I purchased this bag to use as my personal item on flights. It not only holds everything I need, but it is super comfortable to wear and fits under the airplane seat perfectly. I’ve definitely caught the Tom Bihn fever!

I love this Synapse 25! It holds everything and is well organized. I just wish I had gone with my gut and bought the 19 instead, as the 25 is huge!! Guess I’ll start saving up for another bag!

As an owner of a Halcyon and Ballistic fabric packs, I’ve been looking forward to the Synapse 25 showing up in the new Spectron material. When it finally arrived on the store, it was an easy order for me. Received the bag and it’s nice and light as expected. Love the TB external tag in the subdued black/grey color and the subtle sheen of the new Spectron. The rest of the bags layout is easily familiar. The straps are comfy and not slick and the light colored interior is easy to spot stored items against. The bags overall fit is comfy and makes a wonderful EDC pack. Looking forward to many years of use from this new bag. First 2 photos are under inside light while the last photo is outdoors lighting as I wanted to see how shiny fabric could be in direct sunlight.
