I guess I am just not a fan of survival bracelets. If I want cordage, I include it in my kit (and no question, cordage is highly useful).

I do worry about a loop of very strong cordage around my wrist where it could catch in machinery, etc., or get caught on something during a fall (especially a climbing situation). I generally remove my wedding band when climbing - they areknown for causing deglovement injuries, which are rather nasty.
