How to Choose the Right First Aid Kit for the Outdoors
When you’re heading into the outdoors, there’s a lot you can prepare for: the route, the weather, the gear. But it’s the things you can’t plan for that make a good first aid kit essential.
Whether you're hiking solo, taking on your Duke of Edinburgh (DofE) expedition, paddling downriver or tackling a multi-day trek, the right First Aid Kit can make all the difference when something doesn’t go to plan.
It’s a bit of kit that’s often overlooked, but arguably the most important one you pack. The piece of gear you hope you never have to use.
This guide will help you understand what to look for in an outdoor first aid kit, how to match it to your activity, and what sets a reliable kit apart from the rest.
Note: This guide is for individuals, families and outdoor groups. Lifesystems kits are designed for personal use, not for commercial or workplace first aid.
Lifesystems: Trusted by Adventurers Since 1989
For over 35 years, Lifesystems has been designing and building first aid kits trusted by DofE leaders, mountain instructors, expedition teams and everyday explorers. Every kit is developed in the UK, using quality-tested components chosen by medical professionals, from the British Special Forces to expedition doctor Hugh Montgomery.
Whether you’re walking a national trail or travelling overseas, our kits are built for real outdoor use. Lightweight, compact, and reliable when you need them most.
Why First Aid Kits Are So Important Outdoors
Outdoors, even small injuries can become big problems if you’re unprepared. A cut, blister, insect sting or sprain might be minor at home, but when you’re miles from help, quick access to treatment is vital.
A well-stocked first aid kit won’t just give you peace of mind. It can help prevent infection, ease discomfort, and allow you to continue your journey safely. For group leaders, it’s also a responsibility as being equipped to care for others is a core part of managing risk.
Key Factors to Consider When Choosing a Kit
1. Your Activity & Environment
Think about where you’re going and what you’re doing. Are you heading into the hills? Travelling abroad? Taking part in a race, cycling or watersport event?
Your kit should reflect the kind of risks you might encounter.
- For mountain walks or wild camping, cuts, blisters and strains are common.
- For overseas travel, sterility and medical standards matter.
- For wet or winter conditions, waterproofing is essential.
- For endurance events or long rides, weight and portability become the priority.
We’ll break this down further in the next section.
2. Group Size
The number of people you're responsible for will significantly affect which kit you need.
If you're heading out solo or as a couple, a compact kit like the Trek & Mountain or Light & Dry Nano may be ideal. These provide essentials without taking up much space.
However, if you're leading a group, whether it's a school expedition, a DofE trip, or an organised outdoor challenge, you’ll need a kit with greater capacity. The Mountain Leader and Mountain Leader Pro kits are designed to cater for groups of up to 14, with extra quantities of key items like bandages, dressings, gloves and antiseptic wipes.
Group kits are also structured for ease of delegation, enabling others to assist in treatment if needed, thanks to the clearly labelled QuickFind system.
3. Quality of Contents
This one’s non-negotiable. A first aid kit is only as good as what’s inside.
Lifesystems kits are made in the UK using quality-tested components selected by medical experts. Many items are the same as those used in professional settings. The kits are designed to withstand the demands of outdoor use, from trail injuries to more serious incidents in remote areas.
Every item is chosen with purpose. There’s no filler. Just gear that works when you need it.
4. Trauma Support
While most outdoor first aid kits are designed to deal with common issues like cuts, blisters, or minor sprains, there are situations where more serious injuries can occur. If you’re heading into remote areas, operating in high-risk environments, or travelling where help may take longer to arrive, you may want to consider adding a trauma kit to your setup.
Lifesystems has introduced a dedicated range of trauma kits (Trauma Pack & Trauma Pro Pack) designed to help manage injuries such as severe bleeding or broken bones. These kits contain essential tools to stabilise a situation and support someone until professional help is available.
Trauma kits are not a replacement for emergency services, but they offer additional reassurance and capability when minutes matter. If your trip involves technical terrain, off-grid travel or group responsibility, it’s worth factoring this level of cover into your decision.
5. Certifications & Safety Standards
While Lifesystems kits are not designed for commercial environments and don't fall under workplace standards like BS 8599, the components inside still meet stringent UK medical device regulations.
All sterile items, dressings, tapes and over-the-counter medications are registered with the MHRA (Medicines and Healthcare products Regulatory Agency) and carry the appropriate CE or UKCA certification. These align with ISO 13485 and ISO 14971 standards, ensuring high levels of safety, sterility and traceability.
So even though these kits are for personal outdoor use, the components inside are held to professional-grade medical standards.
When choosing a first aid kit, always check for these kinds of certifications to ensure the quality, safety and reliability of the contents.
6. Organisation & Ease of Access
When you need to act fast, you don’t want to be digging through a jumbled pouch of medical supplies.
Lifesystems kits are designed with a clear, structured internal layout. Our QuickFind System keeps items labelled, grouped and easy to locate, whether you’re dealing with a blister, burn or bleeding injury.
It’s a feature that makes all the difference in the moment so be sure that you can easily separate the items inside.
7. Durability & Weather Protection
Outdoor adventures rarely follow a neat script. Conditions can change quickly, and your gear needs to stand up to the challenge, particularly your first aid kit.
If you’re hiking through exposed terrain, caught in a downpour or paddling across open water, the last thing you want is a soaked kit or compromised contents. Wet dressings, soggy plasters and damp medications aren’t just frustrating; they can make treatment ineffective or even unsafe.
A waterproof or water-resistant kit adds an essential layer of protection. Lifesystems’ waterproof kits are designed with sealed zips and rugged outer cases to keep moisture out and ensure your contents stay dry and usable in all conditions. Whether you're stashing it in a drybag or clipping it to a kayak, it's gear you can rely on when things take a turn.
8. Room for Personal Medication
A good first aid kit should cover the essentials, but it also needs to work for you. Everyone’s health needs are different, and most people carry something specific: hayfever tablets, asthma inhalers, EpiPens, personal prescriptions or travel-related medication.
That’s why it’s important to choose a kit with a bit of flexibility. Lifesystems kits are designed with enough space to add your own items alongside the standard contents. Whether it’s a few extra plasters, a short course of antibiotics or a small supply of antihistamines, you should always tailor your kit to your needs and destination.
If you’re heading overseas, this becomes even more important. Think about country-specific health risks, such as stomach bugs, dehydration or insect bites, and make sure your kit is equipped to handle them. It’s much easier to bring what you need than to try finding it in an unfamiliar place.
9. Can You Refill It?
A first aid kit is only useful if it’s fully stocked. It’s easy to forget that you used a plaster, some antiseptic wipes or a bandage on your last trip. But over time, those small gaps can leave you unprepared when you need your kit the most.
When choosing a kit, it's worth checking whether it can be easily refilled. Some people continue buying entirely new kits once items run low, but this isn't always necessary. Lifesystems makes it simple to top up with a full range of refill packs available online. You can replace exactly what you need without paying for items you haven’t used.
Not only is this more convenient, it’s better for the planet too. Less waste, more value, and a kit that’s always ready when you need it.
Top tip: Before any trip, give your kit a quick check. Make sure nothing has gone missing, expired or been used up. Topping it up only takes a few minutes but could make all the difference when you’re out in the wild.
10. Don't Overpack - Choose a Kit That Matches Your Needs
It’s easy to think that more is better when it comes to first aid, but carrying a bulky, overstocked kit can be unnecessary and even counterproductive on certain adventures. If you’re heading out for a solo day hike or a quick overnight trip, you likely won’t need a kit designed for expedition groups.
Too much gear adds weight, takes up valuable pack space, and can slow you down. The goal is to carry what you’re likely to need – no more, no less.
That’s why Lifesystems offers a wide range of kit sizes to suit different types of users and activities. From our ultra-compact Mini Waterproof Kit to the Pocket or Solo Traveller Kit, you’ll find streamlined options that cover the essentials without weighing you down.
Think carefully about the length of your trip, the number of people you’re supporting, and the specific risks of your environment. A smaller, lighter kit that’s well-matched to your journey is more likely to stay with you – and be used when it’s needed.

Now You’ve Chosen Your Kit, What Next?
Choosing the right first aid kit is an important step, but it’s just the start. Here are three things to consider once your kit arrives to help you get the most from it when it really counts.
Get Familiar With Your Kit
A first aid kit is only effective if you know what’s in it and how to use it. Before setting off, take five minutes to open up your kit and familiarise yourself with the contents. Where are the gloves? What dressings do you have? Could you find the burn gel quickly if you needed to?
Every Lifesystems kit includes a Primary Care Leaflet, which outlines how to treat common outdoor injuries, what equipment to use, and what to do in an emergency. It’s a simple but vital guide that can help you stay calm and take the right action when it matters most.
The more confident you are with your kit, the more useful it becomes.
Consider First Aid Training
No matter how well-stocked your kit is, it’s your knowledge that makes the difference.
Investing in a first aid course is one of the best things you can do to stay safe outdoors. If you can, look for training that is specific to remote or wilderness settings. Outdoor environments bring unique challenges, from weather exposure to limited communication, and these courses are designed to help you adapt your response accordingly.
Training gives you the confidence to use your kit properly, treat injuries more effectively, and make better decisions in a high-pressure situation.
