NANUK 903 Waterproof First Aid Box Empty – Durable, Medical First Aid Organizer Case, IP67-Rated, Dustproof, Impact-Resistant, and Floats (7.4" x 4.9" x 3.1") – Red

I could not be more satisfied with this box (and that's not something I usually say with purchases these days.) Both the box, buckles, and the handle are made of thick plastic, that have a very quality, sturdy feel to them. Holding this box, you get the impression it will last longer than you will. The locking buckles are equally up to the task. It has a "burp" valve, allowing built-up pressure to exhaust out, while also not allowing water to come in. It has a large o-ring seal about the main opening, making a water-tight seal. I go kayaking out on the ocean (often alone, when I don't have a teammate to come along), and occasionally kayak-camp. This is my main first aid kit when kayaking. (Everything inside I stocked myself. I've never found a pre-made first aid kit I was happy with.) I haven't been able to come up with any cons for this product. I've owned it for about 8 months now, and taken it out on the water with me several times. (Although, I've been lucky enough to not have to pull it out and use it yet.) However, if I notice any flaws, I will update my review. Some little tips to help make this case even more useful: 1) Use magnets to attach things to the inside of the lid. For example: I ordered some small button-sized rare-earth magnets, and used Gorilla Tape to tape them to the inside of the lid (completely surrounded by tape on all sides, so if I accidentally splash water into the case, the magnets won't rust from the saltwater). Then I was able to stick my medic shears to the magnets. So when I flip the box open, my shears are right there and ready to grab in an emergency. I also used this method to attach a few hemostat pliers (they look like scissors, but are really little pliers that can be used to clamp squirting arteries/veins, etc.). 2) I recommend adding some reflective tape to all sides of the outside of the box. That way in an emergency at night, it is easier to find when shining a flashlight around. Also, since it floats, if it ever gets dumped over the side of your boat in the dark, shining a light around will make it easier to spot. (Although, everything on your kayak should be lashed down.) All in all, I could not be happier with this purchase. I can't say enough how much it looks like this company put a lot of time and effort into making a quality product (rarely said words these days). I am glad I bought this product, not just for this purchase, but because it gave me the confidence to come back and purchase more for my other first aid kits I keep in the house, car, work, etc. If you're looking for things to stock it with (while this is all subject to what environment you're going to be in and your medical experience), here are some general recommendations (all can be found on Amazon): I strongly recommend the Israeli battle bandage. Hands down the best all-around bandage on the planet.; it can handle almost any kind of wound in a pinch. Have a few of these in all of your first aid kits. They are very capable of saving a life. Quality, pre-made windlass tourniquets Clotting powder Shapeable splint Silicone spray-on bandage Medic shears (to cut away clothing when trying to find the bleed) A collection of many different sized/shaped quality bandages (Band-Aids), with a good supply of waterproof bandages if you're going to be around water or rain. Don't cheap out on bandages either. You don't want to find that that cheap bandage you bought doesn't actually stick and keeps falling off when you're out in the middle of nowhere. Triangle sling (large piece of triangular cloth that can be used as an arm sling, among other things) If you have extra space to fill, gauze can come in real handy, but takes up a fair bit of space in a kit Past that, you need to consider the environment you'll use this in, and the people that are most likely going to need it, and stock it for them (like extra prescription medications, etc.)

This is a great box for first aid supplies. I'm an archaeologist, and usually the Health and Safety officer for our projects. I always carry a wide variety of first aid supplies for myself and my crew. Frequently we are in very remote back country and having this kit gives us all piece of mind. All the other kits I was looking at were either too big or too small. This is just about the perfect size. I will confess that it is a little larger than I wanted, and being a hard case makes it slightly harder to pack. However, it fits in my back pack with my other equipment and I make it work. Safety is worth it. Waterproof and very well made.

I got the 909, its an excellent box, but it was too small to fit all my 1st aid crap in it. I returned the 909 and ordered the 910 which is larger. These 1st aid kit boxes can be turned into generation boxes from parents to great grandchildren.

This fits absolutely to a tee for the new 2026 Honda Passport cargo space. We needed something that could hold all emergency supplies on the road and wanted a one-time buy for life. This case hits the home-run. So well-built and top-notch quality its literally a thing of beauty. You get what you pay for on this one. Just pull the trigger, you won't be sorry you did! Rarely ever find a true 5/5 product, but here it is!

Good - solid - sturdy first aid box. I thought it would be too little but it actually is a good size. I use this on my boat for my first aid supplies. My goal is to keep my supplies dry vs a plastic bag or container.

This box is very solid and well-made! I'm quite pleased with the purchase. We used it to store critical trauma supplies in a very isolated ag shelter. The lock holes are reinforced and solid if you need to release control of it at any time while traveling. There is ample space (see details in the listing) inside for several supplies. We have a Stop the Bleed Intermediate in there with extra bandages, but honestly, you could fit two of those kits and still have a little room on the top. Since this is a rural, outdoor, unpowered ag shelter I am very interested to see how this holds up. It is mostly protected from direct wind, rain, etc... but only time will tell. If I learn more in the coming months and years, Ill update the review. However at this time, VERY VERY PROMISING.

The build quality of the case is fantastic and will work for most light to medium duty emergency med kit tasks (home, workshop, small car/field kit, etc) especially since it's waterproof. However, there is one part of the case that I don't like - the latches. They require a tab to be pressed downward as you lift the lower portion of the latch and then the upper portion of the latch frequently has to be pulled away from the box in order to open it. This design choice is, I am assuming, made to keep the box from accidentally opening when it's being jostled about if you're in the field with it. The problem, though, is that in an actual emergency situation where seconds count and people often aren't thinking clearly, it makes it more difficult to *use* the case and therefore can be considered a design failure and safety issue.

Nanuk makes incredible first aid hard cases. They are pretty solid and can survive being thrown around. And unlike my prior case which was a fabric, it won't ever mold. My previous one did mold. I've even had a bottle of rubbing alcohol leak and it stayed self contained within the carrying case. I've bought three to date with different purposes. The 903 was the first one I purchased and I'm using that as a mini first aid kit to keep in my car. It is insanely small, but can still carry basic emergency supplies like bleed stop, array of bandages, burn creams, antibiotic ointment, ect. 5 out of 5! The second first aid kit was the 909. I initially purchased this for our house and to take in our RV when we are camping. It could only hold a few of our first aid items, so I abandoned the idea and am now using it to hold diabetic supplies like syringes, continuous glucose monitor, and lancet. 3 out of 5. I ended up settling on the 920 for house/camping first aid kit. It is huge and can hold a lot of supplies including large bottles of wound care. 5 out of 5. I would say if you want a small compact first aid kit for a car go with the 903. If you want a more complete kit, I would purchase the 920. I wouldnt recommend the 909, because of the weird sizing and the fact it would be too small for most people's first aid kits not being able to fit full size bottles or larger items.
