HDPE Netting vs. Nylon Netting
Nylon netting is ideal for heavy-use, indoor cages as it has the strongest breaking-strength and is by-far the most durable type of netting. Used in most MLB and NCAA indoor facilities, Nylon nets provide excellent abrasion resistance and the best overall durability. Consequently, Nylon netting is typically very expensive.
Nylon is typically not good for outdoor use because it soaks up water. This brings the potential for the netting to rapidly rot, shrink and discolor. As a result, the nylon netting can lose its breaking strength at a rate of up to 20% per year.

While HDPE nets do not have the break-strength of Nylon netting, they do offer a more price efficient option for your indoor or outdoor netting needs.
What twine size is right for my cage?
Normally, netting comes in twine sizes. The larger the number, the thicker the twine. For example, a #42 twine is twice as thick, and twice as strong as a #21 twine. It’s that simple.
