In my constant reevaluation of my backpacking kit I often look through my first aid kit and think what items I could make do without and improvise from something else.
One of those is an elastic fracture/sprain bandage with velcro that I always carry but felt that I could make do with another piece of gear or two to create a splint. Never pulled the trigger on that though and now I don't regret it.
Last weekend I slipped on a granite outcrop taking a photo and naturally put my arm out to break my fall. Knew immediately I had done something bad to my wrist. The pain was enough to cause some nausea. I know I could have rigged something up even through a fog of pain, but I was definitely appreciative of the ease of using the wrap one handed to immobilize what ended up being a fractured wrist. A quick wrap, some water a snack and pain meds, and the walk out was much improved and faster. I even stopped for a couple more photos once things stabilized!
I'll keep my first aid kit the way it is...
