Why the ST2
The Family Favorite
Moderate flex works for different body types and swimming styles — strong enough for an athletic swimmer, forgiving enough for someone just getting started. One system the whole family can share.
Swim + Train
Lap swimming, interval training, resistance workouts, even aqua jogging. The ST2 handles the variety because the two-piece design gives you real flex with real control.
Compact & Easy to Store
At 47 inches, the ST2 sits below standard pool fencing. The two-piece pole separates for storage and reassembles in seconds. Stays out of the way when you're not swimming.
The Right Balance
The ST2's two-piece design (0.75" upper, 0.625" lower) creates a flex profile that sits right in the middle — enough give to feel natural during lap swimming, enough rigidity for resistance training and water fitness.
This is why it's our best seller. It doesn't specialize — it adapts. Whether you're doing 30 minutes of freestyle or a mixed workout with jogging and resistance bands, the ST2 keeps up.
Built to Stay Outside
Same materials as the ST3 — UV-resistant fiberglass, 316 stainless steel fittings, marine-grade EPDM cord. Leave it installed through sun, rain, and pool chemicals. It's designed for it.
The two-piece construction also means if you ever damage a section, you can replace just that piece instead of the whole pole.
What's In the Box
Every ST2 system ships complete: two-piece fiberglass pole, your choice of base, Dynamic Stretch Cord with carabiner, swim belt, and nylon carry bag. Concrete and threaded wood bases also include a rubber plug that caps the base when the pole isn't installed. Nothing else to buy.
Free shipping on orders over $99 in the continental US. International flat-rate shipping available.
