    Perfect everyday bag!

    Great size for a small purse or everyday bag. Well thought-out organizational pockets. Light weight with a comfortable strap that's easily adjustable and doesn't tangle or slip. It's also a perfect in-flight bag to hang from the airplane seatback (demonstrated in the first photo below, using TB swivel carabiners). A really versatile bag that holds more than it appears. One of my most-used and favorite TB bags!

    Shown below:

    The perfect hand bag

    I bought my first Side Effect in my very first TB order about 8 years ago. It has been my hand bag ever since. It holds key, wallet, phone, driving licence, tissues, lipstick, small change, sanitizer, and it's not even full. When black halcyon came out i bought another one, as i found halcyon can fit even more, and it's also lighter, and i prefer the look. I love also that the side effect fits in the bottom pocket of the Synapse 25 or in a side pocket of my aeronaut 30 when i'm flying with one-bag policy only. In black halcyon it fits with every outfit i wear. I also bought later on a side kick to see if it would be a better hand bag - but far too big for me :) if you are a minimalist lady like me (at least when it comes to hand bag content) you will love it! I recommend 100%

    Awesome "kit" bag

    I bought this to store a portable heating pad and accompanying accessories and it happens to be the perfect size for everything. I'm a huge sucker for the O -rings inside, and as with any bag I've had from these guys, the storage compartments just make sense. Far too often those small compartments just get in the way but with these bags you truly are getting the most legit bag experience possible. Treat yo self. And hey Tom and Friends! I really dig the saturated colors like alphaviolet and Viridian and would love to see more of that in the future. I also really love the Moab Halcyon, its under represented in the organizer bag category!

    All in all, my favorite thing about the bag is knowing that the people who made it get breaks and seem to be treated pretty damn well. I'm definitely not made of money but bags are something you want to buy nice, not twice. And while these are at the higher end of whats in my range, they seem to be worth every penny and the company from what I can tell has a business model that others should learn a lesson from.

    *If anyone happens to be wondering, it is slightly too small for a Nintendo Switch!

    Almost Perfect

    The size of this bag is perfect for daily carry for an average day. The materials are quality and the organizational pockets on the interior are clutch. I do wish however that there were pockets inside of the front zip compartment. I like being able to add in some easy access items to the front of bags but like to keep them stored separately so I can differentiate things like keys and medicine easily. Also would love it if there were a pen/pencil pocket in the main compartment. I love that it can be worn multiple ways as well! But I do find the waist strap is too short to wear my bag across the chest which is disappointing but typical as I have a larger bust (~48 inches) but it fits perfectly as a waist bag and crossbody purse.

    Perfect- inside other bags, or as it's own thing!

    I currently use a cubelet + super mini ghost whale + Nik's wallet inside a side effect as an every day purse like object carried cross body. I can carry my Pixel 6 phone, kindle paperwhite, headphones, sanitizer, extra K-95 mask, and keys. When I went to a recent work conference, it was easy to slip off the straps, and stash my side effect inside an icon. I could also take out the cubelet and carry it with a wrist strap. I am excited to use the side effect during the school year inside a teacher bag/backpack in this fashion, so that I can just take it out and put the strap on for the weekend/after school.
