I'm an ex wilderness EMT and current medical student and this is the kit I always have on me. If I'm out with the family or a large group I bring something more, but going solo or with competent friends this is it. I will even throw it in the pack around town for those bike vs cab road rashes or dealing with the random subway first responder situation.
It's a great little package with room for extras. I added a pair of small trauma shears, a couple single use superglue tubes, a very small spray bottle of hand sanitizer and another of deet, an extra set of gloves a couple sugar and re-hydration packets, a couple packets of sting-ease, two yards of duct tape and a mini bic lighter. There is more than enough room, and the whole thing weighs in at under 8 oz. Not bad for a kit that can fit in my pocket and handle any common situation.
