HYROX & Functional Race Equipment Manufacturer

Functional racing has moved from a niche event to a season. HYROX alone ran more than 80 events in 2025 and has passed 100 for 2026, and the equipment around it — wall balls, sandbag shells, sled leashes, race belts, ropes — is bought by race organisers, race-prep gyms and brands selling to athletes. We make the light end of that kit in Yangzhou, and we ship sandbags empty so a 25 kg bag costs freight like a 1 kg bag.

Materials

What it is actually made of

PU wall ball shell

Seamless rotational-moulded PU over a PP granulate core. A stitched PVC shell is cheaper but splits at the seam after a season of wall contact, which is the failure race organisers complain about.

1,000D Oxford sandbag

Double-stitched with a separate inner liner so the bag holds shape when filled with sand or steel shot. We ship shells empty and the buyer fills locally.

Polyester rope

Three-strand, 38 mm, with a vinyl end cap and a heat-shrink whipping so the rope does not unravel on concrete.

Before you ask

Questions buyers send first

Why ship sandbags empty?
A filled 25 kg bag is a freight problem: volumetric weight, customs questions, and a per-kilo cost that wipes out the margin. We sew the shell and the liner, ship them flat, and the buyer fills locally with sand or steel shot. Carton weight drops from 25 kg to 7 kg for fifty units.
Are your wall balls the weights HYROX uses?
We make 6 lb, 10 lb, 14 lb and 20 lb shells, which covers the men's and women's race standards. Tell us the event rulebook you are buying against and we will match the diameter and bounce spec. Do not print a federation logo without written permission from that federation.
Can you supply one event, not a container?
Yes. Race organisers usually order 40 to 200 pieces per station in mixed sizes. We consolidate balls, bags, belts and ropes into one carton plan so the pallet arrives in the order your venue staff will unpack it.
What is the MOQ?
40 pieces for 50 mm battle ropes, 100 per wall ball weight, 150 for sandbags and sled leashes.
