Sand-filled hacky sacks are heavier, slower, and “deader,” which makes them stall cleanly and land softly on your foot. Crocheted hacky sacks are lighter and bouncier, which makes them lively for casual circle play but harder to balance for tricks. If you want to learn stalls and freestyle, buy sand-filled.
What the fill changes
The fill is the single biggest factor in how a bag plays. Sand settles and stays put, so when the bag lands on your foot it thuds and holds instead of bouncing off. That predictability is what makes stalls learnable. Crochet and plastic-pellet bags keep more energy — fun for keeping a rally going in a circle, frustrating when you’re trying to freeze the bag on your toes.
The trade-offs, honestly
Sand-filled advantages: better control, softer landings, superior stalling, holds its shape. The one caution repeated across the footbag community — don’t soak a sand bag; a wet sand fill can get lumpy. Spot-clean and air-dry instead.
Crocheted advantages: cheaper, softer shell, very forgiving for young kids and pure circle play. Downside: too light and bouncy for serious stalls, and the open weave collects dirt.
The verdict
For learning tricks and stalls, sand-filled synthetic suede wins — it’s why it’s the default for freestyle. Colorado Footbags fills every bag with purified natural sand inside Ultra Synthetic Suede for exactly this controlled feel; the 14-Panel OG is 58 g, right in the control-friendly zone.

What is the filling in a hacky sack made of? Usually sand, plastic pellets, or metal beads. Sand gives the softest, most controllable feel.
