A wilderness first aid kit needs more than the basics from a home medicine cabinet. It should cover wound cleaning and closure, splinting support, blister care, and environmental injuries, sized to your group, trip length, and how far you’ll be from help. Below is a category-by-category checklist you can build from, plus a worksheet for adjusting it to your specific trip.
This article is a packing guide, not a treatment guide. For step-by-step instructions on cleaning wounds, building a splint, and deciding whether to stay put or evacuate, see our companion article, Wilderness First Aid: Wound Care, Splinting and Patient Stabilization.
Before You Pack: A Kit Is Not a Substitute for Training
Supplies only help if the person using them knows how to use them. A first aid kit does not replace hands-on training, and it does not replace calling for emergency help when someone has uncontrolled bleeding, a major injury, signs of heat stroke, or is unconscious or unresponsive. Pack the kit, but also learn the skills — see the training path in the companion article above.
The Core Checklist
This list combines items recommended by the American Red Cross for hiking, backpacking, and camping first aid kits, along with the general kit contents outlined by the Red Cross and MedlinePlus. Not every item applies to every trip — use the customization worksheet further down to trim or expand it.
Wound Cleaning and Closure
- Antiseptic wipes
- Sterile gauze pads (multiple sizes)
- Rolled gauze bandage
- Adhesive bandages (assorted sizes)
- Closure strips
- Adhesive cloth tape
- Antibiotic ointment packets
- Irrigation syringe (for flushing wounds with clean water)
- Non-latex disposable gloves
Splinting and Support
- SAM splint or finger splints
- Triangular cravat bandage (doubles as a sling)
- Elastic wrap bandage
- Roller bandage
A rigid, commercial-style splint packs smaller and is faster to apply than improvising one from sticks or trekking poles, which is why the Red Cross lists it as a standard hiking kit item. If you carry a tourniquet, treat it the same way as any advanced item on this list: it is only useful if you have been trained to apply it correctly, and misuse carries real risk. Learn tourniquet use in a hands-on course rather than from an article.
Blister and Skin Care
- Moleskin or blister-specific pads
- Hydrogel-based pads
- Liquid bandage
- Cotton-tipped swabs
Environmental and Pain Management
- Instant cold compress
- Emergency heat-reflecting blanket
- Sunburn/aloe relief gel
- Insect sting or anti-itch treatment
- Oral rehydration salts or electrolyte tablets
- Pain relief medication (adult and, if relevant, pediatric)
- Antihistamine
- Oral thermometer (non-mercury/non-glass)
Any medication in the kit should be something the people on your trip already know they can take safely. Do not pack, offer, or start anyone on a medication — including an EpiPen intended for someone else’s allergy — without that person’s own prescriber’s guidance.
Tools and Documentation
- Scissors or paramedic shears
- Tweezers
- Safety pins
- Hand sanitizer
- Biodegradable soap
- CPR mask (breathing barrier with one-way valve)
- Waterproof container to hold everything
- Notepad and waterproof pencil, for recording symptoms and timing if you need to relay information to rescuers
- Printed first aid manual or instruction card
Customize the Kit to the Trip: A Worksheet
The Red Cross specifically recommends tailoring a kit to the climate, group size, terrain, remoteness, and length of the trip, rather than packing one fixed list for every outing. Work through these questions before you pack:
- How many people, and does anyone have a known allergy or condition? This determines whether a personal item like an EpiPen needs to travel with the group — kept with that person, not as a shared supply.
- How many days, and how far from a trailhead or road? Longer, more remote trips need more wound care supplies and a larger blister and skin care allotment.
- What’s the climate and season? Hot, dry trips lean on rehydration and sun or heat items; cold or wet trips lean on the emergency blanket and skin protection.
- What’s the terrain? Rougher terrain raises the odds of a sprain or fracture, which is where splinting supplies matter most.
- Will you have cell or satellite communication? This affects how self-sufficient the kit needs to be, since it changes how long you may be managing an injury before help arrives.

Maintaining the Kit
A kit that sits unused for a year is not a reliable kit. Check it before every trip and again on a set schedule at home. Confirm expiration dates on ointments, medications, and any sterile packaging, and replace anything used, opened, or expired. Restock immediately after a trip rather than waiting until you’re packing for the next one.
Where a Kit Fits Into Your Broader Preparedness Plan
A wilderness first aid kit is one part of a larger preparedness setup. If you’re building this out as part of a full bug out bag, review what else belongs alongside it. For supplies and tools beyond first aid, see our survival gear coverage, and for the broader picture of readiness at home, see home preparedness.
Evidence Limits
The item lists above are drawn from published American Red Cross hiking, camping, and general first aid kit guidance and the MedlinePlus first aid kit overview. They are general recommendations, not a guarantee that any specific kit is adequate for your trip, your medical history, or a specific emergency. Pregnant people, young children, older adults, and anyone managing a chronic condition or taking regular medication should talk with their own healthcare provider about what to add to a kit before relying on it.
Frequently Asked Questions
How is a wilderness first aid kit different from a basic home kit?
A wilderness kit leans more heavily on splinting support, blister care, and environmental injury items like cooling and warming supplies, because help may be an hour or more away instead of a short drive. A basic home kit can be lighter on these categories.
Do I need a tourniquet in my kit?
Some published camping kit checklists include one, but a tourniquet is only useful if you’ve had hands-on training in applying it. Carrying one without that training does not make you safer.
How often should I check my kit?
Check it before every trip, and set a recurring reminder to review it at home even between trips, so expired or used items get replaced before you need them.
Should everyone in my group carry a full kit?
Group trips commonly split kit contents between multiple bags so the group isn’t relying on a single kit if someone gets separated. At minimum, anyone with a personal medical need, like an EpiPen, should carry their own.
