Pick up two cornhole bags that look identical and they can play completely differently. Almost all of that difference comes down to what's inside.
The two fills
Whole feed corn is the original. Dried kernels, sewn into a duck cloth shell — literally where the game's name comes from. Corn gives a soft, dead landing: the kernels shift on impact and absorb energy, so the bag tends to stay put where it lands.
Plastic resin pellets are what almost everything sold today uses. They're small, uniform, and completely inert. A resin bag lands slightly livelier than corn and slides more predictably, and — critically — it behaves the same way in August humidity as it does in October.
Both are built to the same regulation target: 6 inches square, 15 to 16 ounces.
Why corn loses
Corn is an organic material sitting inside a fabric bag that lives outdoors, and that causes four problems that compound over a season:
- It absorbs water. A corn bag left in dew or caught in a sprinkler gains weight, then dries unevenly. Wet corn also molds.
- It grinds itself down. Every throw crushes kernels a little. Over time the fill turns to powder, the bag loses weight, and it stops flying the way it used to.
- It attracts pests. A bag of feed corn in a garage is exactly what it sounds like to a mouse.
- It can sprout. Rare, but it happens to bags stored damp.
The practical version: corn bags are consumables. If your set lives in a garage or gets left out after a cookout, you'll be replacing them.
Resin has none of these failure modes. It doesn't absorb, rot, compress, or interest rodents. That's the entire reason sanctioned play standardized on it — not because resin plays better in some abstract sense, but because every resin bag weighs the same on day 400 as it did on day one.
What this means for how the game plays
Fill affects the two things that decide points: how far a bag slides after it lands, and whether it stays on the board.
Corn's dead landing is genuinely useful for one shot — dropping a bag where you want it and having it stay there, like setting a blocker below the hole. The tradeoff is that corn doesn't want to slide, so pushing a bag up into the hole is harder.
Resin slides more willingly, which makes the slide-in shot more available and rewards a flat, controlled throw. It also means a bag thrown too hard is more likely to run off the back of the board — the fill punishes overthrowing a little more honestly.
Neither is "easier." They reward slightly different throws.
Dual-sided bags
Most competitive resin bags are also dual-sided: one face is a slicker fabric that slides, the other is grippier and stops fast. Same bag, two behaviors, chosen by which side you land on.
Throw the slick side down when you need a bag to travel — sliding up into the hole, or past a blocker. Throw the stick side down when you want it to stop where it lands, like setting your own blocker or protecting a lead.
Basic backyard bags are single-sided and that's completely fine. It's one less variable while you're still working on landing bags on the board consistently.
Which should you buy?
Buy resin unless you have a specific reason not to. It's what leagues use, it survives being stored badly, and it holds regulation weight for years.
Consider corn if you specifically like the dead landing, you play only in dry weather, and you're comfortable treating bags as something you replace. Some longtime players genuinely prefer the feel — that's a legitimate reason, just go in knowing the lifespan.
Whatever you choose, keep the set matched. Mismatched bags within a set are worse than old bags, because every throw needs to feel the same. Four bags per side, all the same fill, all the same age.
Making them last
- Store them dry and out of direct sun. UV kills stitching faster than play does.
- Brush dirt off rather than soaking them; air-dry flat if they do get damp.
- Replace when seams open, when the fill has visibly settled, or when the slick side has worn grippy.
Bags are the cheapest part of a cornhole set and the part that most affects how the game feels. When yours stop behaving consistently, replace them — you'll get more out of that than any change to your throw.
