The Cole-TAC Flat Bag represents the ultimate minimalist support solution, designed for shooters who need a stable, low-profile platform without the bulk of a traditional bag. Engineered with a slim, rectangular footprint, our Flat Bag provides a rock-solid rest for your rifle when shooting from bench rests, truck hoods, windowsills, or any flat obstacle.
Engineered for the Backbone System
While it works perfectly as a standalone rest, the Flat Bag was purpose-built to integrate with the Cole-TAC Backbone Bag Frame. By attaching the bag directly to your rifle’s Arca or Picatinny rail, you eliminate the need for cumbersome straps over your optic, allowing for lightning-fast transitions between barricades and obstacles without ever losing your rest.
Stability Through Simplicity
The beauty of the Flat Bag lies in its thin profile. It allows the shooter to stay low to the bore axis while providing just enough “give” to allow the rifle to settle in and track perfectly under recoil. Unlike thicker bags that can cause the rifle to feel “top-heavy” or unstable, the Flat Bag keeps your center of gravity low and your point of aim steady.
Tailor Your Support
Personalize your Flat Bag with three distinct fill options designed to meet your specific needs:
UltraLiteFill – Ideal for hunters, field shooters, and competitors, our lightest fill utilizes expanded polypropylene to achieve minimal weight.
CoreFill – Our classic polypropylene fill delivers the ideal balance of weight and flexibility—staying secure while conforming to any surface.
CompFill™ – Engineered in-house, our newest fill blends firmness and adaptability, using added weight to stay planted while reducing movement for consistent, precise shots.
Made in America with the highest-quality materials, our gear is built to last.Â
Have any issues? All our gear is backed by our no BS Lifetime Warranty—get in touch with us, and we’d be happy to make it right!
Whether you are a long-range enthusiast zeroing a new optic or a hunter needing a quick rest on a gate or a rock, the Cole-TAC Flat Bag provides the essential stability you need in a compact, indestructible package.

Great little bag from an amazing company that stands behind their work. I asked for a heavy fill and Cole-Tac did it. The heavy fill is nice and I believe better than the light. Forms around a barricade great. Not too heavy but not too light. I’ll definitely be using this in the deer stand too.

Paired with a backbone, this is a great bag for barriers and out of position shooting. Fantastic quality, great American made product

A well-constructed product using quality material. My only complaint is the new bag is too hard. Wish I had known that I can tell Cole-Tac to make that bag softer. Other than that one issue, the product is awesome.

I paired mine with the back bone and love it on the barricade!

Really like the bag. It would have been nice if who ever packaged it for shipping would have closed the Velcro end to keep the little pellets in the bag
Paul Y (verified owner) –
Very good quality bag!

Excellent product bought bag and backbone arca style, fast shipping and nice Military discount. When I received the items I started to install the bag to the backbone and noticed some black beads on the counter. Took a real close look at the bag and found a very small tear one one end. Emailed customer support and sent some pics to them, I thought I would get a response in a few days but to my surprise I had a return email immediately. They apologized for the defect and sent a new one right away! This is a great company to deal with, they stand behind there products, I will be ordering more items in the near future.

When this bag arrived the stuffing (black beads?) was everywhere. The Velcro wasn’t sealed and some of the beads were stuck in the Velcro. Need better QC.
Used the bag at a match this weekend and things were going well until one of the Velcro straps let go in the middle of a stage. Maybe an extra 1/2 inch in length would help?

Ordered the waxed canvas version it with the Backbone. The Velcro and beads are genius. Why buy Arca or MLok weights when you can fill this with sand or lead shot to perfectly balance the rifle just forward of the magazine well? Ordered on Weds arrived on Sat, shot a match on Sun. Perfect size for tank traps, ladders, saw horses, and tires. American made quality and innovation.

Overall very good little bag for the price. All other bags are rediculously over priced regardless of how well they are made. Which is unfortunate of many of the products in the “PRS/NRL” shooting industry, (i.e. bags, scope rings, bubble levels, throw levers, etc.).
Perfect size and fits well with my MAZ precision arca bag plate. Bag is lightweight so hoprfully it will last, only time and use will tell. Would have given it 5 stars if it had been sewn with double stitching and made of heavier cordura, not the thin stuff. A little heavier cordura and thicker stitching thread doesn’t make the bag much heavier if at all, but will add noticeable durability! You should always double stitch items of heavy wear like “shooting bags” because they are going to be rubbing on rocks, dirt, fences, etc.! For reference, i used to have our guys make deployment bags, rifle bags, etc. and I would have them order a little heavier cordura (by bulk for cost savings), and then double stitch everything of high wear, (ie. shoulder straps, handles, padding, etc.) in order to produce a solid product that would last. The overall cost was negligeable when you order bulk, which i’m sure Cole-Tac and others do.
Cole Tac is a very good company! They listen to the customers needs and charge a fair price on the majority of their products, which is more than i can say about the majority of the industry right now. Hopefully they’ll take this on board and make some necessary changes yet not drive the price up through the ceiling.
I’ve recently tested the bag a little and it seems to be holding up. It is however starting to show some wear. It is definitely worth the cost and a better choice than others for the price.

Great quality and reasonably priced. It worked great on my rifle for PRS competition

I just LOVE this bag. Its light weight and the design to attach it to the Backbone Frame is excellent. I also purchased the Backbone Frame for Picatinny rail and the Frame has an easy detach lever, not the knob as shown on the picture. Easy to attach and take off during stages. (I think the picture on the website needs to be updated so you know that it is not a knob).

Seriously love the fit between the magwell and my vert grip on the Mk12.
This is what spoiled and pampered feels like. QD action with the Backbone makes me feel like one uh them pro-fesshun-al shooters.
Great quality. Looking forward to never using the warranty.
Thanks, Vicki!

Another great product,can’t wait to hit the range.
Jeffrey Davis (verified owner) –
Bag is well constructed and fits backbone perfectly. My only complaint is it is very light. I changed the fill and all is well
Dirk Douglass (verified owner) –
Great bag, I added sand and with Arca Bag Frame attached it to my gun for some added weight.
Dan Tatem (verified owner) –
I have owned their original flat bag and backbone for years. The original version was a bit longer, a bit skinnier and a little thinner. This new design is a big improvement. More surface area and more stable. This set up works awesome with their proprietary backbone system. Very happy! These guys have the best warranty on the market. Any issues you ever have, reach out and they will take good care of you!

I am new to the PRS game and thanks to Cole-tac gear I feel like I’m cheating. This backbone system keeps my bags together and help my positional transitions smooth and uncomplicated. I appreciate having a one-stop shop for my soft stability gear.
