Who I Am & How I Tested This Suit

I'm Sonny, a competitive swim coach and founder of TheSwimsuitGuy, where I've been reviewing tech suits for the past decade. Previously, I coached at Energy Standard in the ISL and have tested every major racing suit on the market. I put the Arena Primo through rigorous testing across multiple race distances and training sessions to give you this honest review.

The Arena Primo arrived in sustainable, premium packaging — a nice touch that tells you Arena took care with this flagship release. What I discovered inside genuinely impressed me. This suit represents the most significant departure in Arena's lineup since 2012, and for good reason.

What Makes the Arena Primo Special:

Hyperforce Technology

Here's what separates the Primo from everything Arena has done before: it's the first arena suit in 12 years without carbon fibre. Since releasing the Carbon Pro in 2012, every Arena suit has featured some variation of carbon. The Primo breaks that tradition entirely, and the reason will blow your mind.

The Hyperforce Difference

The core innovation is hyperforce — a proprietary material Arena has pioneered by weaving together nylon, spandex, and this revolutionary new fibre. Originally developed for medical and athletic compression wear, hyperforce brings something unprecedented to competitive swimwear: the property of tenso-elasticity.

Here's what that means in practical terms: When you stretch hyperforce, it doesn't lose compression. Unlike traditional materials that loosen off when stretched, hyperforce maintains its grip while offering significantly more range of motion. Arena measured this extensively — they actually hired someone from a compression wear company with a device that quantifies compression levels. The results are stunning: the Primo delivers more compression than even the Core FX, while feeling noticeably more comfortable.

Easier to Put On, Harder to Take Off Your Body

I initially got the Primo in a size 26, and honestly, it took me 10 minutes to squeeze into. It felt uncomfortable and overly tight. Arena listened to my feedback — they told me there's no need to suffer — and sent me the size up. I tested both sizes 28 and 30, ultimately settling on the 28 as the sweet spot. Here's the remarkable part: at a size 28, the suit slides on in just a few minutes, feels comfortable immediately, and compression readings confirm it's delivering the same championship-level grip as the oversized version. You get active muscle compression without the pain-to-dress cycle of previous flagship suits.

Material Quality & Durability

The material has a substantial but lightweight feel — not as thin as the Carbon Air, but definitely not heavy. It has excellent snap and doesn't feel flimsy. Because hyperforce is engineered for durability, this suit will outlast previous Arena models. Arena stress-tested this material through hundreds and thousands of stretches; it maintains its stretchiness and compression properties throughout its lifespan. They've even patented hyperforce, giving them full proprietary ownership — no other brand can use it.

Permanent Water Repellency

Previous Arena suits relied on durable water repellent (DWR) treatments sprayed onto the fabric, which deteriorated after a few races. The Primo takes a different approach: every single yarn and thread is treated with hydrophobic TPU coating before being woven into the suit, then treated again after construction. This double-treatment makes hydrophobicity permanent. The suit stays remarkably dry throughout racing and after multiple uses.

Premium Lining & Design

Arena included a full interior lining made from a softer material than the exterior, which significantly enhances comfort against your skin. The new taping system is refined for fit and structural integrity rather than flashy design. Currently available in two colorways — black with teal accents and neon green with purple and pink taping — both look sharp.

Pros & Cons

Pros:

• Best-in-class compression without the difficulty of getting dressed

• Exceptional comfort from the moment you put it on — no creasing, rubbing, or chafing

• Versatile performance across all race distances (50m through 1500m+)

• Superior durability compared to previous generation suits

• Permanent water repellency that doesn't degrade over time

• Genuine active muscle compression that athletes report makes them faster

• Proprietary hyperforce material unavailable from competitors

Cons:

• Premium price point at $450 — not accessible for recreational swimmers

• Not the absolute thinnest suit available (Carbon Air edges it out there)

• Sizing requires attention: compression levels are so precise that size selection matters significantly

• New technology means long-term durability data is still emerging

Fit & Sizing Guide

The Primo's fit is Arena's best since the Carbon Air — and honestly, I'd argue it's more comfortable. Unlike the Core FX where I occasionally noticed creasing at the knee or rubbing on the hips, the Primo feels smooth from the moment you put it on through the moment you take it off.

Sizing matters with this suit. The compression and tenso-elasticity properties mean that one size down might feel extremely tight, while one size up won't give you the compression you paid for. If you're between sizes, I'd recommend ordering from a retailer with good return policies so you can dial in the perfect fit.

Who Should Buy This & Who Should Skip It

Perfect For:

• Competitive swimmers at any distance looking for one flagship suit that does it all

• Athletes who struggled with previous flagship suits due to comfort issues

• Swimmers prioritizing durability over just raw performance

• Serious competitors where the investment in championship-level equipment is justified

Consider Something Else If:

• You're on a tight budget (the $450 price is significant)

• You exclusively race 50m events and want absolute maximum taper

• You need the absolute thinnest possible material (Carbon Air is slightly thinner)

• You're a recreational swimmer not competing at high levels

How It Compares to Other Top Suits

Primo vs. Mizuno GX Sonic 6 NV: The Mizuno is outstanding for 50m racing — more taping, more compression, more specialized. But that specialization is its limitation. While the Primo works beautifully from 50m through 1500m, the Mizuno starts feeling fatiguing in 100m races. If you want one versatile suit, the Primo is your choice.

Primo vs. Speedo: It's not even close. The Primo is simply in a different league.

Primo vs. Arena Carbon Air: The Carbon Air is slightly thinner, which some sprinters may prefer. But the Primo delivers superior compression, better comfort, and genuine versatility across all distances. If I had to choose one suit, it's the Primo every time.

Real-World Testing: A Convert's Story

One of my coaching clients, Chad, has been an absolute faithful to the Carbon Air since it was released. I used to give him grief about it, suggesting he'd go faster in the Core FX for longer distances. He'd always refuse, saying the Core FX wasn't comfortable enough for him. When the Primo released, Chad made the switch. That tells you everything you need to know — it's the first suit in years that convinced a Carbon Air loyalist to try something new.

Final Verdict: Worth the Price

The Arena Primo is the best tech suit on the market right now. Arena's decision to move away from carbon fibre and invest in hyperforce technology has paid enormous dividends. This suit delivers championship-level compression in a more comfortable, more durable package than anything they've produced previously.

Is $450 steep? Yes. But if you're a competitive swimmer buying one flagship suit, this is the one. It handles sprinting, middle distance, and distance racing with equal excellence. It's comfortable enough to wear confidently in heats and finals. It'll maintain its performance over multiple seasons. And it'll make you faster — not just in theory, but through genuine active muscle compression that serious swimmers can feel the difference.

If you're looking to invest in competitive swimwear, the Primo is the clear choice. I'd recommend it without hesitation to any athlete serious about their performance.
