Custom Monofin Bag Manufacturer — Hard Case & Soft Bag OEM Since 2014
A monofin bag is a specialist carrier engineered for oversized free-diving monofins — protecting the blade, toe plate and rail from transport damage. Because a monofin is rigid, expensive (often carbon fibre) and too long for ordinary holdalls, it needs either a padded soft bag or a hard-shell case built to its exact footprint. At JUNYUAN BAGS we make custom monofin bags — soft, semi-rigid and full hard case — OEM/ODM from our affiliated production base in Quanzhou, China (company established in 2014, founder in the bag industry since 2004). Standard MOQ is 500 pcs, sampling takes 6–10 days and bulk production 35–50 days under AQL 2.5. Monofin is a small but high-value niche with loyal professional buyers, so protecting the asset matters more than price.
Three Monofin Bag Types
| Type | Best for | Protection | Weight |
|---|---|---|---|
| Soft bag | day use, shore | moderate (EVA pads) | light |
| Semi-rigid | travel + air | high (plastic liner) | medium |
| Full hard case | air freight, storage | maximum | heavy |
Sizing — S / M / L by Blade Length
| Blade length | Bag interior | Best fit |
|---|---|---|
| Up to 75 cm (S) | ~80 cm | short training blades |
| 75–90 cm (M) | ~95 cm | standard monofins |
| 90–105 cm (L) | ~110 cm | long / carbon monofins |
