Thoughtful main compartment design: Perfect for storing large, flat items and includes a banded open-top pocket that is spacious enough for a pair of sandals.

Stay organized on the go: Five exterior pockets with room to spare — including one just for your 32 oz water bottle.

Pack it your way: Cache loops to attach a 16" laptop and additional O-rings for extra organization in the main compartment.

Breathable back panel: Provides maximum airflow while still being gentle on clothing.

Support when you need it: Edgeless shoulder straps that softly conform to your shoulders and adjust easily — featuring sewn-in strap keepers to keep things tidy.

Travel-friendly design: Webbing loop on exterior bottom that serves as an extra grab handle — can easily pull Synapse from under the seat or the overhead compartment.

    Great bag!

    The Synapse 25 is perfect for travel. It fits perfectly under a plane seat even when it's fully packed out. There are so many great compartments, truly an amazing bag.

    really great EDC!

    I love the amount of pockets, especially the small side pockets. A few areas for improvement: the part of the shoulder straps that connect to the bag seem a little thin; if you don't fill the bottom compartment, the bag doesn't really fill up its shape well; I wished that the inside of the bag was a bit less of a "black hole" and that there were more built-in compartments in the main compartment.

    Great Daypack

    This daypack is the best one I have ever owned. I love the outside pockets and it is a perfect size. If I had to make one recommendation it would be to have an indoor zipped pocket in the main compartment to store my wallet, keys and passport. I would never put these items in an outdoor pocket when traveling and I like to be able to get them out of the backpack quick and easy.

    Great! Spend the extra money and keep it forever!

    After looking at other brands I decided that I wanted the quality and durability of Tom Bihn bags . I’m 5’2” and I wanted a backpack to carry to work everyday and I don’t carry a laptop with me. I tried the Sinyk22 first and loved everything but the hard to pull with one hand main zipper, for a lot of people this wouldn’t be a problem and it would be the perfect bag. Then I tried the Synapse 19 but that was just too small. These first two bags were supposed to be best for a shorter person like me. I decided to order the Synapse 25 even though I was supposed to be better for taller people. I had seen people complain that this larger bag was floppy. I don’t think it is. At first I had a clipboard in the pack to work as a stabilizer but decided it wasn’t necessary. Of course it is extremely well made and I’ll have it forever. I’m not a one bag traveler but I would use this bag when I travel for my non clothing items. The pockets on the front are incredibly large once you open them. It is amazing how much you can fit in the bottom pocket. But the main thing I will never go without in a backpack is the center of the bag water bottle pocket on the front. No longer does my pack get lopsided or do I have to dig for my water bottle at the bottom of my bag. If it weren’t for the zipper issue I would have kept the Synik 22 though I wouldn’t pick it if I were carrying a bigger laptop. Other backpacks by other companies are just no where near as well thought out, efficient or durable.…
