The 18-liter volume comfortably fits shoes, a jacket, water, and snacks, while the low-profile fit keeps it close to your back, even in tight chimneys.

Compared to the Osprey Mutant 38L, which is more specialized for alpine adventures, or the PETZL BUG for Multi-Pitch Climbing in red, the gray version offers a perfect balance of lightness, storage, and versatility—making it the best choice for most climbers I’ve tested.

What Are the Key Features of the Best Backpack for Climbing?

The best backpack for climbing should encompass several key features to enhance functionality and comfort during outdoor adventures.

• Durability: A climbing backpack must be made from robust materials that can withstand rough terrain and harsh weather conditions. High-denier nylon or polyester fabrics are typically used, providing resistance to abrasions and tears while maintaining a lightweight profile.
• Comfort and Adjustability: A well-designed climbing backpack should have adjustable straps and a padded harness to ensure a snug fit. This feature is crucial for distributing weight evenly, reducing strain on the back and shoulders during long climbs.
• Capacity and Organization: The ideal backpack should have ample storage space, typically ranging from 30 to 70 liters, depending on the length of the climbing trip. Multiple compartments, pockets, and gear loops help in organizing climbing equipment, making it easy to access essential items quickly.
• Hydration System Compatibility: Staying hydrated is vital while climbing; therefore, a backpack with a hydration reservoir pocket or compatible water bottle sleeves is advantageous. This feature allows climbers to carry water easily and access it without having to stop and unpack their gear.
• Lightweight Design: A lightweight backpack is essential for climbing to minimize fatigue. Manufacturers often utilize lightweight materials and streamlined designs to ensure that the pack does not add unnecessary weight while still providing durability and functionality.
• Weather Resistance: A climbing backpack should offer some level of weather resistance, such as a water-repellent finish or a rain cover, to protect gear from rain and snow. This feature is crucial for maintaining the integrity of climbing equipment and personal belongings during unexpected weather changes.
• Gear Attachment Options: The best climbing backpacks come with various attachment points for gear such as rope, carabiners, and ice axes. These external attachment options allow climbers to carry essential tools securely while keeping internal compartments free for other items.

How Do You Choose the Right Size for a Climbing Backpack?

Choosing the right size for a climbing backpack is crucial for comfort, efficiency, and safety during your climbing adventures.

• Day Packs (15-30 liters): Ideal for short climbs or day trips, these backpacks are lightweight and compact. They typically have enough space for essentials like water, snacks, a first-aid kit, and climbing gear without being cumbersome.
• Weekend Packs (30-50 liters): These are suitable for multi-day climbing trips where you need to carry additional gear like sleeping bags and cooking equipment. They offer a balance between capacity and weight, allowing you to pack efficiently while maintaining mobility.
• Expedition Packs (50+ liters): Designed for long trips or technical climbs, these larger backpacks provide ample space for all necessary gear, including specialized equipment. They often feature multiple compartments for organization and are built to support heavier loads comfortably.
• Fit and Comfort: The fit of a climbing backpack is as important as its size. Look for adjustable straps, padded hip belts, and back panels that provide support and distribute weight evenly, which is essential during long climbs.
• Climbing Gear Compatibility: Ensure that the backpack is compatible with your climbing gear, including features like gear loops, hydration reservoirs, and external attachment points for ropes or helmets. This will enhance your convenience and accessibility while climbing.
• Materials and Durability: Consider the materials used in the backpack’s construction, as durability is critical for climbing environments. Look for water-resistant or waterproof fabrics that can withstand rough conditions and wear and tear.

What Materials Should You Look for in a Climbing Backpack?

When selecting the best backpack for climbing, it’s essential to consider materials that enhance durability, weather resistance, and comfort.

• Nylon: Nylon is a widely used material for climbing backpacks due to its high strength-to-weight ratio and resistance to abrasions. It is lightweight yet durable, making it ideal for carrying gear without adding excessive weight. Additionally, nylon can often be treated with water-resistant coatings to protect against moisture.
• Polyester: Polyester is another popular fabric for climbing backpacks, known for its durability and UV resistance. It maintains its color and strength even after prolonged exposure to sunlight, making it a good choice for outdoor activities. While it may not be as strong as nylon, it is often more affordable and still provides decent weather protection.
• Ripstop Fabric: Ripstop fabric is characterized by its grid pattern, which helps prevent tears from spreading. This makes it an excellent choice for climbing backpacks that may experience rough handling or contact with sharp rocks. The lightweight nature of ripstop fabric allows for easy carrying without compromising on strength.
• Waterproof Coatings: Many climbing backpacks come with waterproof coatings or are made from waterproof materials to keep your gear dry in wet conditions. These coatings, such as polyurethane (PU) or silicone, provide an extra layer of protection against rain and snow, essential for unpredictable weather during climbs.
• Breathable Mesh: Breathable mesh is often used in the back panel and shoulder straps of climbing backpacks to enhance comfort during long hikes. This material allows for airflow, reducing sweat buildup and keeping you cooler. It also adds some cushioning without adding significant weight.
• Reinforced Seams: Reinforced seams are crucial for ensuring the longevity of climbing backpacks, as they provide extra strength at stress points. These seams are typically double-stitched or use bar-tack stitching, which prevents ripping and enhances the overall durability of the backpack. Strong seams are vital for carrying heavy gear safely and securely.
• Durable Hardware: The buckles, zippers, and other hardware on a climbing backpack should be made from high-quality materials such as aluminum or tough plastic. Durable hardware ensures that the backpack can withstand the rigors of climbing, including frequent openings and closures, without breaking or failing. Look for weather-resistant zippers to further protect your gear.

What Are Common Mistakes to Avoid When Selecting a Climbing Backpack?

• Ignoring Weight Distribution: Many climbers overlook how the weight is distributed within the pack. Proper weight distribution is crucial for balance and comfort during climbs; items should be packed in a way that heavier items are closer to your back and lighter items are further away.
• Neglecting Material Quality: Opting for a cheaper backpack made from inferior materials can lead to durability issues. High-quality materials are essential for withstanding harsh weather and rough conditions, which are common in climbing scenarios.
• Forgetting About Hydration Options: It’s easy to overlook hydration when selecting a climbing backpack. A good climbing pack should have the option for a hydration reservoir or external pockets for water bottles to ensure you stay hydrated during long climbs.
• Overlooking Comfort Features: Some climbers may focus solely on capacity and neglect comfort features such as padded straps, a hip belt, and back ventilation. These features are important to reduce fatigue and improve airflow, making your climb more enjoyable.
• Not Considering Accessibility: Accessibility to gear while climbing is often underestimated. Look for backpacks that offer side access or top-loading options, which can help you retrieve essential items without having to unpack the entire bag.
• Ignoring Compatibility with Climbing Gear: It’s vital to ensure the backpack is compatible with your climbing gear, such as rope, harness, and carabiners. A well-designed climbing backpack will have gear loops, attachment points, and internal organization to keep your climbing essentials handy.
