Neoprene Drysuit Suppliers

Neoprene Drysuit Manufacturer and Supplier

As a dedicated Neoprene Drysuit manufacturer and supplier based in China, Jiangsu Yiheng Sports Products Co., Ltd. designs and produces drysuits engineered for cold-water environments. Our range covers professional diving, marine engineering, scientific research, and ice diving, with a focus on thermal protection, durability, and reliable sealing.

We integrate neoprene fabric development with finished garment manufacturing, allowing us to control material quality, production consistency, and customization from our 15,000 m² factory. Whether you need standard models or OEM/ODM development, our team supports you from specification to serial production.

Our Neoprene Drysuit Range

We offer a selection of neoprene drysuits tailored to different operational demands. Each model is built with closed-cell foamed neoprene laminated with airtight fabric, featuring neck and wrist seals plus an airtight zipper for complete water isolation.

Material and Construction

Our drysuits use high-density specialized neoprene for maximum thermal insulation and compression resistance. For cost-sensitive projects, we can specify regular-density neoprene, which offers lower density and higher buoyancy but with reduced performance under pressure. We select the material based on your working depth, water temperature, and budget.

• Closed-cell foam: Provides inherent buoyancy and insulation without water absorption.
• Airtight lamination: Ensures complete water tightness when combined with seals and zippers.
• Reinforced seams: Taped or welded seams for long-term durability in harsh conditions.
• Exhaust valves: Allow air purging to control buoyancy and reduce squeeze.

Application Fit

Neoprene drysuits are designed for low-temperature water environments where wet suits are insufficient. They are not intended for warm waters. Typical applications include:

• Professional diving: Deep dives, cold-water expeditions, and underwater construction.
• Marine engineering: Long-duration underwater operations requiring sustained body heat.
• Scientific research: Data collection in polar or sub-zero conditions.
• Ice diving: Extreme cold environments where reliable thermal protection is critical.

Customization and OEM/ODM Services

We support private label and custom development. From material selection to final design, we work with your specifications to create drysuits that meet your brand's requirements. Our integrated production line—from splitting and lamination to sewing and finishing—ensures traceability and consistency.

We can adjust thickness, color, logo placement, and add features like integrated hoods, pockets, or specific valve configurations. For bulk orders, we provide samples for approval before mass production.

Quality Assurance and Compliance

Our factory operates with a closed-loop quality system, from incoming raw material inspection to final packaging. We hold BSCI, ISO 9001, and ISO 14001 certifications, supporting standardized management and environmental responsibility. Each drysuit undergoes pressure testing and visual inspection to ensure water tightness and workmanship.

Information We Use to Configure Your Solution

To prepare an accurate quotation and sample, please provide the following details:

• Target water temperature and depth: Determines neoprene thickness and density.
• User body measurements: Height, weight, chest, waist, hip, and shoe size for sizing.
• Application type: Ice diving, marine engineering, scientific research, etc.
• Required features: Hood, boots, pockets, valve type, zipper placement.
• Quantity and packaging: Standard or custom packaging for retail or bulk.
• Branding: Logo placement and color preferences.

Maintenance and Service

Neoprene drysuits require proper care to maintain performance. We provide care instructions with each order, including rinsing with fresh water, drying away from direct heat, and periodic seal replacement. Our team can supply spare seals and zippers for long-term serviceability.

Frequently Asked Questions

What is the difference between a neoprene drysuit and a breathable drysuit?

Neoprene drysuits provide inherent insulation and buoyancy, making them ideal for cold water without additional undergarments. Breathable drysuits are typically lighter and allow moisture vapor to escape, but require separate thermal layers. Neoprene is more durable and easier to repair, while breathable suits offer more flexibility in layering.

Can I get a custom size or fit?

Yes, we offer made-to-measure services. Provide your body measurements, and we will adjust the pattern to ensure a comfortable, watertight fit. This is especially important for professional divers who spend long hours in the water.

What thickness of neoprene is best for my application?

For water temperatures below 10°C, we typically recommend 7mm or thicker. For 10-15°C, 5-7mm is suitable. Our team can advise based on your specific conditions and dive duration.

Do you provide samples before bulk production?

Yes, we can produce a sample for your approval. The sample fee is refundable when you place a bulk order. This allows you to verify fit, quality, and features before committing to mass production.

What is your typical lead time?

Standard in-stock models ship within 1-3 days. Custom orders typically take 7-15 days for production, depending on complexity and quantity. We work with your schedule to meet project deadlines.
