While we recommend all of the first-aid kits on this list for various reasons, we have selected the Adventure Medical Kits Ultralight/Watertight .7 as our choice for the best overall first-aid kit — though, we’ve also used the Adventure Medical Kit .9 (that accommodates a slightly bigger group) and the Mountain Series kits as well, and liked those too.
Ultimately, the best first-aid kit to buy is the one that’s most likely to be useful when you need it.
