Modern golf ball construction, particularly for USGA conforming balls, utilizes advanced materials designed for low moisture absorption. The core, often a multi-layer synthetic rubber compound, and the cover, typically ionomer or urethane, are engineered to be highly impermeable. While prolonged submersion in water can introduce trace amounts of moisture, typical exposure to damp fairways or dew-covered greens during a round results in negligible weight changes, usually less than 0.5 grams. This minimal absorption ensures that compression characteristics and flight dynamics remain largely unaffected, maintaining performance consistency even in humid or wet playing conditions.

The internal construction of the Amazon Basics Core Soft golf balls is designed to manage impact forces through its advanced core and cover technology. The low-compression core, often a blend of polymer materials, is engineered to compress and rebound efficiently. While direct, forceful impacts on extremely hard surfaces like concrete can exceed the material's elastic limit and cause structural damage, typical impacts during play—even on firm fairways—are absorbed by the composite layers. The cover material, such as ionomer, is formulated to resist shearing forces, ensuring that the ball's intended compression and spin characteristics remain stable for hundreds of such impacts, preserving launch angles and overall playability.
