2" Webbing: 2-2.5 yards

2" "Loop Loc": 1

Something to cut webbing and fabric/leather
I used Tubular Nylon Webbing, I would recommend against that, because it is significantly bulkier and heavier. I'd suggest either polypropylene, or if that's not available you could use flat nylon. Really you could use anything. This could be done with seat belt webbing and a buckle from an old car and look much cooler than mine.
You could also use a variety of other options on the buckles, I just wanted something that could be adjusted and this stuff was handy. Also for mine I used 1/4" shock cord, I would recommend using lighter weight shock cord (actually the shock cord is optional).
All of these materials can be had from a variety of retailers, some of my favorites online are: Outdoor Wilderness Fabrics
and The Rainshed
