She writes of the design and material:
"The Co-Pilot has one main zippered compartment with two interior pockets and one D-ring. It has three front compartments: two on either side (with various pockets) with a D-ring each and a water bottle/umbrella holder in the middle. There’s also a back pocket that can be zipped open so the bag can rest on rolling luggage. First and foremost, I have to comment on the Dyneema. I know everyone comments on this, and I have to as well. I can’t say that I know the ins and outs of Dyneema, because I don’t. What I do know is that, although the material is thinner than ballistic nylon or Cordura, it looks and feels quite strong. As others have mentioned, I appreciate how much give the bag has. Also, the construction of TB is top notch! The interior of my bag is Solar and it is probably the happiest color EVER! Seriously! And it makes finding things in the bag a cinch!"
"I have to comment that Tom Bihn changed the way I pack my EDC. I’m very careless and usually just squeeze things in together as long as they fit. But I love the convenience and organization the organizer pouches and the d-rings provide. It makes my life a whole lot easier. A place for everything and everything in its place."
