How We Tested: Evaluating External Frame Backpacks
Our recommendations for the best external frame backpacks aren’t based on casual impressions. We prioritize a data-driven approach, analyzing specifications, user reviews, and comparative data from leading retailers and outdoor gear review sites like OutdoorGearLab and Switchback Travel. We focused on key performance indicators (KPIs) including load capacity, frame material (primarily aluminum frame durability), suspension system adjustability (torso length, shoulder strap configuration), and user-reported comfort levels for extended hikes with heavy loads.
While comprehensive physical testing of every pack isn’t always feasible, we relied heavily on analyzing real-world feedback regarding weight distribution, stability on varied terrain, and long-term durability. We cross-referenced features like attachment points and organizational pockets against the needs outlined in our buying guide, evaluating how effectively each external frame backpack addresses common use cases – from multi-day backpacking to hunting expeditions. Capacity (measured in liters) was benchmarked against typical gear lists for different trip durations. We also considered materials’ denier (e.g., 600D fabric) as an indicator of abrasion resistance and overall pack longevity.
Choosing the Right External Frame Backpack
External frame backpacks are ideal for carrying heavy, bulky loads, making them popular for hunting, backpacking, and extended outdoor trips. However, selecting the right one requires careful consideration. Here’s a guide to help you navigate your options.
Capacity & Intended Use
The first step is determining the appropriate capacity (measured in cubic inches or liters) based on your typical trip length and gear needs. Shorter, overnight trips might only require 50-70 liters (around 3000-4300 cubic inches), while multi-day hunts or backpacking adventures could demand 70-90+ liters (4300-5500+ cubic inches). Consider what you’ll be carrying – are you hauling game meat, bulky camping equipment, or a combination? Larger capacity packs are heavier even when empty, so don’t overestimate your needs.
Frame & Load Capacity
The frame is the backbone of these packs, and material matters. Aluminum frames (found in models like the TR Aluminum and ZRSCHYG Aluminum options) offer a good balance of weight and durability. A robust aluminum frame is crucial if you plan on consistently carrying heavy loads. The load capacity, typically measured in pounds or kilograms, is a vital specification. Look for a pack that can comfortably handle your expected load with some margin. A higher load capacity generally means a sturdier frame, but also potentially more weight. Some packs, like the External Frame Backpack Load 132.3lb, specifically highlight their high weight capacity for serious hauling.
Comfort & Adjustability
Carrying a heavy load comfortably is paramount. Pay attention to these features:
- Suspension System: Look for adjustable shoulder straps with dense foam padding. A wrap-around waist belt is essential for transferring weight to your hips, reducing strain on your back. Breathable mesh back panels (present in many models) help improve ventilation and minimize sweating.
- Torso Length Adjustment: External frame packs need to be properly fitted to your torso length for optimal weight distribution. Many models, such as the TR Aluminum External Frame Backpack, offer adjustable frame heights to accommodate different body types.
- Ergonomic Design: A frame that conforms to the natural curvature of your spine will significantly improve comfort, especially during long hikes.
Additional Features
Beyond the core features, consider these:
- Attachment Points: External frame packs excel at carrying items outside the main compartment. Look for multiple straps and attachment points for securing sleeping bags, tents, or game.
- Organization: Pockets and compartments help keep your gear organized and accessible.
- Durability: Fabric quality (like the 600D fabric found in several models) and buckle strength contribute to the pack’s longevity.
- Weather Protection: Some packs, like the ZRSCHYG Hunting Pack Frame Rain Cover, include a rain cover for protecting your gear in wet conditions. Noise-reducing fabric (like the “noise free next camo g2” in the TIDEWE Hunting Backpack) is a bonus for hunters.
- Specialized Features: Hunting-specific packs often include features like bow or rifle carriers (TIDEWE) and camouflage patterns (TR Aluminum).
The Bottom Line
Choosing the best external frame backpack depends heavily on your specific needs and anticipated load weight. By carefully considering capacity, frame material, adjustability, and additional features, you can find a pack that provides the comfort and durability required for your adventures.
Ultimately, a well-fitted external frame backpack is a valuable investment for anyone regularly carrying heavy gear over long distances. Prioritize a robust aluminum frame and a comfortable suspension system to ensure a stable and enjoyable experience on the trail or in the field.
