What They Have in Common
Same brand, same wheel count, same brake, same bag-retention system (Top-Lok), and same warranty. Both include a detachable umbrella holder and a drink-and-phone holder. Both list as three-wheelers with a handle-mounted parking brake, and both carry a two-year limited warranty.
Where They Differ
Folded size — which number matters to you
This is the real comparison. The Compact 3 folds to 21.5 × 13 × 18 in (2.9 cu ft by volume). The Slimfold folds to 32.25 × 8.5 × 13.5 in (2.1 cu ft). The Slimfold is smaller by volume — 0.8 cu ft less — but it's 10.75 inches longer. That's the trade-off in plain terms: flat and thin vs shorter and thicker.
Whether 8.5 inches matters more than 32.25 inches matters comes down to your trunk. If you're measuring clearance from the floor to a hatch lip or a cargo shelf, the Slimfold needs 8.5 in where the Compact 3 needs 13. If you're measuring how far the cart can extend before it hits the rear seats or a stroller, 32.25 in is a real number to check. The Compact 3's longest dimension is 21.5 in.
Fold mechanism
The Compact 3 uses a three-step fold, with the front wheel tucking underneath the frame. The Slimfold uses what Bag Boy calls a two-step open/fold with easy auto-open — that's their phrase for it. Bag Boy doesn't publish open dimensions for it.
Weight and price
The Compact 3 is 13.5 lbs. The Slimfold is 15 lbs. A 1.5-lb gap is a real difference at the tailgate if you're hoisting it twice a round. The Compact 3 lists at $259.95, the Slimfold at $299.95 — a $40 gap at list.
What's in the box
Both include the umbrella holder and a scorecard console. The Slimfold adds a large accessory bag; Bag Boy lists no accessory bag for the Compact 3, unlike its other carts. If you'd use one for balls, tees and gloves, that's a real difference.
Who Should Buy Which
Get the Bag Boy Compact 3 if:
- Your trunk doesn't have a low roof or a horizontal crossbar to negotiate
- You want to save $40 and carry a lighter cart to and from the car
- You don't need an accessory bag and carry what you need in your golf bag's pockets
Get the Bag Boy Slimfold if:
- Your trunk has a low hatch, a cargo shelf, or a flat space that a 13-inch-thick cart won't slide into
- You actually use an accessory bag — it's included here and not listed there
- The $40 premium is fine and you'd rather have the flat-folding option
The Bottom Line
These two are closer than the names imply. Same system, same warranty, same accessories minus the bag. The Compact 3 is lighter, shorter when folded and $40 less — that combination is hard to argue against for most trunks and most golfers. The Slimfold earns its price if you have a trunk that demands a flat, thin shape over a short, thick one.
