What Should Be in a Hiking First Aid Kit?

A Paramedic’s Guide to Packing Smarter for the Trail

By Brandon Byers · Founder, MED KIT PRO™ · 20+ Years as a Paramedic/Firefighter

Miles from the trailhead, something goes wrong. It doesn’t have to be dramatic — a bad step, a deep cut, a sting that triggers a reaction. In that moment, what you’re carrying matters.

After more than 20 years as a paramedic/firefighter, I’ve learned that the best hiking first aid kit isn’t the biggest one. The right first aid kit depends on where you’re going, how long you’ll be out, and how far you are from help — and that’s exactly what this guide will help you figure out.

Rather than simply handing you a checklist, I’ll walk you through how I actually think about preparing for a hike — so you can make informed decisions for your own adventures.

 

Think Before You Pack

When I pack for a hike, I don’t start by asking, “What can I fit into this pouch?”

I start by asking, “What situations am I preparing for on this hike?”

Not every hike requires the same level of preparation. A short trail on a popular route presents different challenges than an all-day hike where help may be hours away. Before adding a single supply to your kit, think about where you’re going, who you’re hiking with, and how long it might take to get help if someone is injured.

Every item in my kit has a job. If I can’t explain why I’m carrying something, I take another look at whether it belongs. Just as important, every item has a consistent place so I can find it quickly under stress instead of digging through a pile of supplies when every second counts. That mindset keeps my kit practical without filling it with supplies I’m unlikely to use.

 

BEFORE YOU PACK, ASK YOURSELF…

Question

Why It Matters

How long will I be on the trail?

Longer hikes often require additional supplies, food, and water.

How far am I from medical care?

The farther you are from help, the more self-sufficient you’ll need to be.

Am I hiking alone or with others?

Larger groups usually require additional supplies.

   

What weather and terrain should I expect?

Conditions influence what equipment and first aid supplies make sense to carry.

Does anyone have allergies or medical conditions?

Bring medications and supplies that fit your group’s specific needs.

BRANDON’S PERSPECTIVE:

When I build a hiking first aid kit, I don’t measure it by how many supplies it contains. I measure it by whether the supplies are well chosen, well organized, and ready when I need them. That’s the philosophy I used when designing the SOLO MED KIT™, and it’s still the standard I apply every time I build or evaluate a hiking first aid kit.

 

Bleeding & Bandaging

If someone is bleeding, controlling that bleeding becomes the first priority.

When I evaluate a bleeding injury, I’m not thinking about products first — I’m thinking about priorities. Can I control the bleeding? Once that’s accomplished, I can focus on cleaning, protecting, and monitoring the wound. The supplies I carry simply support that process.

For most injuries, that starts with direct pressure using clean gauze or another appropriate dressing. Once bleeding is under control, the right bandage helps protect the wound while you decide whether it’s safe to continue hiking or time to head back.

For hikes where professional medical care may be delayed, I also carry BleedStop™. It’s lightweight, takes up very little room, and provides another option for helping control external bleeding when direct pressure alone may be difficult or when you’re a long way from professional medical care. It isn’t a replacement for direct pressure, but it gives me another tool when I need it most.

RECOMMENDED SUPPLIES

  • Sterile gauze pads 2×2 and 3×3
  • Gauze roll 3″
  • Self-adhering compression wrap
  • Elastic bandage
  • Medical tape (cloth)
  • A variety of adhesive bandages
  • BleedStop™ — particularly for more remote hikes

TRAIL TIP 🥾

Keep your bleeding and bandaging supplies together and easy to reach. When every second counts, organization matters.

 

Wound Cleaning & Preparation

Once bleeding is controlled, the next priority is reducing the risk of infection.

Even a small scrape can collect dirt, gravel, or plant debris on the trail. Taking a few extra minutes to clean a wound before covering it helps reduce the chance of trapping contaminants beneath the dressing.

RECOMMENDED SUPPLIES

  • Sterile saline eyewash 20mL
  • BZK antiseptic wipes
  • Povidone-iodine prep pads
  • Alcohol prep pads
  • Hand sanitizer packets
  • Wet wipes

 

Skin Care: Burns, Bites & Blisters

Many trail problems are easier to prevent than they are to treat.

Blisters are a great example. They usually begin as friction long before the skin breaks. If you recognize a hot spot early and protect it, you may prevent a blister from developing in the first place. Sun exposure, insect bites, minor burns, and skin irritation are all common trail problems that are easier to manage when you have a few well-chosen supplies on hand.

RECOMMENDED SUPPLIES

  • Burn gel packets
  • Hydrocortisone 1% packets
  • Triple antibiotic ointment packets
  • Sting & bite pads
  • Sunscreen SPF 30
  • KT Tape® — blister prevention

BRANDON’S PICK:  KT TAPE®

Most people think of KT Tape® for supporting sore muscles or joints. I carry it for another reason. If I notice a hot spot starting to develop on my heel or foot, I’d rather protect it early than wait for it to become a blister. A minute of prevention can save the rest of your hike.

 

Medications to Consider

The goal isn’t to carry a medication for every possible problem. It’s to carry the right ones for the problems hikers actually encounter.

After two decades responding to calls, I’ve noticed that the emergencies people least expect on the trail aren’t always traumatic ones. A GI issue, an allergic reaction, unexpected nausea — these are the things that end hikes early or turn a manageable situation into a serious one. That’s the thinking behind the five medication categories in every MED KIT PRO™ kit.

Pain & Fever covers the obvious — aches, minor injuries, fever. Allergy & Antihistamine addresses reactions that can escalate faster than people expect outdoors. GI & Stomach because digestive issues on the trail are more common and more debilitating than most hikers plan for. Cold & Mucus for respiratory symptoms that worsen with exertion or altitude. And Motion & Nausea — the one that surprises people most. Winding mountain roads, altitude, and heat can trigger nausea fast, and Meclizine weighs almost nothing.

The FAMILY MED KIT™ carries the same five categories with increased quantities — because the likelihood of someone in your group needing something goes up with every person you add.

RECOMMENDED SUPPLIES

  • Pain reliever (acetaminophen or ibuprofen)
  • Aspirin (when appropriate)
  • Antihistamine (diphenhydramine or loratadine)
  • Anti-diarrheal medication
  • Antacid
  • Meclizine (for motion or altitude-related nausea)

TRAIL TIP 🥾

Only carry medications you understand and know how to use. Read the label, be aware of possible side effects, and consider any allergies or medical conditions before taking them.

 

Tools & Emergency Gear

First aid supplies usually get most of the attention, but the tools you pack can be just as important — and sometimes a small, lightweight item makes the biggest difference.

Take the emergency whistle. It weighs almost nothing, but it carries farther than your voice ever will if you need to signal for help. The penlight isn’t just for checking pupils — it’s useful any time visibility is limited and your hands need to be free. The Mylar thermal blanket folds down to the size of a deck of cards and can be critical if someone goes into shock or conditions change faster than expected. And the water purification packets are there because hydration emergencies sneak up on people — especially at elevation.

Everything in the Tools Zone has a specific job. If I can’t explain why it’s there, it doesn’t make the kit.

For those heading into more remote environments, the PRO MED KIT™ carries a meaningful step up in capability — adding a C-A-T® tourniquet, QuikClot®, Israeli compression bandage, chest seal, light stick, paracord, and a nasopharyngeal airway. These aren’t upgrades for their own sake. They’re tools for situations where you may be the most capable person on scene for a while.

RECOMMENDED SUPPLIES

  • Trauma shears
  • Tweezers
  • Nitrile exam gloves (2 pairs)
  • Emergency whistle
  • Penlight
  • Mylar thermal blanket 52″x84″
  • Liquid I.V.® hydration packets
  • P&G Purifier of Water® packets

 

Practice Before You Need It

As an Eagle Scout, a paramedic/firefighter, and a wildland firefighter, I’ve spent most of my life in environments where preparation isn’t a suggestion — it’s the difference between a good outcome and a bad one.

One of the biggest mistakes I see isn’t carrying the wrong supplies. It’s carrying supplies you’ve never touched before the moment you need them.

Open your kit at home. Find everything. Practice applying a compression wrap. Put KT Tape® on a hot spot before you’re on the trail trying to figure it out for the first time. Know where your whistle is without looking.

Confidence comes from familiarity, not just ownership.

Check Your Kit Before Every Hiking Season

Even the best first aid kit needs occasional attention. Before your first hike of the season, take a few minutes to:

  • Replace expired medications
  • Restock any supplies you’ve used
  • Check packages for damage or moisture
  • Confirm you know where each item is located
  • Adjust your kit for the type of hiking you’ll be doing this season

A well-maintained kit is far more useful than one that’s been sitting untouched in a closet.

Choosing the Right Hiking First Aid Kit

If there’s one thing I hope you take away from this guide, it’s this: a good hiking first aid kit isn’t about carrying the most supplies. It’s about carrying the right supplies for the adventure you’re planning.

The right kit isn’t necessarily the largest one — it’s the one that matches your hike and gives you confidence that you’re prepared for the problems you’re most likely to encounter.

Frequently Asked Questions

What should every hiking first aid kit include?

A hiking first aid kit should include supplies to control bleeding, clean wounds, protect injuries, and manage common trail problems like blisters, insect bites, and sun exposure. You’ll also want basic medications and a few emergency tools — at minimum, nitrile gloves, an emergency whistle, and a thermal blanket.

How big should a hiking first aid kit be?

Choose a kit based on your hike, not just its size. Day hikes often require a compact kit, while remote or multi-day trips may justify carrying additional supplies. The right size is the one that matches the environment and the level of risk you’re preparing for.

Should I carry BleedStop™ while hiking?

For hikes where professional medical care may be delayed, BleedStop™ is worth considering as part of a hiking first aid kit. It is lightweight, takes up very little space, and provides an additional bleeding-control option alongside direct pressure and appropriate dressings—and it’s lightweight enough that there’s little reason not to carry it on more remote trails.

What’s the difference between a hiking first aid kit and a backpacking first aid kit?

Backpacking kits are often designed for longer trips, greater distances from medical care, and overnight travel. Many hiking kits focus on common injuries encountered during day hikes. Regardless of the trip type, the core principle is the same: your supplies should match your environment and the level of risk you’re preparing for.

Can’t I just buy a pre-made first aid kit at a drugstore?

You can—and having a pre-made first aid kit is better than having no kit at all. However, many basic drugstore first aid kits focus primarily on adhesive bandages and common wound-care supplies. A hiking first aid kit should be selected for the trail, the length of the hike, the number of people in your group, and how far you may be from professional medical care.

A Paramedic-Built first aid kit adds greater intentionality. Every MED KIT PRO™ kit includes BleedStop™ and dedicated bleeding-control supplies, along with medications, emergency tools, and clearly labeled Zones so you can find what you need fast when every second counts.

 

Brandon’s Final Thoughts 

The best day on the trail is the one where your first aid kit stays zipped up in your pack. But if the unexpected happens, you’ll be glad you spent a little time preparing before you left the trailhead. My hope isn’t that you carry more gear — it’s that you understand why you’re carrying it, know how to use it, and feel confident exploring the outdoors.
