All About O-Rings

O-Ring-Organization | TOM BIHN

If you already have one of our bags, you probably know about (and perhaps love) our O-rings.

If you’re new to our bags, you may be wondering — what’s all this about O-rings? They are just as they sound: small, round, plastic rings sewn inside many of the compartments and pockets of our bags.

Cool things you can do with O-rings:

Any of our Organizer Pouches can be clipped to O-rings to add further organization.

Clip an extra Key Strap or Utility Strap to an O-ring to keep track of an extra set of keys, your work/school ID, pocket watch, or Swiss Army knife.

The Guardian Dual Function Light, a dual-function safety light, can also be clipped to an O-ring and used to illuminate the interior of your bag.

Clip a 3D Clear Organizer Cube to an O-ring via a Key Strap, and you have a TSA 3-1-1 liquids bag on a tether — ensuring you won’t lose the Cube when going through the airport security line.

    Not helpful. Is there a guide to all the o-rings on each bag, and what they were designed to enable?

      There’s a count of how many o-rings each large bag has in the Specs section on product pages! We don’t recommend specific accessories for specific O-rings because there’s so many different Key Straps and Organizer Pouches options that could work with each O-ring: customizing the use of each O-ring depending on what one carries is part of the fun 🙂 We are, however, working on a video all about O-rings that demonstrates how various folks use them. Inspiration for that video came from this thread on our Forums, and you might also find some inspiration for O-ring organization there:

      Hope this helps a little bit!

    There should be a warning on your product pages about how addictive O Rings can become! 🙂

    Seriously, they’ve had such a positive impact on how I pack my EDC and travel bags that when I use a bag other than a Tom Bihn, I get frustrated that there are no O Rings.

    In my EDC pack (either a Stowaway or Pilot) I have my first aid kit, my WiFi hotspot, my flashlight, a set of keys, a mini toiletries kit (toothbrush, floss, toothpaste in a clear TB pouch), and a 3D organizer pouch all attached to O Rings. When I move from one bag to another, or into my Tri Star, Synapse 25 or Daylight, it’s a snap to move them and I don’t worry about forgetting items that I’ve pulled from the pack.

    Anyway, I’m “hooked” on O Rings. (Yeah, that was a predictable pun.)

      Ha! Hooked on O-rings — how did we not think of that before?!

      Tom and Nik are in the process of reviewing existing Organizer Pouch and Key Strap offerings — and designing new ones. Anything in particular you’d like to see, Thomas?
