the pocket are two O-rings for you to attach any optional pouches.

On each side of the center front pocket are two symmetrical pockets that open with vertically-oriented curved zippers. Two O-rings sit inside each of these pockets. While the pockets look equal in size from the outside, we purposefully designed them to be different. The left pocket is slightly larger and big enough to fit a large tablet, while the right pocket is just the right size for a 3D Organizer Cube or Side Effect.

Three Ways to Carry the Trinity

Backpack
Housed inside the back exterior pocket is a pair of fully removable backpack straps as well as a small loop made out of nylon webbing to hang the Trinity up backpack-style. The backpack straps are padded at the top to create a comfortable carry while unpadded at the bottom to make them easy to fold and stow. The unpadded ends of the backpack straps are attached to the bag with side-release clips, which are tucked into their own pockets behind the back panel, allowing them to be cleverly hidden if you don’t want to use the Trinity as a backpack. A pair of sewn-on strap keepers is included with the backpack straps, so you don’t have to worry about dangling ends. 

Shoulder Bag
The attachment points for the shoulder strap are located outside the center main compartment to provide the best balance and comfort. A Standard Shoulder Strap is included with the Trinity. If you anticipate carrying a very heavy load or if maximum comfort in shoulder bag mode is your priority, we recommend upgrading to the Absolute Shoulder Strap.

Briefcase
Two comfortable, padded grab handles made from PORON® foam sit directly above the center of gravity for maximum comfort, stability, and balance. The handles “kiss” at the top, allowing them to be easily held in one hand whether you’re on the go at the airport or just commuting day-to-day.
 

Rolling Luggage Handle Pass-Through

For minimalist travel, we think the Trinity can easily be sufficient for up to a 3-day trip as a standalone travel bag. But if you prefer using a rolling suitcase as well, then the Trinity is well-suited to be a personal item carry-on to pair with your luggage. The built-in pass-through slot fits over the handles of most standard rolling luggage (up to 8” or 20cm wide). Glide it over the handles and have easy access to all your main compartment zippers from the top of the briefcase. 

Additional Grab Handles

In addition to the two PORON® grab handles, a grab handle made out of silky webbing sits on either exterior side of the center main compartment to help facilitate grabbing your bag from under the seat or the overhead bin no matter which orientation you put it in.

What's Included

One Standard Shoulder Strap
1.5" / 38 mm nylon webbing strap, includes .25" / 6mm texturized rubber pad and heavy-duty plastic snaphooks. 

One 8" Snaphook/Snaphook Key Strap
As with most of our bags, we've included a key strap. 8" long from tip-to-tip, a snaphook on either end. Good for attaching your keys to.

A Set of Black Zipper Pulls
A set of pulls to extend or replace your metal pulls.

One pair of Tie-Down Straps
Our included tie-down straps are an alternative to packing cubes: use them to compress and secure clothing in place to help keep it wrinkle-free. They're removable so if you don't want or need to use them, you can leave them behind. 

What's Optional

Absolute Shoulder Strap
Upgrade from the included Standard strap to an Absolute Shoulder Strap if you anticipate carrying a heavy load.

Packing Cube Shoulder Bag
We recommend storing your clothes or shoes in a Packing Cube Shoulder Bag and use the included tie-down straps to compress your load.

Cache
The Trinity can accommodate a wide range of laptops and tablets. While the bag has sufficient padding, we recommend using a Cache for extra protection.

Organizer Cubes
Clear 3D Organizer Cubes, All-Fabric 3D Organizer Cubes, and Vertical Packing Cubelet: perfectly sized for rounding up cables and doodads and storing in the front organizing pockets.

    The best bag I've ever owned

    The perfect size for flight travel, especially if you're flying on smaller jets with limited stowage space. The placement of the compartments makes for easy access to multiple high-touch items quickly and frequently. Beyond its utility, it's also strikingly beautiful, the best-looking of all the Tom Bihn bags I've come across. The only thing I wish were different is that I would have loved to have more penholders in the front compartment. Other than that, it's perfect.

    Better than god

    Blasphemous I know, but this Trinity is the best 3-1 in this category. I normally don't like bags that try to do too much but this bag does all 3 well while still staying true to the Tom Bihn style.

    Great work bag!

    I upgraded to this bag from a Cadet briefcase, primarily so I can use it as a backpack OR shoulder bag. It does both beautifully.

    Great for daily and 2 day trip

    I like the organization and possibility to use backpack configuration

    It’s my new main daily bag for work, and also use for 1 night work trips

    Will be great to supplement with roll around carry on for longer travels

    Could be 5 stars but the price is pretty steep in comparison to other offerings (including Tom Bihn) - I don’t really see many people justifying to spend the money on this but I could be wrong

    Perfect for working during air travel

    Recently I chose to take my Trinity on a business trip, instead of taking my Brain Bag or Synik 30 or Paramour. I had to take my 16” Macbook Pro, my 13” personal Macbook Air, and my 8.3” iPad Mini. The Trinity was the perfect choice for easily and quickly getting and putting computer, tablets, and papers, thanks to the horizontal, briefcase orientation, and the multiple pockets that each can hold up to a 16” laptop computer. That easy access is especially important with the tiny legroom of Economy seats. I did not need to contort myself to deal with backpack pockets. That easy access also was welcome when suddenly came my turn to get up from my gate waiting area seat.

    There are many other situations, not during air travel, where rapid and easy access to computers makes briefly using them worth the effort. Of course, all briefcases have such easy access. What makes the Trinity so much more useful than a briefcase is its triviallyeasy transformation into a backpack, for other situations whhich for me even during business trips is the majority.

    I still use my bags that are primarily backpacks (Synik 30, Synik 22, Paramour) in most situations, because their shoulder straps are more comfortable, they are better when rapid computer access is not so important, and for bulkier items.
