I have both CATs and SOF Ts and Feel that about the SOF Ts are superior in design and ease of use. I am going to get a SWAT T to see how it works, it looks like it is a big rubber band. It may be good for an arm wound but i am not sure if it would work on a leg.
Someone with more experience is welcome to make corrections.
It's just like a large bike inner tube that has been cut open.
It works fine on either a leg or an arm.It gets really tight.
It can be a bit tricky to apply one handed on your own arm though but it can be done with enough practice.
The CAT is probably better and faster for a one handed self applied application.

You can use it as an arm sling or even just to old an ice pack in place as well.
Many uses for such a compact product.
