    Trinity
    Rated 4 out of 5 stars
    It's great, but it's spendy

    I figured it was time to upgrade from my Maker's Bag, and the Trinity was finally here....

    I will say this, it has brought more order to my life that I ever expected. Everything has a place -- and my laptop is neither loose nor protected by stiff padding that made it hard to carry as an everyday messenger. I think they pulled it off. As a "personal item" carry-on it is perfect under the seat; it makes my endless in-flight juggling of devices and cables and batteries and snacks quick and efficient.

    It is very expensive, though, compared to other options. Arguably, it's a bag that doesn't need all the extra bibs and bobs you need to get a Maker's Bag to be a reasonable analogue, but even a fully kitted out Maker's Bag with organizers and cubes and pouches is much cheaper. For me, it was worth it, but definitely something to consider before you pay the money for it.

    Also, don't expect it to be a great backpack. I've used "convertible" packs in the past, and they all are mediocre backpacks at best. I'm disappointed they didn't put more into the pack straps (more padding, more stability), but for me the straps are an "in a pinch" form factor (like needing your hands free). If you're buying this primarily for the backpack form factor, be aware.

    On the whole, I'd 100% buy it again and you can pry it from my cold, dead fingers. But ask yourself if you need this much structure and ease of use. This is the best structured Tom Bihn bag, but I got a lot of life out of my Maker's Bag…

    Fantastic one-bag for short business trips

    1-3 nights of work on the road? This is my go-to bag. Just enough room for a couple of outfits and my travel tech. Great organization/pockets. It’s pricey, but worth every cent.

    The backpack straps don’t work for me (I’m 6’6, and they cut into me and are pretty uncomfortable), but I prefer it with the absolute shoulder strap anyway.

    waiting for this bag to be made

    I really love my Trinity. I have using a backpack for a while for work commuting on bike, but prefer a shoulder bag for use at work (I work doing advocacy for a nonprofit working on global hunger and I lobby Capitol Hill. I also always seek to support LOCAL handmade whenever and companies that treat workers well, whenever possible, from my coffee to clothing. Thanks for making a great product and a bonus to read the spotlight stories of your staff and dedication to their craft.

    I'm obsessed

    I love my Tom Bihn Synapse 25, but I decided to treat myself to a second bag because I was sick of converting my Synapse between day hike use and travel use. The Trinity is now my go-to travel bag where I can leave things like my travel swag and TSA bags so that they're always already packed for new trips. This tiny little bag holds so much! I'm a notorious over-packer but just did an entire Las Vegas weekend with ONLY this bag! I didn't even need my roller bag. The best part is how easy it can go from strapped to the top of my roller to a book bag to a shoulder strap bag. I'll swap back and forth constantly based on what drink I need to carry or things I need to hold for my boyfriend. I show it off to everyone, and I get so many comments about how cool it is. I love this bag!
