COVER FAMILIES

Solid vs Pearl vs Hybrid

Most Columbia 300 covers fall into one of three sub-types within the reactive resin family. Picking the sub-type narrows the search before you drill into specific compounds.

MOST FRICTION

Solid Reactive

Highest oil traction. Reads the lane earliest. Best for heavy oil and sport patterns.

Columbia 300: Atomic Response Solid
BALANCED

Hybrid Reactive

Blend of solid traction and pearl length. The versatile middle-ground cover for medium oil.

Columbia 300: ChaoticControl Hybrid
LENGTH

Pearl Reactive

Glossier surface, less friction in the front. Saves energy for a defined backend break.
