Uploaded September 2025 | Updated September 2026, 2 weeks ago

In this video, I used today's sponsor Buyee to hunt down some of the rarest Mizuno tech suits ever made — and the deals I found are insane. After weeks of searching, I finally got my hands on:
🩱 Mizuno GX (2010) – Mizuno’s first ever tech suit
🩱 Mizuno GX-Fits (2012)
🩱 Mizuno GX SONIC II MR (2014)
🩲 Mizuno Stream Ace Brief – FINA approved brief!

I’ll take you step by step through how I find deals on Buyee, give you a full unboxing of everything I bought, and break down the history of the Mizuno GX line — including how these suits shaped the future of sprint swimming.

If you’ve ever wanted to own an elite Mizuno suit without paying full price, or learn the backstory of the GX Sonic series, this is the video for you.

$I Bought a $54 Tech Suit — Then He Won TWO National Titles I bought a £43/$54 second-hand tech suit from Japan using Buyee — a Mizuno GX Sonic III ST — and put it on national-level swimmer Kieran Grant to see if you can win a national title without spending £300+ on a race suit. Spoiler: he won two. This is also a full step-by-step guide to buying cheap tech suits from Japan with Buyee — Mizuno, Arena and models you cant get anywhere else — shipped worldwide.

In the same haul I picked up a rare A6 (£22), a brand-new Arena Aquaforce Lightning (£32), a Mizuno GX Sonic Royal PW (£160) and a brand-new Mizuno GX Sonic 8 MR (£190) — all a fraction of UK retail. Kieran Grant then raced the £43 Mizuno at Nationals and walked away with two national titles and two lifetime bests. The suit doesnt make the swimmer — but you really dont need to spend £300 to race world-class. #techsuit #buyee #mizuno #swimming #gxsonic #cheaptechsuit #swimrace #mizunogxsonic #techsuitreview #nationals$
