How to develop a private-label wetsuit with a Chinese manufacturer.

1. Start with a clear product brief

A factory can only quote and sample accurately when it understands what you are building. Your brief does not need to be a full technical pack, but it should answer these questions:

• Product type: full suit, shorty, two-piece, kids’ suit, or accessories such as socks, gloves, hoods and boots.
• Intended use: diving, surfing, freediving, spearfishing or general water sports, and the typical water temperature.
• Target market: where the product will be sold, which affects size charts, labelling and testing.
• Size range and fit: adult, women’s or kids’ sizing, plus any reference garment you like.
• Design and branding: colors, prints, logo artwork and where the logo goes.
• Quantity and packaging: estimated order quantity per style and how each piece should be packed.

If some details are still open, say so. A good factory will help you decide during development instead of guessing. You can send this information through our project enquiry form.

2. Choose the neoprene and thickness

Neoprene foam is usually laminated with a fabric such as nylon on one or both sides. Common foam types you will hear about are:

• CR (chloroprene rubber): the original neoprene, generally positioned as the premium option.
• SBR: a cost-effective foam widely used for entry-level suits and accessories.
• SCR: a blend positioned between SBR and CR.

Thickness follows water temperature and activity. Thinner suits, around 1.5 to 3 mm, are used in warmer water; 5 mm and 7 mm suits are used in colder water or for longer dives. Surf wetsuits are often described with two numbers, such as 3/2 mm, meaning a thicker torso and thinner limbs.

To compare real examples, see the reference specifications for our KKQ-024 hooded diving wetsuit (3, 5 or 7 mm) and our camouflage spearfishing suits (3 and 5 mm).

3. Decide on seams and zippers

Seam construction affects comfort, warmth and cost:

• Flatlock stitching joins panels with a flat, comfortable seam. Because the needle passes through the neoprene, a little water can enter, so it is typically used for warmer-water suits and accessories.
• Blind stitching glues the panels first and stitches without fully piercing the neoprene, which keeps the seam more water-resistant. It is typically used for thicker, colder-water suits.

Zipper position is a design decision too: back zips are easy to put on, front zips (chest zips) can reduce water entry, and some two-piece freediving and spearfishing suits use no zipper at all. Our KKQ-044 two-piece wetsuit is an example of a zipperless, blind-stitched design with a smooth rubber interior.

4. Agree on branding and customization

In an OEM or ODM project, the following can usually be specified with the factory: materials, neoprene thickness, colors, sizes, patterns, logos and packaging. Ask the factory to show logo placement on the sample rather than only on a drawing, and confirm whether your colors are achievable on the chosen material.

If you do not have your own design yet, starting from an existing style is often faster. Browse our OEM and ODM customization examples to see printed and color-blocked designs developed for different ranges.

5. Approve a physical sample

Never move to bulk production without approving a physical sample. When the sample arrives, check:

• Fit on a real person in your core sizes
• Seam quality, glue lines and stitch consistency
• Zipper function and finishing at the collar, wrists and ankles
• Logo position, size and color
• Labels and packaging

Write down every correction. The approved sample becomes the reference that production is checked against.

6. Plan the order around the MOQ

Minimum order quantities differ between factories and products. At YALISI SPORTS the MOQ starts at 100 pieces. If you are testing a new market, consider launching a small number of styles in a focused size range, then expanding once the first order sells through. Sampling and production timing are confirmed after the requirements and approval process have been reviewed, so share your target launch date early.

7. Check quality and compliance documents

Ask which test reports exist for the materials and products you plan to sell, and check that each report matches the style it describes. YALISI SPORTS publishes its documented records, including a CE conformity attestation for diving suits under the EU General Product Safety Directive and independent textile safety tests to GB 18401-2010. For children’s products, our KKQ-028 kids’ one-piece suit was also tested to GB 31701-2015, Class B. Details are listed on our certifications and compliance page.

8. Evaluate the manufacturer

Before you commit, look for evidence rather than claims:

• Real factory photos or a factory visit, not only product renders. You can see our production floor, cutting room and sample showroom.
• Company registration details you can verify.
• Registered trademarks if you are buying an existing branded style. YALISI is a registered trademark (No. 52001083) owned by Dongguan Kukejiala Sports Goods Co., Ltd..
• Sample quality and how clearly the team documents corrections.
• Communication: clear answers in your language and a single contact who follows the project.
