If using detachable bag straps for a heavy item, please keep in mind that we recommend only holding 1/3 of the breaking strength of the weakest part of the strap. For example, LWP 2" has a breaking strength of 1200lbs. However, a plastic swivel snap has a breaking strength of only about 100 lbs. So, with plastic hardware, you would not want to exceed about 30 lbs in your bag. Using metal hardware would increase your capacity to maybe 100 lbs. These are not Cargo Bag Straps. You would almost never haul around more than 40-50 lbs on your shoulders or neck. The Strapworks' bag strap replacement are ideal for that application.

Flat nylon webbing is the most popular choice for this strap because it has a "smooth feel" touch to it. When worn around the neck it will not cause any kind of discomfort as far as "digging" into your neck or a rough scratchy feeling.
Heavyweight or lightweight polypropylene is also common because it is great for the outdoors. It has excellent UV protection, and doesn't absorb water quickly giving it a high resistance to mildew and rot.
PLEASE NOTE: We recommend nylon webbing for "skin contact" bag strap replacement. Our nylon has a tight weave and a very smooth feel. So, for camera straps, where the strap is across the back of your neck, nylon would be more comfortable.
