Very easy to put on and tighten as well as quickly ...
I use these for Blood Flow Restriction training and they do the job. Very easy to put on and tighten as well as quickly releasing with a tap (which is a major plus when you are so pumped out!). I can't say how they are in a first aid situation since I did not use them for that, but they don't seem to have any issues tightening and holding well enough to restrict blood flow. I also use them twice a week so I will update if any durability issues occur.
