Description

The Parental Unit is the result of our determination to build a bag that does more than just help with diaper changes—it’s designed to keep parents organized, mobile, and ready for whatever the day throws their way. Whether you're heading to the store, the in-laws’ house, daycare, or even the museum, the P.U. makes every outing smoother (and maybe even enjoyable). And because we believe style and practicality can coexist, we skipped the cutesy prints—this is a bag that looks good on everyone. No oversized, unwieldy monstrosity here—just a sleek, thoughtfully designed carry that won’t whack strangers in the face as you navigate a crowded subway or cozy café.

    Hope this comes back into production cycle

    This bag has now become my every day carry. All the pockets help you organize the things you use a lot into easily accessible sections, and relegate rarely-used-but-needed items out of the way. Since I have items categorized and sorted away into the pockets, it leaves the main compartment clear and empty, ready to have things stuffed into it for toting. I use an Absolute Strap with it—since for me it has a "front" and a "back"—and it is comfortable even when I load the bag up (I do wish I could shorten the strap up a little bit more since the shape of corners of the bag adds some length). I especially like the outside clip on the back of the bag—the perfect place to clip your keys so you don't lose them at the bottom of the bag. My bag is Taiga halcyon with the dark crossthreads, which I find is a great neutral. I have gotten lots of compliments on this bag when I'm out and about!

    The Parental Unit is my favorite bag ever

    I use the parental unit as an everyday carry. It is durable, comfortable to wear crossbody, and full of a ton of helpful pockets to keep me organized. I love bags and this is my favorite everyday carry ever. Please keep making them, Tom Bihn!

    Long lasting

    I have owned the Parental Unit for ten years and use it five or six days a week for work. I walk a mile to work, a mile home. Now, it doesn’t look as good as the day I got it in the mail, but it has mostly held its shape and shows minimal signs of wear. So 5 days a week times 52 weeks a year times 10 years, that’s 2600 days I put this bag to the test. As many times as I considered buying a new work bag, there’s just nothing out there as seemingly indestructible as this, with all the pockets I could ever need. This bag will outlast me, I’m afraid.
