I tell people that if you are willing to wear one all the time it might do you some good. i.e. you turn a "Critical Survival Item" into Wearable Fashion. If not it's just 3m of Cord and if you simply carry the cord it is far easier and quicker to employ.

Same 3m (10Feet) of Cord


If you place some other Critical Survival Items on/in the Bracket it would be more useful, but only if the items themselves are worth carrying.
