Selkirk LABS Project Boomstik - Elongated Jack Sock Signature Edition

Players loved the punch of the SLK ERA Power. Now add 14% more exit speed to turn the power dial to the max. The ultimate power paddle has arrived, and it’s bringing the boom. 

Meet Project Boomstik, the latest innovation from Selkirk LABS that rewrites the narrative on power paddles. Forget the status quo of sacrificing durability for power — where the only way to maximize velocity is for the core to quickly deteriorate — because this paddle has power that lasts. Seriously, our engineers keep running durability tests over and over again, but still haven’t been able to take it to failure. 

No core crush. No break-in periods. Explosive power and consistent performance from day one.

What makes it possible? At the center lies the new BoomCore — PureFoam surrounded by an EVA Power Ring and fused together for our most powerful core system ever. The BoomCore has solid feel, a massive sweet spot, and lasting durability — with booming power for hard shots that catch your opponent by surprise. If they blink, they may miss it — this paddle shaves a crucial 25 milliseconds off your opponent’s response window (roughly the blink of an eye). That difference in power turns reachable shots into forced errors.

Project Boomstik also introduces the MOI Tuning System — a new paddle technology that delivers elite performance with a maximum sweet spot and balance, right out of the box. It’s 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. By putting the weight exactly where we want it — shifting mass toward the outer regions of the paddle and increasing the moment of inertia — it stabilizes the paddle during off-center hits. The result is clear: a larger and more forgiving sweet spot to help you get more balls over the net.

This is a paddle that’s impossible to ignore — its booming power will give the ultimate advantage on the court through vicious drives and serves plus InfiniGrit’s enhanced spin. 

Don’t let your opponent get the edge. Get the Boomstik. Feel it. Hear it. Win with it.   

Available in two paddle shapes.

Widebody | Longer Handle & Wide Paddle Shape: The widebody shape features a longer handle for added reach and extra space for two-handed backhands. This shape enhances stability and delivers a more consistent, forgiving sweet spot — especially on off-center hits. Ideal for players seeking the largest sweet spot and a consistent feel and performance across the face.

Elongated | Longer Handle & Longest Paddle Shape: Give yourself a better chance on balls you have to reach for. The longer handle has ample room for two-handed backhands, while the elongated shape delivers greater plow-through and power on every shot.

Orders include a paddle ID and certificate of authenticity. Your paddle is already precisely weighted for a maximum sweet spot and balance, right out of the box.

BoomCore for Solid Feel, Consistent Performance, and Lasting Durability.

The new BoomCore — PureFoam surrounded by an EVA Power Ring and fused together — is our most powerful 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. By putting the weight exactly where we want it — shifting mass toward the outer regions of the paddle and increasing the moment of inertia — it stabilizes the paddle during off-center hits. The result is clear: a larger and more forgiving sweet spot to help you get more balls over the net. The balanced weight distribution means your paddle won’t feel too top-heavy or too light — giving you better control and comfort during play. 

*The MOI Tuning System is semi-permanent and comes pre-installed for optimal performance. Note: Removing could potentially cause damage to MOI parts.

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. This advanced surface ensures consistent performance and a competitive edge, even during extended play.

Octagonal Handle for Better Control.

The upgraded octagonal grip offers greater maneuverability and shot accuracy on the court.
