    Versatile and Rugged

    I've been using this sack for my IFAK since 2021 as a part of my go to gear. When it's not being used on me with my plate carrier and belt, I usually keep it in my truck clipped to my headrest. It's unobtrusive and moves out of the way easily. I recently also took this for a trip across Europe, using it as a secure way to keep my property in front of me away from pickpockets. I had to put a piece of steel cable through the plastic clip so people wouldn't just unclip and run away with it, but it's been excellent. Just barely enough room for everything I need, meaning it doesn't take up more space than I need it to. Bravo Spiritus for such a useful piece of kit.

    Fanny Sack is the BEST (God's Plaid)

    I have had this for over a year now, (Wife got it for me for Christmas). I am an avid runner and wear this to hold my phone and other goodies. It goes with me on every run, it is lightweight and durable. It went to Italy with us too, I recently ran a marathon and it stored my phone, anti-chafe stuff, and a buttload of snacks to refuel with. It's got room as well for my 43X. Getchu' sum.

    Fanny Sack Pouch MK3

    The clip is snappy and secure, fanny doesnt come loose when set to the desired length, The interior velcro makes the entire sack able to be way more organized. Its also confirmed that this will fit a 509c w/optic & light with room to spare. wish I could give this 6 stars...

    Good kit...BUT !

    So ! I had the SACK MK3 for almost 6 months, my very first Spiritus product and it arrived on time but missing the shock cord, no biggie, i got em´ a week later, after that i use it in a more civilian role, i don´t carry a gun in it but i do carry a TQ, medical equipment, tools and other goodies, is just enough space for a compact IFAK, multi-tool, knife, power bank, and some other stuff to be more precise. For the actual review, is a great simple design, i love the color choices, mine is grey for more of an urban role, it has a lot of modularity within, thanks to the big Velcro field, you can configure it as a med bad, as a tool bag, as an EDC fanny, it is the Lego of the fanny packs in that regard. BUT, some of the stitching around the flaps that are fixed to the bag itself did stretch over time after some running and daily use, some frayed threads here and there, the materials is durable for what it is but it get kinda fuzzy with time and the strap could be better. Overall, just buy it, is worth it...I would change to a thicker more durable material for heavier equipment, a thicker strap so is comfier when your wear it as an over the shoulder bag, more durable stitching and that´s it.

    Best and most used Fanny pack I have.

    Have carried this for over 2 years now. Highly recommended! Configuration can be changed quickly with the internal hook & loop. Can be carried crossbody comfortable as well. Holds more than you think it will. Enjoy!

    Get it.

    Used in the field and actually USED in the field. He Fanny is amazing. Just get it. What I’ve used it for is all my reports, extra patches to put on the inside to the Velcro, extra set of batteries, and chem lights. The loops on each side are amazing and add that extra versatility to add on clips and tie downs. Just get one.

    Excellent

    I was looking for a fanny pack for awhile and I found that the majority were either massive, too small/flat, or just really bad quality with poor design. Saw this, knew I had to have it, and I haven't regretted it. The larger pocket is the perfect size for a 365 XL and a few magazines, or several Cliff bar sized snacks, or just all of the stuff you normally want to put in your pockets but can't. The available organizers are great quality and very stiff, and they actually add some rigidity to the shape of the pack to help both conceal the contents and give them a bit of protection. I got the 3 and 4 loop organizers and both are very versatile but I wished I pick up the chemlight and battery inserts as well (you should just buy them all). I like that there's enough loop material on the inside though that I can make my own organizers if it came down to it. The bungee straps are also perfect for a water bottle, a rolled up poncho, or a TQ for the range days. My only complaints are that I think the pouch could afford to be 1 inch wider and a half inch taller. Anything larger than a 365XL/Glock 19 is going to have trouble fitting in this with a holster keeping it angled for a good draw, especially if you have a light on it. I think a slight size increase would also make the flat front pocket a bit more accommodating for most phones to fit in it, as would allowing for some extra slack/expansion. The current iteration will not fit a modern-sized smartphone + case in the front pocket, which makes it not as great for general purpose EDC if you're trying to keep your phone out of your shorts/pants pockets. That being said, they could release a new, ever-so-slightly larger version and I would buy it in a heartbeat and use them both until they disintegrate in 35 years.

    Great for EDC

    This Fanny pack fits my Sig P365XL perfectly! It is a suitable option for CCW if you would rather wear athletic clothes or another outfit that doesn’t quite fit the classic belt and holster. This is also perfect to carry other essential items on the go. Great purchase

Description

The "Fanny SACK" bridges the gap between our popular SACK Pouch and every day carry. Wear it for a full mission profile, or stash your carry gun in it while you're out in town. 

The Fanny SACK was designed to make critical equipment easy to access from both sides or when in a confined space like a vehicle. The Fanny SACK can also be worn on the lower back and out of the way but quickly slid around the waist when needed. 

The pouch features a "half zip" design, which means that your equipment will not easily fall out of the pouch even if the zipper is left unsecured. 

The front of the pouch features a small zippered stash pocket that is perfect for easy access to small items. The bottom of the pouch features two elastic loops that can be adjusted to hold a Tourniquet or other equipment that you may need to rapidly deploy. If bottom carry doesn't fit your mission needs, you can easily remove and reinstall the loops as necessary.

Each side has a webbing loop for attaching equipment such as Gloves, carabiners or Chem Lights. 

The inside features soft loop fields on both sides. This makes the pouch very dynamic, giving you the ability to use our Pouch Insert Suite to fit your requirements. It also features two slide-locks that make it easy to adjust the tension of the elastic loops hanging below, as well as two internal tie-down loops for securing sensitive equipment. The two grommet holes on the bottom aid with drainage of the pouch, if submersion occurs.  

The Fanny SACK is designed to be worn around your waist.
