What Should You Consider When Choosing a Backpack for Thruhiking?
When choosing a backpack for thruhiking, several factors are crucial to ensure comfort, durability, and functionality.
- Weight: A lighter backpack can significantly reduce fatigue over long distances, making it essential to find one that balances weight with durability. Aim for a pack that is lightweight yet sturdy enough to carry all your gear without compromising on support.
- Capacity: The size of the backpack should accommodate your gear while remaining manageable. Typically, a capacity between 50-70 liters is ideal for extended hikes, allowing enough space for essentials without being overly bulky.
- Fit and Comfort: A well-fitted backpack is crucial for preventing discomfort and injury on long hikes. Look for adjustable straps, a supportive hip belt, and a design that distributes weight evenly across your body.
- Durability: The materials used in the backpack should withstand the harsh conditions of the trail. High-denier nylon or polyester fabrics are often preferred for their resistance to tears and abrasions.
- Water Resistance: Since weather conditions can change rapidly while hiking, a water-resistant or waterproof backpack is beneficial for keeping your gear dry. Look for packs with water-resistant zippers or integrated rain covers to protect your belongings.
- Accessibility: Ease of access to your gear can enhance your hiking experience, so consider packs with multiple compartments and pockets. Features like side pockets for water bottles or front access can make it simpler to reach items without unpacking the entire bag.
- Ventilation: A backpack with good ventilation can help reduce sweat buildup on your back during long hikes. Mesh panels and a frame that allows airflow can enhance comfort and prevent overheating.
- Attachment Points: Additional gear often needs to be carried, so look for backpacks with external attachment points like daisy chains or bungee systems. These features allow you to securely fasten items such as trekking poles or sleeping pads.
- Weight Distribution: The design of the backpack should facilitate proper weight distribution to minimize strain. Packs with a load lifter system can help adjust the center of gravity, providing better stability while walking.
- Price: Budget is an important consideration, as a quality backpack can be a significant investment. Weigh the features against your budget to ensure you find a reliable pack that meets your needs without overspending.
What Size Backpack is Most Suitable for Thruhiking?
The most suitable backpack size for thruhiking typically depends on the duration of the hike and the gear needed, but generally falls between 50 to 70 liters.
- 50-60 Liters: This size is ideal for shorter thruhikes, usually lasting a week or less, where ultralight gear can be utilized.
- 60-70 Liters: A backpack in this range is better suited for longer hikes, providing extra space for additional gear and supplies, especially for those who prefer to carry a bit more comfort.
- Customizable Volume Backpacks: Some backpacks come with adjustable features allowing users to expand or compress the pack size depending on the load, making them versatile for varying trail conditions.
- Daypacks (20-30 Liters): While not suitable for long-term thruhiking, a daypack is beneficial for short day trips during a longer hike, allowing for easy access to essentials without carrying the full load.
Backpacks in the 50-60 liter range are perfect for hikers who prioritize weight savings and efficiency, as they can accommodate minimalist gear while still providing enough space for food and water for a week-long journey. These are commonly chosen by experienced hikers who have honed their packing skills and prefer to travel light.
On the other hand, 60-70 liter backpacks cater to those who might need additional comfort items or have bulkier gear, making them suitable for longer hikes where resupply points are limited. This size allows for a well-rounded packing strategy, accommodating sleeping bags, tents, and more food supplies.
Customizable volume backpacks are advantageous as they allow for flexibility in packing. These backpacks can be adjusted based on the hiker’s needs, making them ideal for varying trail conditions and for those who might find themselves needing to carry more gear at different times.
Daypacks serve a different purpose but are essential for the versatility they offer during a long thruhike. They allow hikers to break up their load and carry only necessary items for short excursions, ensuring that the full pack can remain at a base camp or during a longer rest period on the trail.
What Key Features Enhance Comfort in Thruhiking Backpacks?
Several key features enhance comfort in thruhiking backpacks:
- Adjustable Suspension System: An adjustable suspension system allows hikers to customize the fit of the backpack according to their torso length, which helps distribute weight evenly and reduces strain on the back and shoulders.
- Padded Shoulder Straps: Well-padded shoulder straps provide cushioning and support, preventing chafing and discomfort during long treks, while also helping to absorb some of the pack’s weight.
- Hip Belt with Load Lifters: A hip belt that features load lifters helps transfer the weight of the pack to the hips, enhancing stability and allowing for more efficient movement, especially on uneven terrain.
- Ventilated Back Panel: A ventilated back panel promotes airflow between the backpack and the hiker’s back, reducing sweat buildup and increasing overall comfort during hot weather or strenuous hikes.
- Multiple Adjustment Points: Having multiple adjustment points throughout the backpack enables hikers to fine-tune the fit and balance of the load, which is crucial for comfort over long distances.
- Compression Straps: Compression straps allow users to cinch down the load, which minimizes pack movement and enhances stability while hiking, leading to a more comfortable experience.
- Lightweight Materials: Utilizing lightweight yet durable materials in the construction of the backpack helps reduce overall weight, making it easier on the body during long hikes and allowing for greater energy conservation.
- Water-Resistant Fabrics: Water-resistant fabrics help keep gear dry in inclement weather, which can enhance comfort by preventing sogginess and maintaining warmth during hikes in rainy conditions.

- Ripstop Nylon: This material is lightweight yet incredibly strong, featuring a crosshatch pattern that prevents small tears from spreading. It’s often coated with silicone or polyurethane to enhance water resistance, making it a popular choice for backpack manufacturers.
- Cordura Fabric: Known for its toughness, Cordura is a high-performance nylon that resists abrasion, tears, and scuffs. It is commonly used in high-wear areas of backpacks and is available in various weights, which allows for both durability and weight optimization.
- Dyneema (Cuben Fiber): A premium material that is both ultralight and exceptionally strong, Dyneema is often used in high-end thruhiking backpacks. Its water-resistant properties and high tensile strength make it ideal for those seeking the lightest gear without compromising durability.
- Polyester:** This fabric is typically used in budget-friendly options, providing decent durability and water resistance. While not as strong as nylon or Cordura, modern polyester blends can still offer a good balance of weight and strength, suitable for casual thruhikers.
- Ballistic Nylon: Originally developed for military use, ballistic nylon is a thick, durable fabric known for its resistance to abrasions and punctures. While heavier than other materials, its robustness makes it ideal for rugged conditions and heavy loads.
How Do Various Backpack Capacities Affect Thruhiking Efficiency?
Various backpack capacities can significantly impact the efficiency and comfort of thruhiking.
- 30-50 liters: Ideal for short to moderate hikes where minimal gear is required, this capacity allows for easy maneuvering and lightweight packing. Hikers can efficiently carry essentials such as water, snacks, and a lightweight sleeping bag while ensuring they aren’t weighed down, which is crucial for maintaining energy over long distances.
- 50-70 liters: This range is suitable for longer hikes or those requiring extra gear, such as additional clothing or a more substantial cooking setup. The larger capacity facilitates better organization, enabling hikers to separate items into easily accessible compartments, which can save time and reduce fatigue during multi-day excursions.
- 70+ liters: Best for extended trips or when carrying heavier items like a tent and a comprehensive food supply, these backpacks can distribute weight across a larger frame. However, they can lead to overpacking, which may hinder mobility and increase overall fatigue, emphasizing the need for careful weight management to ensure efficiency.
- Adjustable capacities: Some backpacks come with adjustable features that allow for expansion or compression based on the hiker’s needs. This adaptability can enhance efficiency by providing flexibility for changing conditions, such as carrying more gear at the beginning of a trip and lightening the load as supplies diminish.
- Hydration pack capacity: Many thruhikers opt for a smaller, dedicated hydration pack alongside their main backpack, which can streamline access to water and snacks. This setup allows for quick hydration during breaks without the need to rummage through a larger pack, thus maintaining momentum on the trail.
