Our Thoughts

Tom Bihn is a legendary carry-on maker so you know this bag is well made and has all the features you'll need.

Going with an established bag maker is always a great choice. A person named Tom Bihn started Tom Bihn over 40 years ago. 40 years of experience means this bag will hold up vs. the competitors. New carry-ons on Kickstarter won't have the same level of execution vs. an older company.

The Tom Bihn Synapse is one of the smaller one bags but still is enough for a 3-4 day trip. If you are flying on a more generous airline, consider the Synapse 25 for a little more space. 19L of capacity means you are fairly limited as to what you can pack.

πŸ‘ Reasons to Buy

  • Made from truly durable materials.
  • Minimalist design.
  • There are several add-ons available for this bag which makes it customizable according to your needs.

πŸ€” Things to Consider

  • Can pack less things considering it's volume is at 19 liters.
  • The placement of the water bottle pocket in the middle of the pack seems weird and inconvenient.

πŸ’¬ Reviewers Have Said

  • "After going through about 8 different bags over the years, I finally found one that works."
  • "The 19 liters is just the right size for everything I need and then the stuff my kids want to add in for a trip or a run to the park. It is the most comfortable backpack I have owned. From the padded back to the shoulder straps, everything feels balanced just right when it is loaded up."
