This is the sort of webbing that belts and rucksack straps are made of. With the buckles listed and a little imagination a lot of simple bits of kit can be made or adapted.
It comes in widths: 19mm, 25mm, 40mm and 50mm (we are sorry but we can't seem to get 30mm any more).
Prices are per metre or you can buy a 50m roll.. If you want several lengths - please specify this in the comments box as you check out - or send an accompanying email.
Seal with heat if you need to cut it (a match or lighter will do, though a hot-knife makes a much better job).
NB. Polypropylene tape is not suitable for climbing use or for slack lining. It stretches too much and is liable to snap!
