Before choosing your leash, it's important to understand its key components:
1. Ankle Cuff
- Connects the leash to your ankle or calf
- Features comfortable padding and secure Velcro closure
- Should include quick-release mechanism for safety
2. Swivels
- Prevents tangling during use
- Double swivel system provides optimal performance
- Constructed from corrosion-resistant materials
3. Leash Cord
- Main body of the leash
- Available in various lengths and thicknesses
- Made from durable urethane or recycled materials
4. Rail Saver
- Protects your surfboard's rail from damage
- Connects to your board's leash plug
- Features reinforced construction for durability
The Right Surf Leash Length
A properly sized surf leash ensures both safety and optimal performance
The golden rule for leash length is to match your board's length. Here's a detailed breakdown:
- Shortboards (5'5" - 6'4"): Use a 6' leash
- Mid-length boards (6'5" - 8'0"): Use a 7' or 8' leash
- Longboards (8'0" and up): Use a 9' or longer leash
Choosing the Right Thickness
7mm thickness provides the optimal balance of strength and flexibility for most conditions
Leash thickness affects both durability and drag in the water:
- 5-6mm (Competition):
- Minimal drag
- Best for small waves
- Suitable for competitive surfing
- 7mm (Standard):
- Balanced performance
- Ideal for most conditions
- Our recommended thickness for daily use
- 8mm+ (Big Wave):
- Maximum strength
- Essential for powerful conditions
- Recommended for waves over head height
