DYNAM engineers are more dynamic than that (hah, pun!) so we took a super nice cloth; 100% cotton with a damask slant weave, hired someone who knows how to sew garments, and crafted something beautiful. Why these specific things, you ask?
The damask slant weave is super important, it locks onto itself when you wrap it. This means you can really fine tune just how tight you need it and they get TIGHT so be careful. Then to tie it off, Military Type-I paracord makes sure you aren't hosting a garage sale in the middle of a WOD, that's supposed to be for after you're done.
