The dense "craft grade" foam bodies have been the standard for a long time now, but there is finally something better on the market! Our Premium Foam Ant Bodies are made of Upavon Foam, which is about half the weight of the old style bodies, yet it keeps water out almost completely, making them float 10X better! Even without floatant, these will stay on top. Sold in packs of 10. We use the XL exclusively on size 10-12 hooks.
