A debate that many riggers have a firm opinion on, both have their pros and cons. Hardcore Shibari-ists will say that single ply is supreme, while others may reap the benefits of the hard-wearing double ply! It's all down to personal preference.

 

Single ply

My ropes are constructed of a single-stranded yarn, and in a 3-strand twist.

Pros:

• Density: Single ply ropes have less bulk, meaning they will compact a knot nicely and come apart easier.
• Flexible: These ropes tend to be more flexible, allowing for smoother movements and easier knot tying.
• Strength: On a single line pull, single ply ropes win on the measure of strength.
• Aesthetic: Single ply tends to be more photogenic.

Cons:

• More expensive: This is mainly due to the extra labour involved in making the rope.
• Less durable: As the rope is less dense, it's more prone to compacting with age and use. Eventually, some rope will become too thin to use for anything other than floor work.

Double-Ply Ropes:

Pros:

• Increased Durability: Double-ply ropes are more compacted compared to single-ply ropes, meaning they do not thin down as much as their single ply counterparts.
• Enhanced Safety: The added layers provide extra protection against rope burn and friction, reducing the risk of injury during intense or prolonged sessions. 
• Longevity: Double-ply ropes tend to last longer and withstand more wear and tear than single-ply ropes, making them a better investment in the long run.
• Cost: Double-ply ropes are often cheaper than single-ply ropes due to the manufacturing process involved.
• Minimum maintenance - Making 2ply a great choice for beginners and those who want a more forgiving rope, especially for those who are finding they have to replace their rope more than they would like,.

Cons:

Less Flexibility: The additional layers can make double-ply ropes stiffer and less flexible, which may impact their manoeuvrability in handling.
