This webbing can generally be refned into a form of fabric. This is fabric is naturally is flexable, soft and extremely tough, capable of talking and neutralizing most peircing damage.
This does not specifically apply to basic impact damage. this becomes a means as an outer shell for multiple types of armour, including some plate armour or carriages.
The fabric has limited heat resistance, capable of dispersing more heat than most fabric, but it cannot hold that heat for a long time. Once it reaches it's breaking point, it will pretty much turn to jell and will rip apart quicker than paper and even wash away easily.
