It's great stuff, great for sprains and strains . . . especially around joints, as it bonds onto itself and keeps the tension for over much longer period of time then your standard heavy crape bandages.
I don't use them in My Event Kits for cost reasons, but I do have about 5 or so for personal use, and do recommend them to Participants of Rider Down and Remote Area First Aid Training Course I do, as once you apply them you generally don't need to reapply them.
Another item I recommend to those who visit Off the Beaten Tracks and remote travel is the Combat Tourniquet - https://www.ebay.com.au/itm/Combat-T...frcectupt=true
Quick and easy to apply to stop major life threatening bleeds in an Emergency.
As I do a lot of Charity Motorcycle Rides, I carry 4 in my Event Kit on the bike . . . nasty what a guard rail can do.
I also always carry a Roll of Cling Wrap / Glad Wrap as part of my Burns Kit in my truck as well. Very good for dressing burns - sterile, non stick, transparent (to visually monitor the injury) and quick and easy to apply.
