I bought a couple of these for use when hiking. Twisting an ankle or injuring a wrist/finger/elbow from falling/tripping are probably more likely a concern when out. Being able to splint up an injury on the spot is a nice option to have vs finagling some sticks to fashion a splint.
Its very lightweight tho bulkyish. I feel the size weight vs different splinting applications is a win which has me carrying this item when out on hikes. I have a few in my home first aid bag as well.
