Ringers Cool Water Expander Pellets are one of the best expander pellets on the market for cooler conditions. These pellets have been created with a lower oil content which means that they work better in cooler conditions as the flavours and attractants are still readily released. This also gives them a slightly lighter colour which many top match anglers favour.
The Cool Water Expander Pellets are available in 4.5mm and 6mm sizes. All three can be prepared very easily using a pellet pump and stay on the hook well.
