Badass BKPK

Badass is badass… simple. At almost 2000 cubic inches / 33 liters of capacity, you are good to go anywhere you want to, any time you want to. 

Panel loading design, large main compartment, middle organizer compartment for your EDC items, and lower garage compartment in the front offer enough carrying capacity and compartments to keep you rolling for days. A top loading, fleece lined hammock pocket, perfect size for your goggles, glasses, headphones and mobile electronics, all in a nice cozy hanging pocket that keeps ’em safe for easy access to the things you need quick. Additionally a back panel side entry pocket large enough to accommodate most lap tops up to 17”, and other stuff you want to keep stashed, out of sight and noticeable access. This side pocket also offers quick access for moving your laptops through airport security and doubles as a hydration bladder sleeve.

One of the reasons the Badass is so badass is in the carry design itself. Integr8iss (Integrated Shoulder Strap System) - A single integrated back panel and shoulder strap design and construction provides uncompromised fit, stability, and strength. There is NO shoulder strap sewn into a seam, or webbing cross-section, virtually eliminating any possibility of shoulder strap failure FOREVER. Did I mention unparalleled stability that also eliminates the need for a waist harness system? (which normally go unused 99% of the time anyway in packs of this nature). 

Also, as with almost all Firesign Brand equipment, this bag is equipped with Monkey Shackles. Monkey Shackles are our own zip puller /lock system designed to keep sticky fingers and otherwise unsavory peeps (or animals) out of your junk. Especially in tight, crowded spaces like subways, concerts, and campuses where it’s too easy to have stuff “pinched” out of your bag while making your way through the jungle. Monkey Shackles are also TSA compliant, and silent so if you’re trying to be discrete, no problem. What you probably didn’t know, however, is that Monkey Shackle zipper pullers are made of UHMWPE (Ultra High Molecular Weight Polyethylene) and are highly cut resistant and when removed and used as a link, can hold 650Lbs or 300KG’s of weight (tested to 1100Lbs ). So if you ever need to secure something, or hell, tow your boat, we have a solution in every bag.

Monkey Shackle Challenge: we want to hear about all the amazing ways your Monkey Shackle saves the day and every 6 months we are going to give one lucky winner something very special!

MOLLE webbing on the front and side panels allow for accessorizing your bags with a large array of secure, modular accessories. Also the YouLock loop at the bottom center is the perfect solution to stow your U-Lock when it’s not guarding your ride.

The Integrated Shoulder Strap System (INTEGR8iss) is a design feature found on the Badass Pack and while it may look ordinary, it’s far from it. A single integrated back panel and shoulder strap engineering and construction provides uncompromised fit, function, and strength. There is NO shoulder strap sewn into a side seam or webbing cross section, virtually eliminating any possibility of shoulder strap failure EVER.


Look for the YouLock loop at the bottom center. It is the perfect solution to stow your U-Lock when it’s not guarding your steed.


MOLLE is an acronym for Modular Lightweight Load-Carrying Equipment. It is used to define the current generation of load-bearing equipment and backpacks utilized by a number of NATO armed forces, especially the British Army and the United States Army. The system's modularity is derived from the use of PALS webbing as rows of heavy-duty nylon stitched onto the bag to allow for the attachment of various MOLLE-compatible pouches and accessories. This method of attachment has become a de factoem> standard for modular tactical gear, replacing the ALICE system used in the earliest modular vest systems (which is still in use with many police forces).
The MOLLE system was introduced in 1997. However, it did not see widespread issue until after the September 11, 2001, attacks and was used by U.S. troops serving in Afghanistan and, later, Iraq.

I purchased this backpack over 6 months ago and I must say it's one of the best backpacks (If not the best backpack) I have ever owned. From the organizational design, to the high grade fabric & materials used down to the craftsmanship. It's all top notch. This is what made in USA quality should be measured by. True craftsmanship. Anyone in the market for a backpack should definitely pick up a Firesign BADASS backpack. This bag is no joke. Straight up. My next purchase will be the spork. Wish you guys would make more styles!!
