Selkirk Project Boomstik - Jack Sock

BoomCore™ for Explosive Power and Relentless Durability.

The new BoomCore — PureFoam surrounded by an EVA Power Ring and fused together — is our most powerful foam core system ever. Alongside a massive sweet spot, this core packs a powerful punch with unrivaled durability. No core crush, no break-in period. Explosive power without compromise.

MOI Tuning System for Maximum Sweet Spot and Balance, Right Out of the Box.

Selkirk’s MOI Tuning System is an overall design approach that includes a semi-permanent perimeter weighting solution that balances mass distribution with precision-engineered weights clamped to the edge guard. The result is clear: a larger and more forgiving sweet spot to help you get more balls over the net.

InfiniGrit™ Surface for 3x Spin Durability Over Raw Carbon.

The InfiniGrit Surface technology triples the durability of traditional embossed epoxy peel-ply texture raw carbon surfaces while significantly enhancing spin potential, allowing players to achieve up to 2,000 RPMs for more precise and controlled shots.
