These emergency trauma bandages are very safe and secure. I got these for just in case purposes and wasnt going to try it out until i had to but luckily the company sent me two so i could try one and keep one. These are very soft and loose fitting. They are secure enough though to protect a serious would or a minor one. These could also be used as a wrap when support is needed in a pinch. I am very impressed with this product and would consider purchasing again. I would also recommend to others. I received this product for free in exchange for my complete and honest review.
