    Perfect Day Bag

    Never owned a TB bag but recently picked up a T30 and side effect in spectron and love them. They look sharp. The fit is comfortable and light. You can tell all the products and designed with function in mind. Never thought I’d become addicted to TB bags but now I want organization pieces to clip into my bags like the organizers and ghost whale. New fan of TB.

    Side Effect

    So far - so good. Just the right size for every day. The exterior color is a bit lighter than the picture on the website though…

    A great EDC

    I love this bag when I have to carry a small camera, my keys, my Kindle, and a few other accessories. Great quality and extremely functional.

    Fantastic bag

    Can use as small purse or hip bag. Fits more than you’d think!

    Perfect pouch for Pleasant Pursuits

    I have a couple of these that I throw in my brain bag for weekend travel. They are great for travel/portable games, cards, die. Or extra walking around items like handy wipes, first aid, et al.
