Video: How to Choose Backpacking Packs

Choosing the right backpack for your adventure can make a huge difference. It’s not just about how it looks; it’s about how well it fits, carries your gear, and stands up to the wild outdoors.

Videos are great tools to show you exactly what to look for. They often walk you through different pack sizes – whether you’re packing for an overnight trip or preparing for an extended hike.

Watch a video on choosing backpacking packs and you’ll learn loads of helpful tips. Look for one that goes over how to match a rucksack’s capacity with the length of your journey. The video should explain features like internal frames which give support, hydration reservoirs so you can drink water easily while walking, and rain covers to keep everything dry.

Good videos also cover why things like hip belt fit and shoulder strap adjustment matter.

These kinds of videos demonstrate putting on different types of packs too. See someone adjust all those straps until they get a perfect fit around their torso and waist—just like you would need to do yourself! This isn’t just useful; it’s practical advice that’ll help ensure your load is balanced right so that every step on the trail is as comfortable as possible.

Types of Backpacks (Weekend, Multiday, Extended-trip)

  • Weekend Backpacks (30-40 liters):
  • Perfect for one or two nights out.
  • Just the right size for your main items like a sleeping bag, food, and clothes.
  • Many have special pockets for quick access to snacks or a map.
  • Ventura 40L is a popular choice with enough space for weekend warriors.
  • Multiday Backpacks (45-70 liters):
  • Designed for trips that last three to five days.
  • They have more room for extra food and layers of clothing.
  • You’ll find features like hydration reservoirs to keep water handy.
  • These packs often include straps on the outside to attach things like a sleeping mat.
  • Extended-trip Backpacks (60+ liters):
  • Made for adventures longer than five days.
  • They can hold camping gear and lots of food.
  • Bigger backpacks usually come with more support to handle heavier loads.

Important Features to Consider

A backpack surrounded by lush greenery and people in various styles.

Consider the frame type, ventilation, pack access, pockets, removable daypack, sleeping bag compartment, additional attachment points, raincover, and hydration reservoir when choosing a rucksack.

Frame Type

Rucksacks come with different types of frames: internal frame, external frame, and frameless. Internal frame backpacks are popular because they’re light and fit close to your body.

This makes them good for hiking and trekking as they won’t throw you off balance on tricky trails. They can hold a lot without needing metal stays unless you pack over 30 pounds.

External frame packs are great when you need to carry heavy loads. They have a sturdy structure that lets you strap on things like sleeping bags or tents with ease. Frameless rucksacks are the simplest type and work well for light trips or fastpacking where every ounce counts.

Each style has its own perks so think about what’s most important for your adventure before picking one out.


When it comes to selecting a rucksack, ventilation is crucial. Proper ventilation in a backpack helps prevent moisture buildup and sweat, ensuring the user stays dry and comfortable during outdoor activities.

This is especially important for preventing odor and bacteria accumulation, maintaining hygiene and cleanliness in the rucksack. Moreover, good ventilation also regulates temperature and prevents overheating during strenuous outdoor activities.

Additionally, proper ventilation plays an essential role in preventing bacterial growth inside the rucksack which can lead to odors and unhygienic conditions while on extended trips or camping expeditions.

Pack Access

When selecting a backpack, considering pack access is crucial. Look for features that allow easy access to your gear, like front-loading zippers or panel access. This makes it simple to reach items at the bottom of your pack without unpacking everything.

Another essential feature for pack access is multiple entry points. Top-loading backpacks are common but having side or bottom entry can make it easier to find what you need quickly.

Additionally, specialized compartments and pockets contribute to better organization and accessibility within the pack.

As you look into rucksacks, consider how easily you can get inside them both during travel and on the trail. Ensuring efficient pack access will improve your overall experience with the backpack.


Backpack pockets are essential for keeping your gear organized and accessible. Look for a backpack with multiple pockets to keep small items handy without having to take off the pack.

Top pockets offer better organization and easy access, while side mesh pockets are useful for storing water bottles or snacks on the trail. Whether it’s a credit card, first aid kit, or a bivvy bag, the number and placement of pockets matter for efficient organization and accessibility during your outdoor adventures.

Now that we’ve covered how important backpack pockets are for staying organized on the trail, let’s move on to understanding another crucial feature – removable daypacks.

Removable Daypack

A detachable daypack is a useful feature found in some backpacks, offering versatility for different activities. These daypacks have similar features to regular backpacks and can be handy for day trips or short excursions.

Nearly half of travel backpacks come with removable daypacks, providing added convenience for travelers who may need a smaller pack for shorter outings.

To choose the right backpack with a removable daypack, consider your specific needs and the type of activities you’ll be doing. Taking into account the features mentioned earlier will help ensure that the detachable daypack meets your requirements.

Opting for a travel backpack with this feature can offer flexibility and practicality during your adventures, making it easier to adapt to varying situations while on the go.

Sleeping Bag Compartment

When it comes to organizing your backpack for a hiking or camping trip, the sleeping bag compartment plays a crucial role. This dedicated space allows you to properly store and access your sleeping bag without having it take up room in the main compartment of your pack.

Many backpacks feature a zippered sleeping bag compartment, which not only provides easy access but also helps with internal compression and organization. When choosing a hiking backpack, consider the size and accessibility of the sleeping bag compartment along with other essential pockets such as hipbelt pockets and top lid pocket.

The separate storage area for a sleeping bag is designed to enhance convenience during trips, ensuring that this bulky item does not interfere with accessing other gear or supplies in the main part of the pack.

Additional Attachment Points

When considering a camping backpack, it’s crucial to pay attention to the additional attachment points. These points allow you to fasten extra gear and accessories onto your pack. They include loops, daisy chains, and webbing designed for attaching items externally.

These attachment points can be very helpful as they offer versatility and customization options in carrying extra gear like trekking poles or a sleeping bag while on the trail.

It is important to note that some backpacks have specific attachment points for ice axes, crampons, or other specialized outdoor equipment. The type and placement of these attachment points affect how you organize and carry your gear.


When it comes to keeping your belongings dry during outdoor adventures, a rain cover is an essential accessory for your backpack. It helps protect your gear from getting wet in rainy conditions, ensuring that your items stay safe and dry.

The best rain covers are designed to be easy to use and transport, making them convenient for hikers, campers, and mountaineers. Look for a rain cover with a small pack size for easy storage and portability while providing reliable protection against the elements.

Ensuring all items remain dry is crucial during any outdoor activity; thus investing in the best backpack rain covers for 2023 will provide peace of mind as you embark on your hiking or camping trips.

Hydration Reservoir

When it comes to choosing a backpack, the consideration of a hydration reservoir is crucial for staying hydrated during various activities such as hiking, running, or cycling. Hydration reservoirs typically come in capacities ranging from 1.5 liters to 3 liters, providing a convenient way to carry water.

It’s important to note that these reservoirs add extra weight even before being filled with water; so consider your overall pack weight when selecting one. Additionally, proper maintenance and cleaning are essential for keeping the hydration reservoir in good condition.

Remember that hydration packs for day hikers are designed specifically to provide easy access to water during half- or full-day hikes. Consider the capacity of the reservoir along with other features such as additional attachment points and ventilation when making your selection.

Choosing the Right Fit

Consider your torso length and waist size when choosing a backpack. Look for adjustable back straps, women-specific fits, and additional adjustments for a better fit.

Torso Length

Backpack sizes correspond to different torso lengths, usually ranging from 15-20 inches, with specific sizes for each length. To measure your torso length accurately, start at the base of your neck and measure down to the top of your hips.

This measurement is crucial for finding a backpack that fits comfortably while you’re out backpacking. If you find that tightening the sternum strap doesn’t keep the shoulder pads on your shoulders, it might indicate that you need a larger pack size based on your torso length.

Understanding how to measure your torso length ensures you find a backpack that provides a comfortable fit during your outdoor adventures. As every individual’s body is unique, knowing this measurement will help in choosing the right-sized pack for an enjoyable backpacking experience.

Waist Size

When choosing a backpack, your waist size is crucial for finding the right fit. The hipbelt should snugly wrap around your hips at the iliac crest to provide proper support. This measurement is essential, as the hipbelt supports most of the backpack’s weight.

It’s not about your actual waist size but rather how it fits around your hips.

Next, let’s talk about ‘Women-Specific and Youth-Specific Backpacks’.

Women-Specific and Youth-Specific Backpacks

When considering backpacks, it’s crucial to account for the specific needs of women and youth. This ensures a comfortable and secure fit for smaller frames. Here are important considerations when selecting women-specific and youth-specific backpacks:

  1. Tailored Fit: These backpacks are designed to accommodate the smaller, curvier body shapes of women and youth, ensuring a more comfortable and ergonomic fit.
  2. Proper Support: Women-specific packs provide adjustments in the hip belt, harness, and torso length to cater to the anatomical differences in female bodies while youth-specific packs are scaled down in size.
  3. Weight Distribution: Both types of backpacks are engineered to distribute weight effectively on smaller frames, preventing strain and discomfort during extended use.
  4. Durability and Safety: These packs often incorporate durable materials suitable for outdoor activities while offering safety features relevant to the age group using them.
  5. Stylish Design: Many women-specific packs come in designs that reflect women’s preferences in color schemes and styles.

Additional Adjustments for a Better Fit

To ensure the best fit for your backpack, consider these additional adjustments:

  1. Adjust the load lifters to form a 45-degree angle between the shoulder straps and the pack. This helps in achieving a comfortable fit by distributing weight effectively.
  2. Secure the sternum strap at an appropriate height to stabilize the backpack and distribute weight evenly.
  3. Tighten the hip belt to provide crucial support and stability while carrying the backpack.
  4. Ensure proper adjustment of waistbelts, whether they are fixed or adjustable, to achieve a secure and personalized fit.
  5. Utilize the available yoke and waist belt adjustments beyond the listed size range for optimal comfort and support.

Tips for Packing a Camping Backpack

When packing a camping backpack, follow these tips for optimal comfort and organization:

  1. Use stuff sacks to compartmentalize your belongings and maximize space inside the pack. This will help keep items organized and easy to access.
  2. Place heavier items, such as camp stoves or food, closer to your body for a more comfortable carry. This also helps maintain balance and stability while hiking.
  3. Pack the heaviest items towards the bottom of the backpack and lighter objects towards the top when fitting in a tent. This arrangement ensures better weight distribution and easier handling.
  4. Consider the weight, balance, and organization of your gear when loading the backpack to optimize comfort during your camping trip.
