Buy Custom Long John Wetsuits | Sleeveless Farmer John Manufacturer

As a product manager for a sailing, kayaking, or paddleboarding brand, you know the Long John (or "Farmer John") is the unsung hero of watersports apparel.

It offers the perfect solution for temperate conditions: it keeps the user's core and legs warm while leaving their arms completely free for unrestricted paddling, trimming sails, or swimming.

But is the sleeveless suit in your product line a high-performance tool that enhances the user's experience, or is it a restrictive, uncomfortable afterthought made from cheap materials?

The difference between a great Long John and a poor one lies in the details of its construction: the flexibility of the neoprene, the type of seams, and the ergonomic fit.

As a direct manufacturer that engineers these specific garments, let's break down the anatomy of a superior Long John, so you can provide your customers with a product that is truly built for their sport.

Deconstructing the Perfect Long John: A System of Warmth and Mobility

A Long John is a masterpiece of functional design. Its purpose is to solve a specific problem, and its construction should reflect that.

1. The Neoprene Thickness: 2mm or 3mm?

The choice of thickness depends on the intended water temperature and activity.

• 2mm: This is the ideal choice for summer and temperate conditions. It provides excellent flexibility and just enough insulation to protect against wind chill and cool water, without causing overheating during strenuous activity.

• 3mm: This is the workhorse for 3-season use in cooler climates. It offers significantly more core warmth, making it perfect for spring and autumn sailing or kayaking, while still providing good flexibility.

2. The Neoprene Foam: Why Flexibility is Non-Negotiable

For a garment that wraps the entire torso, flexibility is paramount for comfort, breathing, and performance.

• Premium 100% CR (Chloroprene Rubber): This foam offers the absolute best in flexibility and a soft, supple feel. For a premium Long John that feels like a second skin and allows for maximum torso rotation and deep breathing, CR is the superior choice.

• High-Quality SCR Blend: A good SCR blend (with 50%+ CR content) provides an excellent balance of great flexibility and a more competitive price point. It is a massive upgrade in comfort compared to basic SBR.

• Budget SBR Foam: We do not recommend 100% SBR for a Long John. Its inherent stiffness restricts movement and can make the suit feel constricting and uncomfortable around the chest and shoulders.

3. Seam Construction: Matching the Seam to the Season

The type of stitching is a critical detail that determines the suit's warmth and comfort.

• Flatlock Stitch: This breathable, comfortable seam lies flat against the skin to prevent chafing. It is the perfect choice for warm water / summer Long Johns (typically 2mm) where maximum waterproofing is not needed.

• GBS (Glued & Blind-Stitched): This is a waterproof seam, essential for cool water Long Johns (typically 3mm). It prevents cold water from flushing through the seams, keeping the user's core much warmer.
