Description

True versatility: use as an organizer pouch, cross-body bag, or waist pack.

The Side Effect is a bag that has evolved directly from user feedback (mostly from folks on our Forums). The original Side Effect was a small waist pack: you guys were cutting off the waist straps, attaching Key Straps, and envisioning new ways to use the bag which we hadn't. Other mods — more O-rings, different label placement, a removable waist belt — were not DIY-able for you all. We decided it was time to catch up, and then some.

Think of the Side Effect as a deluxe, tricked out, fully organizable 3D Organizer Cube. The main compartment zips with two sliders; inside the main compartment are four O-rings -- two set dead center and two set in lower inside the bag in the side panels. There's also two open-top organizer pockets sized for your phone, a small notebook, or a wallet. The open space in the main compartment can fit larger items: 8-oz water bottle, sunglasses, snacks, souvenirs.

On the outside of the bag is a zippered pocket sized specifically for a passport (or multiple passports — in case you're carrying your kid's passport or you are Jason Bourne). That pocket spans the full width of the Side Effect; there's one O-ring inside it and clipped to that O-ring is an included 8" Key Strap in Black. The other side is clean: a solid panel of fabric. You choose which side of the Side Effect is the "front" and which side is the "back" by how you wear it.

Four ways to carry the Side Effect:

Included 5/8" Shoulder Strap
On either side of the Side Effect are O-rings to which you can attach the included 5/8" Shoulder Strap — nylon webbing, adjustable, with plastic snaphooks (no pad). Wear it over your shoulder or cross body, or use the 5/8" Shoulder Strap to hang the Side Effect on a coat hook or doorknob.

Optional Waist Strap
Also on the sides of the bag: unobtrusive webbing loops to which you can attach the optional 1" Waist Strap with our now-ubiquitous Gatekeepers. Attach the optional Waist Strap, buckle the bag around your waist or hips, and you've got a sweet waist pack — great for cycling, hiking, or any situation where you need your hands completely free.

Optional Handle Loop
Clip the Handle Loop to one of the O-rings on either side of the Side Effect and carry the whole affair in hand. Laden with heavy objects and swung correctly, the Side Effect becomes a weapon, but we would never suggest this use.

Key Strap
Clip one side of any variety of Key Strap to the Side Effect and then clip the other side of the Key Strap to an O-ring inside one of our larger bags. That way, the Side Effect stays tethered to your bag: convenient and secure. (Hint: the Side Effect fits in most of our bags, but we think it works especially well in the bottom pocket of the Synapse 25, side pocket of the Smart Alec, main compartments of the Small and Medium Cafe Bags, and clipped to the hidden O-rings in the Swift.)

Sewn in Seattle

Our bags are designed and sewn right here in Seattle, Washington, U.S.A.

That allows us to be control freaks in the best way possible; we have direct control and oversight of the quality of our materials, our products, and the jobs and working environment that we help create. It also offers us a unique spontaneity: when we have an idea for a new product or accessory, we can design it, figure out how to build it, add it to our website and be ready to ship it out our front door all within just a few weeks. How cool is that?

Intrigued? You can find out more about the unusual way we do business on our Company Philosophy page.

THE BIHN Guarantee

Everything you buy from us here at TOM BIHN is satisfaction guaranteed. We’ve been in business for over 30 years and we stand behind what we make.

Excellent “Fanny” Pack

I use the word “superb” a lot when I describe Tom Bihn gear. And I’m going to use it again. The Side Effect is a superb jack-of-all trades EDC fanny pack/shoulder-sling/cross-body carry bag. I have more fanny packs in my luggage collection than I would like to admit. And it’s not like there is anything really wrong with them. After all, a fanny pack is not exactly rocket science: attach a storage compartment to a belt that goes around your waist. That’s pretty much it. So, why do they all seem so unsatisfactory? Part of it, for me anyway, is that my use case seems to change with every trip. Photography? Little Leica? Big Sony? The Hassy? Quick trip with no camera but the iPhone? It all depends on what I want to do. But if I don’t need to carry around any glass of any particular size, the Side Effect has become my perfect go-to cross-body pack, replacing various iterations from Peak Design, Moment, Red Oxx (my second fave), and a bunch of Amazon stuff destined for Goodwill. I am about to set out on an 8-day trip with nothing but the Western Flyer and the Side Effect. The Side Effect holds my iPad mini 6 in its folio cover, a Merino buff, my folding RayBans in a hard case, my AirPods Pro, Field Notes notebook and Lamy pen, a tiny stand for the iPad, a Belkin 10,000 mAh battery with integrated cables, face mask, and room for a snack and Tom Bihn minimalist wallet.

The bag has modest organization capabilities: two small interior no-zipper pockets, which are perfect for things…

Favorite small EDC

I purchased this bag 2 years ago as my alternate EDC (I use a Medium Cafe Bag on my work days since I carry an iPad those days). I love this little bag for holding just what I need - wallet, keys, phone, hand sanitizer, LastTissue, extra mask, sunglasses; there's still enough room for little odds and ends while I'm out. The black version is so versatile that I have never felt like the bag was too casual for nice dinners out, nor too fancy/delicate for physical outdoor activities. This bag also works great for traveling, and went with me on several transnational and international trips before the pandemic hit. I keep transit tickets and other things I need to quickly access in the front zipper pouch. I love that both compartments have zippers to keep everything more secure while traveling. It's so easy to switch up how to carry it depending on the day's needs - I generally wear it as a shoulder bag but on days where I'd be hiking/kayaking/etc on my trips would switch up with the waist strap for a more secure way to carry it. When I first got it I was thinking about getting a second one "for backup" but this thing still looks new after all I've put it through in the last couple years I don't know if/when I would need to replace it :)

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%

A perfect small multitasker

My Side Effect has so many uses. Shoulder bag, cross body bag, waist/sling bag, clutch, cosmetic bag for travel, and an organizer in a larger tote. It holds so much more than you would expect and I love it so much, I bought an extra to keep as a backup.

As perfect a daily multi-functional travel companion as I've found

I travel often for work. I sometimes forget items in the airplane/train seat-back pocket or, when fortunate, in the first/business class nooks. Not so with inspiration from here: https://forums.tombihn.com/photos-videos-and-reviews/6614-side-effect-s-biners-seat-pocket-bag.html?highlight=side+effect+airplane.

My Side Effect (SE) holds my case-ensconced iPad Mini (snugly), notebook & pen & pencil & eraser (in an organizer bag), snacks, eye mask, flashlight, charger & cable & headphones (attached with another organizer bag). The organizer bags are key strapped into my SE, I clip the it to the seat back (even in 1st/BC), and enjoy easy access to my stuff without said stuff spilling (or, worse yet, spilling & rolling away). Flight attendants seem to like how I use my SE, have never asked me to remove it from the seat back before takeoff or landing, and it stays out of the way just enough where I don't have to remove it to let my row-mates pass to get to the lav.

I put a Gatekeeper strap on to turn my SE into a waist pack. Without straps it can tuck into a large coat pocket and can be clipped on the exterior of other bags (my Smart Alec, for example). For work, it attaches to my Pilot's interior as an organizer pouch.

I also sometimes use my SE as a small packing cube by turning it inside out: I use a key strap to clip it into my main bag, like I do with my other packing cubes, as flipping it inside out exposes the 4 O-ring anchor points.
