THE 8 ESSENTIAL KITS™
The First Aid Kit — Pack for the Injuries You'll Actually Treat
A wilderness first aid kit isn't a department-store box of band-aids. It's organized around the four most common injury categories you actually see in the backcountry — bleeding, breaks and sprains, burns and blisters, and bites and stings. Build it that way and the kit gets short, useful, and light.

The 4 B's of Wilderness Medicine — How the Kit Is Organized
Before you buy a single bandage, frame the question correctly: what are the most common injuries you'll actually treat in the wild? Pack for those, and skip the rest. The 4 B's of Wilderness Medicine is my framework for that — four injury categories that account for almost every field-treatable problem outside of cardiac and drowning emergencies (which are evacuation problems, not kit problems).
The 4 B's of Wilderness Medicine
Bleeding — the time-critical category. A massive hemorrhage can kill in minutes. Everything else gives you longer.
Breaks, Sprains, and Strains — orthopedic injuries from falls, twists, and overuse. Less time-critical, but they immobilize you.
Burns and Blisters — skin damage from fire, friction, and exposure. Small surface area in the field, but they get infected fast if you ignore them.
Bites and Stings — the category most people overpack for and least understand. The honest answer is car keys and a phone, plus your prescribed meds.
Build a sub-kit for each of the 4 B's. That gives you a kit you can actually find what you need in under pressure, instead of dumping a tackle box of supplies on a casualty and hoping. A wilderness first aid kit also leans on the rest of your gear — your shelter, your fire, your insulation — to manage shock and hypothermia. Improvising medical care from non-medical gear is fine as a supplement; it's a poor substitute for carrying the right purpose-built item.
"We don't improvise on purpose."

Bleeding — The Time-Critical Category
Severe arterial or junctional bleeding can drop blood pressure to a fatal level in three to five minutes. That's why the bleeding sub-kit is built for speed of access, not just contents. Whatever you carry, you need to be able to find and deploy it without thinking and without untangling it from the rest of your gear.
The two interventions that matter at the kit level are the tourniquet (for limb hemorrhage you can isolate) and the wound-packing-plus-pressure-dressing combo (for junctional wounds where a tourniquet won't work — neck, shoulder, groin, armpit). Carry both. Carry a backup tourniquet too, because tourniquets fail and the backup is not optional in a real bleed.
Bleeding sub-kit — what goes in
Primary tourniquet: Staged where you can reach it one-handed in under five seconds. Dominant-side hip, chest rig, or shoulder strap — never sealed inside the IFAK pouch.
Backup tourniquet: Inside the IFAK. If the primary fails or the bleed needs two, you have a second one ready.
Wound packing gauze: For junctional wounds that can't take a tourniquet. Pack it deep, hard, and to the source of the bleed.
Emergency Trauma Dressing (ETD): Goes on top of the packed gauze as a pressure dressing. Holds the packing in and adds compression.
Trauma shears: To expose the wound fast through clothing. You can't treat what you can't see.
Emergency blanket: Hypovolemic shock and hypothermia ride along with major blood loss. Shelter and fire are your first line; a Mylar blanket is the kit-level backup.
The container that holds this matters. The GB2 IFAK was designed around exactly this layout: the standard CAT (Combat Application Tourniquet) inside is meant to be your backup, not your primary. Your primary CAT lives outside the pouch on a tourniquet keeper or readily accessible carrier where you can grab it one-handed.
The NAR Wound Packing Gauze and the 4" Emergency Trauma Dressing ship inside the kit. NAR Trauma Shears and a Mylar Emergency Blanket are the recommended add-ons.
The GB2 Custom IFAK Pouch was built for this system: the IFAK and emergency blanket fit inside, the trauma shears get a dedicated holder, and there are external tourniquet keepers on the outside so you can stage your primary CAT however your rig demands.
Breaks, Sprains, and Strains — The Mobility Killers
Orthopedic injuries are usually less time-sensitive than a major bleed (compound fractures with active bleeding being the obvious exception — treat the bleed first, then the break). What they do is take you off your feet, which in the backcountry means a self-evac can become a carry-out.
The kit answer is dedicated immobilization gear, not improvised splints from sticks and cordage. You can improvise; you'd rather not. A SAM Splint II rolls flat against the IFAK, weighs almost nothing, and conforms to ankle, wrist, forearm, or even cervical spine in a pinch. Two 6" elastic wrap bandages hold the splint in place and double for sprain compression.
Carry at least two triangular bandages. They are the most versatile piece in the kit — sling for a shoulder injury, swathe for an arm to the chest, secure a head wound, or build a pressure dressing in a pinch. If you only had three things in your first aid kit, two triangular bandages would be one of them.
Burns and Blisters — Small Surface Area, Big Consequences
Wilderness burns are usually small and contact-based — a hand on a hot pot bail, a forearm against a Dutch oven, an arm stamping out an errant flare-up at the fire ring. Surface area is small, but a burn the size of a quarter that gets infected on day three of a five-day trip is now a problem.
The right answer is hydrogel burn dressing, not improvised gauze. The BurnTec 4x4 Dressing is FDA-cleared, sterile, cools the burn on contact, and stays in place under a triangular bandage or wrap. Carry one.
Blisters are the day-to-day version of the same category and they ground you faster than a real burn. Prevention is the actual answer — broken-in boots, sock liners, and a willingness to stop and tape a hot spot the second you feel one. Once you've got a real blister, drain it cleanly with a sterilized needle and dress it; don't unroof it unless it's already torn.
Bites and Stings — The Honest Answer
This is the category the gear industry has done the worst job with. Snake-bite kits sold in retail packs do not work. Suction extractors don't extract enough venom to matter. The cut-and-suck method is twentieth-century mythology that does more tissue damage than the snake did.
"Your 'snakebite kit' is your car keys and cell phone and getting to an emergency room as quickly as possible."
Joshua Enyart · First Aid in the Wilderness
For venomous snakebite, the field response is to stay calm, immobilize the bitten limb at or below heart level, mark the leading edge of swelling with a pen and time-stamp it (so the ER can track progression), and self-evac to definitive care. Do not apply a tourniquet. Do not cut. Do not ice. Do not try to suck out venom.
For insect stings, the kit answer depends on personal medical history. If you're not allergic, a sting is a discomfort, not a kit problem. If you are allergic, you carry exactly what your doctor prescribed — usually an epinephrine auto-injector and antihistamines — and you carry a second one, because anaphylaxis can rebound after the first dose wears off.
Same logic for any pre-existing condition: asthma inhaler, insulin, nitroglycerin, blood-pressure medication, mental-health prescriptions. Your kit isn't complete until your prescriptions are in it, in the dose and form your doctor specified, packed somewhere waterproof.
Carry It For You — Not Just Others
One thing students miss: most of what you carry in your IFAK is for treating yourself. If you're the casualty, you may have only seconds before you lose consciousness or motor control. The CAT on your dominant-side hip needs to be one-handed-deployable because your other hand may be holding pressure on the wound.
The same goes for the people around you. Someone coming to your aid may have more training than you do, but they can only use what's in your kit and where they can find it. A standardized layout — primary CAT staged, IFAK contents in a known order — is what lets a trained partner work on you without slowing down to figure out what you packed where.
"The resources you carry are to be used on you primarily."

Training + Experience = Confidence™
The kit is the floor. The skill is the ceiling. A loaded IFAK doesn't treat anyone — you do. The single highest-leverage upgrade to your kit isn't another tourniquet or a fancier pouch; it's a real Wilderness First Aid (WFA) certification so you know how to use what you carry. Build the kit, then put the reps in until you can apply a tourniquet, pack a wound, and splint a fracture without thinking.
