What It’s Like to Use
What stands out most about the Ultralight/Watertight .7 is how much it manages to fit into such a small, light package. Testers who’ve taken it hiking and snowshoeing through rain, snow, and sun report that the two-stage waterproofing genuinely works — the kit stayed dry even when stashed at the bottom of a pack or briefly set down in snow.
The contents lean toward common trail injuries rather than serious trauma: gauze, non-adherent dressings, multiple sizes of moleskin for blisters, antiseptic wipes, butterfly bandages, and a small roll of duct tape for gear repairs. It’s well-suited for the scrapes, blisters, and minor aches that come up most often on the trail, but it’s not designed to handle a major injury on its own.
One practical note from real-world use: the inner DryFlex bag needs to be zipped closed carefully, as it can come undone if you’re not paying attention. It’s a minor inconvenience, but worth knowing before you rely on it in wet conditions.
Who Should (and Shouldn’t) Buy This Kit
Buy this if: You’re a day hiker, ultralight backpacker, or multi-sport athlete who wants a genuinely waterproof, no-frills first aid kit that won’t weigh you down. It’s also a solid base kit to expand with your own supplies.
Consider something else if: You’re leading group trips, heading into the deep backcountry for a week or more, or want a kit equipped to handle more serious trauma. In those cases, a larger kit like the AMK Mountain Series or My Medic MyFAK will serve you better.
