This page starts after the age test
The balcony will still try to make this a shopping panic. Someone’s older sibling has a teal Primo. The heat sheet looks official. A parent hears “tech suit” and opens a till before they have a textile they trust.
If the swimmer is still on the wrong side of the birthday, or the coach has not named a championship, or you do not yet know the textile PB, leave. That job is tech suits for age-groupers. I am not reprinting the federations, the four-property definition, or the Level 1 lecture. I am assuming you already passed it.
What remains is a family choice. Arena Carbon and Powerskin. Speedo LZR. TYR Venzo. Mizuno GX SONIC 6, which I am including because Mizuno’s own pages print World Aquatics approval and a barcode, not because a forum whispered Japan. Training jammers are a different object. This page does not sell Tuesday lycra.
A Carbon on a Level 1 50 free is wedding shoes in the supermarket. Arena’s own Carbon finder is blunter than most parent chats. If you want to race relaxed just for fun, or you are younger than 12, you do not need any compression. That is Arena, not me inventing a morality.
How to read this table
I am not scoring 9.4 out of 10. Factories do not swim your 200 IM. SwimOutlet’s 2025 to 2026 elite review split the rack into thin all-rounders and denser, taped sprint tools. That split is useful. Their 1-to-5 grid is theirs. I am repeating manufacturer jobs, not minting a Finzy league table. Compression is a sensation. Flexibility is whether a breaststroker can still kick. The coach owns the stroke. You own the till, the size chart, and the log note.
Same logic as championship racing goggles. This skin for the same final. Tuesday still wears the club textile.
| Family | What the factory says it is | Wrong use |
|---|---|---|
| Arena Carbon / Powerskin | Core FX locks with Carbon Cage. Primo is Hyperforce, not carbon. Glide targets. Air2 is the light banded Carbon | Buying “a Carbon” by colourway, or sizing down Primo for more squeeze |
| Speedo LZR 2.0 | Intent: dual-layer power. Valor: lighter, moderate compression, more movement | Assuming every LZR is the 2009 polyurethane story. These are textile 2.0 skins |
| TYR Venzo | Surface Lift, Endo Max cage, Seamless Exo Shell. Low waist or high waist | Treating Venzo as a training jammer because TYR also sells daily kit |
| Mizuno GX SONIC 6 | NV, CR, and ET. Sonic Light Ribtex, Sonic Line taping, World Aquatics barcode | Ordering a PFAS SKU into a US state Mizuno will not ship |
Arena. Carbon Cage, then Primo
Parents still say Carbon the way they say Hoover. Arena’s 2025 to 2026 race rack is several objects. Powerskin Carbon Core FX is the one Arena titles their most compressive race suit. Horizontal and vertical carbon fibre grids. Twin tape on the back of the legs for a lift they say holds when you tire. Internal taping and lining for a locked-in core. The UK jammer page, product 003659, still prints FINA APPROVED on that letterhead. Same governing body, old stamp. Arena’s finder puts Core FX at extreme compression. Sprinters. Not the “race relaxed” column. A 400 IM who already hates a squeeze should not copy the balcony sprinter.
Powerskin Primo is not a Carbon. Arena calls Hyperforce the first tensoelastic race fabric. Highest compression plus stretch, permanently hydrophobic TPU fibre, flow-channelling surface, internal X-tape, waist they say you can sit low or high. The US jammer, 006962, is $450 on 23 August 2026 and prints World Aquatics approved in those words. The UK shop lists the jammer at £366 and the open or closed kneeskin at £550. Arena’s wear-test line is 8 out of 10 of 287 US college swimmers keeping it as their main race suit. That is Arena’s trial, not a stopwatch I ran. They tell you not to size down. If it is a wrestling match, you bought the wrong size, not extra speed.
Carbon Glide, product 003665, is the densest carbon grid plus a Hydroglide shell Arena calls ultra-light and low-drag. Targeted compression, not the all-over Core FX lock. UK Arena listed the men’s jammer at £280. US women’s Glide still sat at a $550 list, sale from about $275. Nails off the fabric. Pull from the seams. Carbon Air2 is the paper-light Carbon with horizontal bands and a one-piece shell. Flexibility end of the map. Distance, mixed strokes, people who found Core FX unlivable. Still a tech suit. Still wasted on a Level 1.
Speedo LZR Intent 2.0 and Valor 2.0
The LZR name still carries 2009 in the balcony. These 2.0 skins are textile Fastskin race suits, not that polyurethane era. Both lines print a Lamoral Space Tech water-repellent finish. Both US and UK pages say fully approved by World Aquatics.
Pure Intent 2.0 is the denser LZR. Compressive dual layers. Seams Speedo says connect key muscle groups for power return. Textured drag zones, triple fabric, bonded seams, precision leg grippers. Regular-waist copy says breaststroke and IM may prefer that cut. US list on 23 August 2026 sat at $454 for the men’s jammer and $674 for the women’s openback kneeskin. UK Speedo printed Intent 2.0 jammers at £340 list, sale colourways from about £231 to £272.
Pure Valor 2.0 is the lighter cousin. Moderate compression, more range of movement, compressive inner-leg seam. UK black/red jammer was £250 list and £150 in the 40% sale sticker, out of stock on the SKU I opened. US Valor jammer from $424, women’s openback $574. If the coach said “a Speedo” and they are not chasing max lock, try Valor first. Intent is for a body that already likes a denser suit.
TYR Venzo
Venzo is TYR’s flagship cage, not the daily jammer in the same catalogue. TYR’s US copy is specific. Ultra-smooth fibre they call frictionless. Surface Lift Technology, water not meant to soak the fabric. Endo Max Compression Cage around abdominals, obliques, and quads. Seamless Exo Shell. 70% nylon, 30% elastane. Made in the USA of imported goods. The solid Non-PFAS low-waist jammer is $450, and TYR prints 145gsm and FINA Approved. High-waist Venzo is the same money. If a low waist dumps water at the hip, change cut, not brand. Stiff is a fit fact. If the kick dies, you bought the wrong cage.
Mizuno GX SONIC 6, verified
Mizuno is not a rumour. GX SONIC 6 NV, Noble Velocity, is on Mizuno USA with Sonic Light Ribtex UW fabric, Sonic Line Design VI taping for the kick, Flat Swim Technology for a flat line, and this sentence in plain type. Approved by World Aquatics for national and international competitions. Unique World Aquatics barcode on the swimsuit. Mizuno Europe repeats the barcode line on the NV pages. That is why it is in this table.
NV is the compression and kick-support model. CR, Compression Release, is the mobility cousin at the same $300 sale and $410 list I saw on NV. ET sits with the thinner all-rounders in SwimOutlet’s 2025 to 2026 split. Same family, different job. Do not first-wear NV in a 400 IM final because a sprint account called it the fastest jammer on earth.
Mizuno USA also prints a legal line. The product contains intentionally added PFAS under 100 ppm for water-repellency, and it is not for sale or shipment to California, Maine, New York, or Vermont. If you live in one of those states, the till will refuse the SKU. That is a shipping rule, not a rumour that Mizuno is unapproved.
World Aquatics keeps the list of approved swimwear. Arena, Speedo, TYR, and Mizuno print approval on the SKUs above. The list is still the authority for a WA-level meet. Scan the garment. FINA-labelled suits remain valid at World Aquatics events, in Arena’s own Primo wording. A marketplace listing that says “racing” is not a homologation mark.
Check the list, then the meet pack
World Aquatics does not pick your child’s birthday. Coverage, textile materials, and the approved list are the WA job. Age-group bans are national, and that argument lives on the when page. I opened World Aquatics’ approved-swimwear page and the searchable list. I am only claiming World Aquatics or FINA where the factory printed it on 23 August 2026. Arena Primo US, Speedo LZR 2.0, Mizuno GX SONIC 6, TYR Venzo FINA Approved on the US Non-PFAS jammer, Arena Carbon pages still mixing FINA and World Aquatics by locale. If the championship can take a record to WA, check the SKU the week you buy.
What the tills said on 23 August 2026
Official shops and SwimOutlet, same morning. Sale stickers move. Lists do not make a suit faster. Ranges, not a fake RRP I invented.

One championship. Then rinse
A tech suit is a few races if you are lucky, not a season of Tuesdays. Chlorine eats the finish. Nails eat Glide. Put it on at home once, with the size chart, with help. Then keep it for the meet the coach named. Arena’s care line is rinse in non-chlorinated water, no wet kit-bag stew, hand wash, no heat. Speedo, TYR, and Mizuno live on the same idea. Do not train main sets in it to “get used to the squeeze.” You get used to a dying coating. A dive set the week before is enough.
Measure. Use the brand chart. Arena Primo says do not size down. Glide says pull from the seams. TYR Venzo is meant to be compressive to the point of a second skin. If they cannot finish a 50 in it on a Thursday, they will not grow into it on Saturday. Change size or change family.
The suit is a footnote. The textile is the archive
A suited swim is a real swim. It is not the textile PB. Compression can shave a bit for a developed racer. It can also just feel faster, which is a mood, not a new clock. Write the note. They raced in a tech suit. Finzy has no suit-versus-textile toggle. Seed from the textile. Arena, Speedo, TYR, and Mizuno sell a weekend. The log keeps the season.
The Carbon is a footnote on one championship. The textile PB is the line Finzy still has to keep.
