Arena ST Next vs. Arena Impulso – Which Racing Suit Should You Choose?

With Arena’s launch of the new Impulso racing suit, our SwimExperts took it straight to the pool deck for a full comparison against the popular ST Next. Both are excellent tech suits for developing swimmers—but how do they stack up in fit, comfort, compression, and durability?

Here’s what our SwimExperts discovered:

Fit & Comfort: Easy In, Flexible Feel

Both suits fit true to Arena’s standard race fit, meaning our swimmers went two sizes down from their training suit. But there’s a noticeable difference in feel:

• Impulso: More stretch and flexibility, thanks to high-quality Italian woven fabric. Easy to pull on, especially around the shoulders—ideal for younger swimmers or those who find the ST Next a little too stiff.

• ST Next: Firmer and more structured. Getting the straps up on the kneeskin takes some effort, and it may feel more restrictive due to thicker stitching.

🧠 SwimExpert Tip: If ease of wear and comfort matter most—go Impulso.

Compression: Moderate with a Competitive Edge

Both suits offer moderate compression, perfect for swimmers new to tech suits or transitioning from practice suits.

• Impulso: Slightly more compressive through the legs, giving swimmers that “locked in” feel without being too tight.

• ST Next: Also supportive but with a lighter feel overall—better for those not yet used to racing suit compression.

Durability & Water Resistance: Impulso Stands Out

This is where the Impulso really pulls ahead:

• Impulso: Woven fabric means better durability, shape retention, and low water absorption—making it feel more like Arena’s elite Carbon series.

• ST Next: A solid entry-level suit, but the fabric can lose tightness with frequent wear.

🎯 Parents, take note: The Impulso’s shoulder straps stretch well to accommodate growing swimmers—more wear time means more value.

Price Breakdown: Performance at Every Budget

• Arena Impulso:

  • Jammer – $220

  • Kneeskin – $300

• Arena ST Next:

  • Jammer – $140

  • Kneeskin – $200

💸 SwimExpert Take: ST Next is great for swimmers still growing. Impulso offers the best balance of comfort, performance, and longevity without jumping to high-end suit prices.

Final Verdict from Our SwimExperts

Both suits have their place, but if you're ready for a comfortable, race-ready upgrade, the Arena Impulso is a standout. It’s a worthy successor to the beloved R-EVO and a great stepping stone toward the elite Carbon series. Whether you're racing for best times or building confidence in competition, the Impulso brings value and performance.
