Choosing the Right Size for Your Survival Backpack

Welcome fellow adventurers and survivalists! When it comes to preparing for the unexpected, having the right gear can make all the difference. One of the key elements of your survival arsenal is your backpack. In this blog post, we will delve into the crucial decision of choosing the right size for your survival backpack. Whether you are planning a wilderness expedition, are a seasoned hiker, or simply want to be prepared for emergencies, selecting the appropriate size pack can ensure you have everything you need when it truly counts. Let’s explore together how to find the perfect fit for your unique needs and adventures.

Factors to Consider

When preparing for a survival situation, one of the most critical decisions you’ll make is selecting the appropriate size for your survival backpack. The size of your backpack will directly impact your comfort, mobility, and ability to carry essential items for your trip. To help you determine the right size for your needs, consider the following factors:

Duration of Trip

The length of your trip plays a significant role in determining the size of your survival backpack. Shorter trips require less gear and supplies, while longer trips necessitate more storage space. Consider the following guidelines when choosing the size based on trip duration:

  • Day Trips: For day trips or short outings, a compact backpack with a capacity of around 20-30 liters should provide ample space for essentials such as water, snacks, a first aid kit, and emergency supplies.
  • Weekend Getaways: Weekend trips typically call for a backpack with a capacity of 30-50 liters to accommodate additional clothing, food, shelter, and other essentials for a couple of days in the wild.
  • Extended Expeditions: For longer excursions lasting multiple days or weeks, opt for a larger backpack with a capacity of 50 liters or more to carry extra clothing, cooking gear, shelter, and survival tools.

Number of People

Consider how many people will rely on the contents of the survival backpack. If you are responsible for supplies for a group, you may need a larger backpack to accommodate the shared gear. Keep in mind the following considerations:

  • Solo Traveler: If you are traveling alone, a smaller backpack may suffice, but ensure it has adequate space for all necessary items.
  • Group Trips: When venturing with a group, consider a larger backpack with a capacity of 60-70 liters or more to accommodate shared supplies and distribute the weight among the members.

Type of Environment

The environment in which you plan to use your survival backpack will impact the size and features you need. Different environments require specialized gear and equipment, influencing the size of the backpack. Consider the following scenarios:

  • Warm Climate: In warm climates, you may need less insulation and bulkier clothing, allowing for a smaller backpack with a capacity of 40-50 liters to carry essential gear and water.
  • Cold Climate: Cold climates require additional clothing layers, insulation, and larger gear, necessitating a backpack with a capacity of 50-70 liters to accommodate bulkier items and winter-specific gear.
  • Harsh Terrain: If your trip involves challenging terrain or remote locations, opt for a rugged backpack with durable materials and a capacity of 60 liters or more to withstand rough conditions and carry emergency supplies.

By carefully considering the duration of your trip, the number of people relying on the backpack, and the type of environment you will encounter, you can select the right size backpack that meets your specific needs. Remember to test the pack’s fit and comfort before embarking on your adventure to ensure a successful and enjoyable journey.

Capacity Options

When it comes to choosing a survival backpack, one of the key considerations is its capacity. The capacity of a backpack refers to the volume of space it offers for storing essentials such as food, water, clothing, shelter, and other survival gear. Different capacity options cater to varying needs and durations of use, from day trips to extended expeditions. In this article, we will delve into the various capacity options available for survival backpacks, including daypacks, 3-day packs, and larger expedition packs, highlighting the pros and cons of each.


Capacity: Daypacks typically range from 10 to 30 liters.


  • Lightweight and compact
  • Ideal for short hikes and day trips
  • Just enough space for essentials like water, snacks, a first aid kit, and a light jacket
  • Easy to carry and maneuver


  • Limited space for bulky items or extended supplies
  • Not suitable for overnight stays or longer excursions

Examples: The Osprey Daylite Daypack or the North Face Recon Pack.

3-Day Packs

Capacity: 3-day packs usually offer 30 to 50 liters of storage space.


  • Perfect for weekend trips or short-term emergencies
  • Sufficient room for food, water, clothing, shelter, and essential gear
  • Balance between capacity and portability


  • May become heavy when fully packed
  • Not ideal for extended survival situations exceeding three days

Examples: Consider the Teton Sports Scout 3400 Internal Frame Backpack or the Kelty Redwing 44 Backpack.

Larger Expedition Packs

Capacity: Expedition packs typically range from 50 liters and above.


  • Ample space for extended survival scenarios or multi-day expeditions
  • Ability to carry more supplies and gear for comfort and safety
  • Designed with durability and load-bearing capacity in mind


  • Heavier and bulkier than smaller packs
  • Overkill for short trips or day hikes

Examples: Look into the Gregory Baltoro 65 Pack for a high-capacity option or the Arc’teryx Bora AR 63 Backpack.

In conclusion, selecting the right capacity for your survival backpack is crucial for ensuring you have the necessary supplies for your outdoor adventures or emergency preparedness. Consider the duration of your trip, the amount of gear you need to carry, and your comfort level when deciding on the most suitable capacity option. By choosing the right backpack size, you can enhance your overall experience and readiness for any situation.

This breakdown of capacity options for survival backpacks aims to guide you in making an informed decision based on your specific needs and preferences. Remember, having the right backpack can make all the difference in your outdoor experiences and emergency readiness. Choose wisely and stay prepared for any adventure that comes your way.

Fit and Comfort

When it comes to selecting a survival backpack, fit and comfort should be at the top of your priority list. A well-fitted backpack not only ensures your comfort during long treks but also plays a crucial role in your overall survival preparedness. Let’s delve into why getting the right size and ensuring proper weight distribution are essential aspects to consider.

Importance of Proper Fit

Avoiding Discomfort and Injury

Carrying a backpack that doesn’t fit properly can lead to discomfort and even injury. A backpack that is too large or too small for your body frame can cause strain on your shoulders, back, and hips. This can significantly impact your ability to travel long distances efficiently during survival situations.

Improved Mobility and Balance

A properly fitting backpack allows for better mobility and balance, enabling you to navigate through various terrains with ease. Whether you need to scramble over rocks or maneuver through dense vegetation, a well-fitted backpack will enhance your agility and overall performance.

Ensuring Even Weight Distribution

Preventing Strain and Fatigue

Proper weight distribution is key to preventing strain and fatigue over extended periods of wear. Unevenly distributed weight can lead to muscle fatigue, making it challenging to sustain physical exertion when every ounce counts in a survival scenario.

Tips for Ensuring Even Weight Distribution

  • Adjustable Straps: Look for backpacks with adjustable shoulder, chest, and hip straps to customize the fit according to your body shape.
  • Load Lifters: Utilize load lifters to pull the weight closer to your body, reducing strain on your shoulders and back.
  • Hip Belt: Ensure the hip belt sits snugly around your hips, transferring the majority of the weight to your lower body for better balance and comfort.

Additional Features to Consider in a Survival Backpack

When choosing a survival backpack, there are several additional features you should look for to ensure it meets your needs in various situations. These features can greatly enhance the functionality and utility of your backpack, making it an essential tool for any outdoor adventure or emergency situation.

Compartments and Organization

One crucial feature to consider is the number and layout of compartments in the backpack. Having multiple compartments allows for better organization of your gear, making it easier to access items quickly when needed. Look for backpacks with a combination of large main compartments, smaller pockets, and even specialized compartments for specific items such as a hydration bladder, electronics, or first aid kit.

Example: The Teton Sports Scout 3400 backpack features multiple compartments, including a sleeping bag compartment, side pockets, and a front pocket for easy access to essentials.

Water Resistance

A water-resistant backpack is essential for protecting your gear from the elements, especially in unpredictable weather conditions. Look for backpacks made from waterproof materials or equipped with a rain cover to ensure your belongings stay dry and secure. Water-resistant zippers and sealed seams are also important features to prevent water from seeping into the compartments.

Example: The Mardingtop 65+10L Tactical Backpack is made from water-resistant fabric and comes with a rain cover to provide added protection during rainy conditions.

Durability and Material

Durability is a crucial factor when selecting a survival backpack, as it needs to withstand rough handling, abrasion, and harsh environments. Look for backpacks made from high-quality, tear-resistant materials such as nylon or Cordura, which offer excellent durability without adding unnecessary weight. Reinforced stitching, robust buckles, and heavy-duty zippers are also important features to ensure the backpack can withstand heavy loads and frequent use.

Example: The Osprey Atmos AG 65 backpack is constructed from durable nylon fabric with reinforced stitching and YKK zippers, making it a reliable choice for long-term use in rugged conditions.

Size Selection Considerations

The additional features of compartments, water resistance, and durability can influence the size selection of your survival backpack. Here’s how these factors play a role in determining the ideal size for your needs:

  • Compartments: If you carry a lot of gear or need to organize various items, opt for a larger backpack with multiple compartments to accommodate your belongings efficiently.
  • Water Resistance: For outdoor activities in wet environments or regions with unpredictable weather, choose a larger backpack with water-resistant features to protect your gear effectively.
  • Durability: If you plan to use the backpack for extended trips or in rugged terrain, opt for a larger size that can accommodate heavier loads without compromising durability.

By considering these additional features and how they impact your size selection, you can choose a survival backpack that meets your specific needs and provides reliable performance in any situation.

Selecting the Perfect Fit

In conclusion, selecting the appropriate size for your survival backpack is crucial for meeting your individual needs. It is essential to consider factors such as capacity, weight distribution, and comfort when deciding on the right size. We recommend trying out various sizes before making a purchase to ensure that your survival backpack fits perfectly and supports you effectively during any emergency situation.
