How to Choose the Right Backpack


– Measure your torso length to find the right size, and make sure to fit the backpack properly for maximum comfort and support.

Sizing your backpack

Choosing the right backpack size is key for comfort during your adventures. A well-sized pack helps you carry all your winter gear with ease.

  • Know that pack sizes are about how much they can hold, not how big they look.
  • Find out your torso length by measuring from the top of your shoulders to your iliac crest.
  • Pick a backpack that matches your torso length for the best fit.
  • Look at the size range given by manufacturers because each one can be different.
  • Try on different backpacks with some weight in them to see how they feel on your back.
  • Adjust the shoulder straps so they wrap around your shoulders without gaps.
  • Fasten and tighten the hipbelt over your iliac crest, not just where your pants sit.
  • Make sure the hipbelt doesn’t slide down when you walk around with the backpack on.
  • Check that you can easily reach and use all pockets and zippers while wearing it.

Fitting your backpack

Once you have the right backpack size, it’s time to make sure it fits well. Here is how to adjust your backpack for a snug and comfortable fit:

  • Measure your torso length and find a pack that matches. If your torso is longer or shorter than average, look for a pack with an adjustable harness.
  • Loosen all the straps before putting on your backpack. This makes it easier to adjust from scratch.
  • Put the backpack on and tighten the hip belt first. The belt should sit over your pelvic girdle and take most of the pack’s weight.
  • Adjust the shoulder straps so they wrap comfortably around your shoulders without any gaps.
  • Buckle the chest strap and slide it up or down to where it feels comfortable. It should not be too tight but firm enough to keep the shoulder straps in place.
  • Pull the load lifters near your collarbone until they are at about a 45-degree angle. These help balance and distribute the pack’s weight properly.
  • Check for any pressure points or loose areas after fully loading your backpack with gear. Make adjustments as needed.
  • Walk around with the loaded pack and ensure there’s no slipping or shifting. Your movements should feel natural, not hindered by the pack.

Customizing fit

To make your backpack fit just right, you can adjust parts like the waist belt and shoulder straps. Make sure these parts hug your body without squeezing too tight. A good fit means the backpack sits on your hips well and doesn’t move much when you walk.

For a perfect fit, change how tight or loose each part is until it feels best for you. You can do this before you go out with your pack or while on the trail to keep comfy all day long.

Now let’s talk about how small changes during a hike can help keep your load balanced and easy to carry.

Tweaking your pack on the trail

After customizing the fit of your backpack, it’s important to know how to make adjustments while on the trail. This will ensure that you maintain a comfortable and well-supported pack throughout your hike. Here are some essential tips for tweaking your pack on the trail:

  1. Check Your Straps: Periodically check and readjust your shoulder straps, hip belt, and load lifters as you hike to prevent any discomfort or strain.
  2. Weight Distribution: Be mindful of weight distribution within your pack, making small adjustments to keep heavy items centered and closer to your back.
  3. Balance Load: Regularly assess the balance of your pack by shifting items as needed to maintain stability and comfort while hiking.
  4. Ventilation: Adjust the back panel if your backpack offers ventilation features, ensuring proper airflow to minimize sweat and heat build-up.
  5. Accessory Attachment: Utilize external attachment points for quick access to gear or extra layers without having to open up the entire pack.
  6. Hydration Management: Keep an eye on hydration bladder tube placement and adjust its position for easy access while moving.
  7. Hip Belt Adjustment: Fine-tune the tightness of your hip belt based on changing terrain or fatigue levels, ensuring optimal weight transfer to reduce strain on shoulders and back.
  8. Quick Troubleshooting: Address any discomfort immediately by identifying pressure points or areas needing adjustment, like loose straps or uneven weight distribution.
  9. Pack Compression: Make use of compression straps to accommodate changes in gear volume throughout your hike, keeping the load stable and secure.
  10. Load Reassessment: Regularly reassess your gear needs based on weather conditions, time of day, fatigue levels, ensuring essential items remain easily accessible at all times.

Backpack Features to Consider

Consider the different features of a backpack, such as frame type, ventilation, and pack access. These factors can greatly impact your comfort and convenience while on the trail. Read on to learn more about choosing the right backpack for your winter gear.

Frame type

Internal frame packs are the top choice for most types of backpacking. They feature a built-in support structure, which provides stability and flexibility when navigating rugged terrain with winter gear.

External frame packs have a sturdy frame on the outside, offering specific functionalities and features suitable for rucksack sizing and winter gear. It’s crucial to consider the type of frame when selecting a backpack that will accommodate larger or bulkier items needed for cold weather adventures.

When choosing a backpack for winter excursions, understanding the distinctions between internal and external frames is essential. Internal frames offer versatility and stability, while external frames have distinct advantages such as better weight distribution.


When considering backpack features, ventilation is crucial for comfort during long hikes. Proper ventilation will prevent excess sweating and discomfort from heat buildup against your back.

Look for backpacks with mesh or trampoline-style backs to allow airflow between your back and the pack. This design helps to minimize moisture build-up, keeping you cooler and more comfortable during your outdoor adventures.

Ensure that the pack you choose has proper padding on the areas that come in contact with your body while allowing air circulation. Some packs also have channels or grooves to promote airflow, further enhancing ventilation.

Pack access

When you’re out on the trail, having easy access to your gear is crucial. Look for backpacks that offer multiple entry points, such as top-loading, front-panel access, or even side zippers.

These options make it easier to reach items packed deep in your bag without needing to unpack everything.

Pockets and compartments are also vital for organizing gear and keeping essentials within reach. Consider backpacks with hip belt pockets for snacks or small items you need frequently.


Shovel pockets, also called shove-it pockets, are open and handy. They’re sewn onto the back of a pack, great for stowing gear like snowshoes. Ski backpacks are specially designed with specific features that set them apart.

They have unique pocket design and structure to support skiing adventures.

In addition to these specialized pockets, there are various other types too- such as zippered hip belt pockets for small essentials or hydration reservoir sleeves inside the main compartment.

Understanding these different pocket options can help you choose a backpack that suits your winter adventure needs well.

Attachment points

When considering the features of a backpack, it’s important to pay attention to attachment points. These points on your pack are essential for securing and carrying various gear, especially during winter expeditions.

They allow you to tie down or hang items like trekking poles, ice axes, sleeping pads, sleeping bags, or even tent bodies. Some backpacks come with specific loops designed at the rear for securing sleeping pads, sleeping bags, or tent bodies while providing easy access.

Moreover, tool loops serve as a convenient feature that enables you to attach ice axes or trekking poles externally on the pack. This is particularly useful when navigating through wintry conditions and need quick access to these essential tools.


When you’re out on the trail and rain threatens to dampen your gear, a rain cover for your backpack becomes essential. The Osprey Ultralight rain cover offers a range of sizes to ensure the perfect fit for your backpack.

With its cinch attachment system, it securely stays in place, keeping your gear dry in light showers or heavy downpours.

Using a pack cover alone might not be enough to keep all water out during extended rains. Investing in a quality rain cover can give you peace of mind knowing that your essentials are protected from the elements, allowing you to stay focused on enjoying your outdoor adventures without worrying about wet gear.

Backpack Fit and Sizing Guide

To ensure proper fit, measure your torso length and waist size, and make additional adjustments as needed for a comfortable and secure fit during your winter adventures.

Torso length

Backpack size is determined by your torso length. It’s crucial to measure this before buying a backpack. Torso lengths can range from 14 to 19 inches, and each brand may have different sizing.

Some packs come in multiple sizes to cater to various torso lengths and genders, ensuring a better fit.

The height can give you an initial idea of which size might work for you, but measuring the torso and waist provides more accurate results. Backpacks are sized from extra small to large, accommodating various torso lengths for a comfortable fit during your winter adventures.

Waist size

To ensure a proper fit for your backpack, consider your waist size. The majority of the pack’s weight should be supported by the hips, so getting the right waist size is important.

Backpack hipbelts usually accommodate a wide range of hip sizes. It’s crucial to measure your waist circumference and reference the sizing chart provided by the manufacturer to find the appropriate size waist and yoke for a pack.

Sizing information for backpacks typically includes measurements for torso length, shoulder width, and most importantly, waist circumference. Each of these measurements plays an essential role in ensuring that you find a backpack that fits you comfortably and properly distributes the weight on your back and hips during your winter adventures.

Additional adjustments

When you have your pack on, make these additional adjustments for a perfect fit:

  1. Shoulder Straps: Adjust them so they snugly hug your shoulders, distributing weight evenly.
  2. Load Lifters: These straps connect the top of the shoulder straps to the pack, helping to pull the load closer to your body.
  3. Sternum Strap: This strap across your chest helps prevent shoulder straps from slipping.
  4. Hip Belt: Position it on top of your hip bones and tighten. It should transfer most of the pack’s weight to your hips.
  5. Compression Straps: Use them to keep items from shifting and stabilize your load.

Best Backpack Sizes for Winter Gear

Consider the length and type of your winter trip when choosing a backpack size. Larger trips may require a 50-70 liter pack, while smaller day hikes can make do with a 20-30 liter pack.

Measure your torso length and consider additional adjustments to find the perfect fit for carrying your winter gear.

What litre backpack do I need?

When choosing a backpack for winter gear, consider the trip length and gear weight. For 2-3 day trips, opt for a 50-65 liter backpack. However, some hikers may find a 45 liter pack suitable depending on their gear weight and preferences.

Winter camping or expeditions generally require over 75 liters to accommodate bulkier sleeping setups and mountaineering equipment.

It’s vital to choose the appropriate style of pack that matches your gear weight and preferred comfort level. Understanding backpack sizing is crucial in ensuring you have ample space without carrying unnecessary weight.

Recommended sizes for different trip lengths and types

Choosing the correct rucksack size for your winter adventure plays a crucial role in ensuring a comfortable and efficient journey. Here’s a guide to help you determine the best backpack size based on the length and type of your trip:

Trip Length Trip Type Recommended Size (Litres)
Day Trip Winter Hiking 20-30L
Overnight Winter Camping 30-50L
Weekend (2-3 days) Backcountry Skiing/Snowboarding 45-60L
Multi-day (3-5 days) Mountaineering 60-80L
Extended (5+ days) Expedition 80L+

Understanding backpack volume is essential in matching your gear with the task ahead. Keep in mind that winter equipment is typically bulkier and heavier. Adjust your size choice accordingly. Consider additional compartments and attachment points for winter-specific gear like ice axes and crampons. Next, let’s focus on how backpack volume is measured and the factors affecting your choice.

How backpack volume is measured

When choosing the right backpack size for winter gear, understanding how backpack volume is measured becomes essential. Backpack volume or capacity is typically measured in liters (L), with larger numbers indicating a bigger pack size.

The measurement reflects the total space inside the main compartment and additional pockets of the backpack. This volume determines how much gear and supplies a backpack can hold, making it crucial to consider when planning for winter trips where bulkier clothing and extra equipment are necessary.

To determine if a backpack can accommodate your winter gear, factor in not only your basic necessities but also any specialized items like snowshoes, ice axes, or avalanche safety tools.

Factors to consider when choosing a size

Backpack volume influences the size of the backpack, but it’s important to consider other aspects as well when choosing the right size for your winter gear. Here are several factors to consider:

  1. Trip Length: Longer trips require larger backpacks to accommodate extra gear and supplies, while shorter trips may necessitate a smaller pack.
  2. Gear Type: Bulky items such as sleeping bags, clothing layers, and additional cold-weather gear will require a larger backpack compared to compact or lightweight gear.
  3. Personal Comfort: The backpack should be large enough to carry all necessary gear comfortably without causing strain or discomfort during extended wear.
  4. Terrain and Conditions: Consider the type of terrain you’ll encounter and the weather conditions you expect; these affect what gear you need to carry, which in turn affects the size of the backpack required.
  5. Weight Distribution: A well-fitted backpack distributes weight evenly across your body, reducing strain on your back, hips, and shoulders. Ensuring proper fit is just as crucial as selecting an appropriate size.
  6. Storage Needs: If you plan on carrying extra equipment such as trekking poles, snowshoes, or ice axes for winter activities, ensure there are suitable attachment points and sufficient space for these items.
  7. Future Use: Consider potential future uses for the backpack when deciding on a size—purchasing a slightly larger pack might allow for versatility in different seasons or types of excursions.

Tips for finding the perfect fit

To find the perfect fit for your rucksack, follow these tips:

  1. Measure your torso length and hip size accurately to determine the right backpack size for you. This ensures a comfortable fit during long hikes or winter trips.
  2. Check if the backpack has adjustable features such as shoulder straps and hip belts to customize the fit according to your body shape and size.
  3. Experiment with different adjustments while wearing the fully loaded pack to ensure an even distribution of weight, reducing strain on your back and shoulders.
  4. Look for packs with load – lifter straps that help pull the weight closer to your body, improving balance and stability on challenging terrains.
  5. Consider trying on different packs with varying capacities before making a decision, ensuring the chosen one can accommodate all your winter gear without feeling too cramped or bulky.
  6. Pay attention to the padding on the shoulder straps, hip belt, and back panel to ensure adequate support and comfort while carrying heavier loads in colder conditions.
  7. Take into account any specific requirements or preferences you have, such as additional attachment points or pockets for organizing gear efficiently during winter adventures.


In conclusion, choosing the right rucksack size for winter gear is crucial. The tips provided here are practical and easy to implement. Have you considered measuring your torso length before selecting a backpack? By doing so, you ensure a perfect fit for your outdoor adventures.
