First Aid Kits for Wilderness Hiking and Backpacking

The best first aid kit is one you know how to use.  It is important to understand its contents and which items can have multiple uses. It is also important recognize your first aid kit’s limitations and thus learn how to use your environment to provide emergency resources. For example, I do not carry a Sam Splint on backpacking trips because I know there are many ways to improvise immobilizing a joint using resources from the environment (i.e. trees and branches)  

I highly recommend taking a Wilderness First Aid (WFA) course.  WFA skills are important to anyone tackling local trails or planning multi-day backpacking adventures in the High Peaks. WFA will teach you the essential skills for remote first aid, help you understand decision points for care when an ambulance or ranger is several hours or days away and how to use materials in your environment to administer critical care.

Every first aid kit should have a base set of items to address basic first aid which includes wound care, medication and various “tools”. We will classify these items as Essential. Vertical Aid by Seth C. Hawkins goes over 9 considerations when building a first aid kit:

  1. Medical Knowledge of Group
  2. Size of Group 
  3. Climbing Environment
  4. Destination and Diseases/Illnesses Common to the Region
  5. Medical History of Group Members
  6. Duration of Trip
  7. Distance from Definitive Medical Care and Availability of Rescue Assets
  8. Availability of Communications
  9. Space and Weight Considerations

The quantity of Essential items is dependent on all the above factors. Including the Recommended first aid items in your kit may depend on one or more of the considerations above.

Vertical Aid recommends using the PAWS acronym as a helpful guideline for organizing the creation of your first aid kit:

  • Prevention/Procedures
  • Analgesics/Antibiotics/Anaphylaxis
  • Wound Care
  • Survival

Pre-made vs. Custom-made

There are many very good pre-made kits on the market. I recommend looking at the Adventure Medical Kit (AMK) line. They have a wide range of kits for different group sizes, lengths of trips and activities.  For example, I carry the AMK Ultralight/Watertight .5 on local day hikes and a larger kit for multi-day backpacking trips.

AMK are a very good, inexpensive way to jump start your first aid kit. The AMK Ultralight/Watertight .9 is rated for 1-4 people, 1-4 days and contains many of the Essential items we will review in this article. When you try to build your own kit, you often have to buy large quantities of some items, enough to fill several kits.

Although the pre-made first aid kits are very good, you will still want to add (or remove) trip and group specific items.  The pre-made kit may contain items you will not need for your climate or time of year.  It will most certainly not contain all of the quantities of each items needed for a group.  For example, groups with kids will need more bandaids than groups with only adults. Conversely, the adults in the group may need more supplies of Ibuprofen and diarrhea medications.

My recommendation is start with an Adventure Medical Kit.  They are the best “bang for your buck”.  I suggest starting with the AMK Ultralight/Watertight .9 First Aid Kit or AMK Mountain Series Weekender First Aid Kit.  One of the added features of the Mountain Series over the Ultralight is the included Wilderness and Travel Medicine Guide Book.   It is good resource to have in the backcountry when you cannot Google treatments and symptoms. The trade off with the Mountain Series is that its case is not waterproof, like the Ultralight’s.

The NOLS Wilderness Medicine handbook says:

There is no such thing as the perfect first aid kit, so you should consider your needs and build a kit that meets them.

Below is an extensive list of first aid items for wilderness travel compiled from a number of different sources including NOLS, REI, NPS, Alpine Institute, ARC, and Vertical Aid. Many lists are just that lists. I wanted to create a comprehensive list AND give some explanation on the uses of each item.
