First off let me say that I am a ICU RN who gets lots of Traumas from the field...
I am also a Wilderness EMT level trained for remote areas...
So which do you want? Neither....yep DO NOT BUY EITHER...
And here is why...
1) I have personally stopped massive bleeding with direct pressure...that is the safest option
2) You need to be able to clean the wound not trap crap in there.
3) If you really have a massive bleed issue on your hands the person will more than likely be dead before you can get them to help...but if you do get them to help don't make the Dr take more time to dig the crap out of the wound.
4) The stuff was made for military field use where the person will be taken quickly to a top rate trauma bay....you will more than likely take the patient to a small remote medical clinic.
So what should you spend your money on...
Kerlex (rolled bandage) which you can stuff over a bleed and apply direct pressure...
Get a 20 or 60ml syringe so you can flush out the crap from a wound.
Gloves to keep the blood off of you....lots of gloves and check your kit with the change of seasons as the gloves will go bad (break easy)
Then go take a Wilderness First Aid course....I learned tons about remote aid even though I was well experienced in urban med.
Remember it is all about what you are most likely to encounter...
Vehicle crash..
Body part smashed..
campfire/cooking burn...
hand slice with cooking...
stomach aches for bad food or poor hygiene...
Stop the bleeding with direct pressure, clean the wound with water clean enough to drink, bandage with wound and repeat....this will work on all but the stomach...that is all about letting the bad stuff out (nausea or poop) and hydration.
In a bug out bag (where you have to leave your rig) you are more concerned with shelter, water on hand and the ability to filter more, signal, food and the ability to cook more....
Garbage bags (contractor 3mil ones) x5
100ft of real paracord
Adventure Medical Kits pocket survival kit
Tablet stove with a pack of spare tablets
Sierra cup
Oily cup on bottom of naglene bottle (in bottle pack some drink or food)
snack bars
good fixed blade knife
emerg bivy bag
water filter setup
poncho
wool beanie
first aid kit
and a bit more I can't think of...maybe I should just to out to the rig and get my bag
But most important it has to be within reach of the driver so if your rig rolls or catches fire you can grab and go...
