Neoprene. Its thick 4mm stitched construction holds up to repeated use for years, while foam is better suited to shorter-term or one-time use.
Which is better for custom printing?
Neoprene — it takes sublimation and DTF printing best, with vivid color and full wrap-around coverage. See Custom / Sublimation & DTF.
Which is cheaper in bulk?
Foam has the lowest cost per unit, but neoprene also drops to under $1 each in bulk — so you get a premium product for very little more.
Do foam koozies insulate well?
Yes — foam provides good insulation for everyday use. For maximum cold-retention, 4mm neoprene performs best.
Which should I pick for a wedding?
