Freediving fins manufacturer · OEM long-blade fins factory since 1993
Vanguard manufactures carbon fiber and high-resilience polymer freediving fins for clubs, dive brands, and e-commerce sellers. Long blades tuned for thrust efficiency, LSR foot pockets, and an interchangeable blade system, all private labeled to your spec from 300 pairs per color.
Launched in 2021, one year after our F-6876 polymer long blade, the F-6877 brought race-grade carbon fiber into a price bracket club buyers can actually stock. Every blade is laid up, cured, and paired with an LSR foot pocket inside our Guangzhou factory. No outsourced blade blanks.
Carbon’s stiffness-to-weight ratio converts each kick into forward drive instead of wasted flex. Divers cover more distance per kick at lower oxygen cost: the single metric performance buyers compare. Because the blade is laid up and cured in-house, we control the spec from weave to finish.
F-6877 blades are produced in graded stiffness options on one foot pocket platform, so a first-time freediver and a deep trainer both find their match. Your shop stocks fewer SKUs, and customers upgrade stiffness within your lineup instead of leaving it for a competitor’s shelf.
Blades detach from the foot pocket in minutes. A damaged blade is replaced without retiring the fin, and divers swap stiffness grades as they progress. For you, that means fewer warranty returns and a repeat-purchase replacement blade SKU that keeps customers inside your brand.
The foot pocket is molded from medical-grade liquid silicone rubber (LSR): soft against the instep, locked at the heel, with no pressure points even during long sessions in thin neoprene socks. Power transfers from leg to blade without the hot spots that end rental dives early.
Carbon for performance buyers, high-resilience polymer for volume programs, and an interchangeable blade system that turns one fin into a repeat-purchase product line. All three share the same QC standard, the same LSR foot pocket platform, and the same 300-pair-per-color MOQ.
The F-6877, launched 2021. High-end carbon fiber blade with adjustable stiffness grades, an interchangeable blade system, and an LSR foot pocket molded for all-day comfort. The flagship your performance buyers ask for by name.
The F-6876, launched 2020. A long high-resilience PP+POM blade that shrugs off rocks, boat ladders, and rental abuse, at a unit price that works for clubs, dive schools, and entry-level retail programs.
Replacement blades and stiffness upgrades for the F-6877 platform. Sell the fin once, then keep customers buying blades. Damaged blades swap out in minutes without retiring the foot pocket.
Blade engineering
Blade material decides the four numbers your buyers compare on every listing: thrust efficiency, weight, stiffness, and price. Here is how our two platforms stack up, and where each one earns its place on your shelf.
Carbon blades rarely fail from the material itself; they fail at air pockets, misaligned weave, and uneven resin inside the layup. Our layup process holds weave orientation and resin distribution consistent from blade to blade, which is exactly where no-name carbon fins snap. Ask any carbon fin supplier how they control layup; the answer tells you who you are really buying from.
A long blade that is too stiff overloads the ankle; one that is too soft dumps energy at the tip. We tune blade geometry and layup so the flex zone loads water through the full kick cycle. Freedivers feel the balance as glide rather than leg burn, and it is the reason large-format blades stay efficient instead of just long.
Because stiffness comes from the layup rather than a different mold, we produce multiple stiffness grades on the same F-6877 platform. Custom programs can spec their own grade lineup without new tooling. That is a private label advantage most carbon fin resellers never get from a trading company.
| Factor | Carbon fiber (F-6877) | High-resilience polymer (F-6876) |
|---|---|---|
| Thrust efficiency | High energy return, more drive per kick | Good efficiency with a softer flex pattern |
| Blade weight | Noticeably lighter on the ankle | Heavier but forgiving |
| Stiffness | Adjustable grades via layup | Fixed by material and blade geometry |
| Impact tolerance | Strong in the designed flex direction; avoid rock strikes | Shrugs off rocks, boat ladders, rental abuse |
| Unit price | Premium tier | Budget-friendly for volume |
| Best channel | Freediving clubs, spearfishing, geek buyers | Schools, rental fleets, entry-level retail |
Not sure which platform fits your channel? Ask our engineers for a recommendation with your quote, because most programs stock both.
From 300 pairs per color, we turn your spec sheet into retail-ready fins. Blade graphics, foot pocket color, stiffness grading, and packaging all happen inside our 27,824 m² Guangzhou facility, managed by a 123-person team with 15 dedicated R&D engineers.
Logo printing on blade and foot pocket, Pantone color matching, and custom finishes that make your fins recognizable on a retail wall or in a listing image.
Mesh fin bags, printed retail boxes, and FBA-ready cartons with batch-traceable labeling. Everything is packed the way your channel requires, not the way our warehouse prefers.
LSR foot pocket color and size grading matched to your market, from youth to adult sizes, all molded in-house on our own tooling for consistent fit across reorders.
Every batch inspected under our ISO 9001:2015 system, with pre-shipment inspection by SGS, Intertek, TUV, or your nominated third party arranged on request.
Custom molds and blade artwork are exchanged only under a signed NDA, stored separately, and never shared with or resold to another buyer. Your private label stays yours. That is the whole point. Pair fins with masks and snorkels from the same factory for a consolidated freediving program.
