The Osprey Atmos AG 65 is renowned for its revolutionary Anti-Gravity suspension system. This design uses a flexible, trampoline-like mesh backpanel that creates a space between the pack and your body, significantly improving airflow and comfort. The result is a carrying experience that genuinely feels lighter, as the weight is expertly distributed and the suspension minimizes pressure points.
Customization is key for long-distance comfort, and this pack delivers with its adjustable harness and Fit-on-the-Fly hipbelt. This allows you to fine-tune the fit while you’re on the move, adapting to your body and the terrain. Practical features like the front stretch mesh pocket offer quick and easy storage for rain gear or an extra layer, keeping essentials within reach without having to open the main compartment.

Buying Guide: How to Choose a Multi-Day Hiking Backpack
Choosing the right pack for a multi-day trip is one of the most important gear decisions you’ll make. Get it wrong, and you’re in for a world of discomfort; get it right, and you’ll barely notice it’s there. I always start by thinking about capacity. For trips lasting three to five days, a pack between 50 and 70 liters is my sweet spot. This gives me enough room for my shelter, sleep system, food, and clothing without being so large that I’m tempted to overpack. If I’m heading out for a week or need to carry bulky winter gear or specialized equipment, I might look at models pushing 80 liters.
The next thing I obsess over is the fit. A backpack is not a one-size-fits-all item. Torso length is the most critical measurement, not your height. Most good packs come in multiple torso sizes (like Small, Medium, Large) and have adjustable harness systems. I make sure to try it on with weight in it, either at a store or by ordering from a retailer with a good return policy. The hip belt should sit comfortably on top of my hip bones, transferring the majority of the pack’s weight to my hips, and the shoulder straps should hug my shoulders without gaping or digging in.
After fit, I look at the features that make life on the trail easier. A good suspension system with a solid frame (internal or external) is non-negotiable for heavy loads. Ventilation is another big one for me; a trampoline-style suspended mesh backpanel can make a huge difference in keeping my back from getting sweaty. I also check for easy access. A front “shovel” pocket is perfect for stashing a rain jacket, and a sleeping bag compartment at the bottom is great for organization. Side pockets that can hold a water bottle while I’m walking are a must, and I love it when they’re angled for easier access. Finally, I consider the material. Robust fabrics like nylon with a high denier count will stand up to abrasion from rocks and logs much better than lighter, more delicate materials. When I’m putting together my own 10 Top Hiking Backpacks Guide: Best for Multi-Day Trips, these are the core features I’m always evaluating to ensure I can carry everything I need comfortably and efficiently.
Frequently Asked Questions
What size backpack do I need for a 3-day hike?
For a typical three-day, two-night summer trip, a pack in the 50 to 65-liter range is usually perfect. This gives you enough space for a tent, sleeping bag, pad, cook kit, food, and a change of clothes. If your gear is particularly bulky or you’re hiking in colder conditions where you need more insulation, you might want to lean toward the larger end of that range. It’s always a good idea to lay out all your gear first to get a visual sense of the volume you require.
How should a multi-day hiking backpack fit?
A proper fit is everything. First, the hip belt should wrap snugly around the top of your hip bones, not your waist. This is where the pack’s weight should be carried. The shoulder straps should feel comfortable and secure without taking the full load. You should be able to slide a hand between the strap and your shoulder. The load lifter straps (at the top of your shoulders) should angle back at about 45 degrees to pull the weight closer to your body. Finally, the sternum strap should be positioned to keep the shoulder straps in place without restricting your breathing.
What is the difference between an internal and external frame pack?
Internal frame packs are the modern standard for most multi-day hiking. The frame is built into the pack’s structure, keeping the load close to your back for better balance and stability, especially on uneven terrain. External frame packs have a visible, rigid frame on the outside. They excel at carrying very heavy, bulky loads (think hunting or trail maintenance) and often have better ventilation, but they can feel top-heavy and less nimble on technical trails. For the vast majority of multi-day hikers, an internal frame is the way to go.
How much should my packed backpack weigh?
This is a classic question with no single answer, as it depends on your size, strength, and experience. A common guideline is to aim for a total pack weight (including food and water) that is no more than 20% of your body weight. So, if you weigh 150 pounds, try to keep your pack under 30 pounds. With ultralight gear, experienced hikers often get this down to 10-15% of their body weight. The real goal is to carry as little as possible while still being safe and comfortable.
Are expensive hiking backpacks worth the money?
Generally, yes. A higher price tag usually gets you better materials, more durable construction, and a more sophisticated suspension system. This translates directly to comfort under load and longevity. A cheap pack with a poor suspension will feel heavy and uncomfortable no matter what you put in it. That said, you don’t always need the most expensive model. Look for a well-regarded pack from a reputable brand that fits you correctly. It’s the most important piece of gear you’ll own for your multi-day adventures, and a quality pack from a solid 10 Top Hiking Backpacks Guide: Best for Multi-Day Trips will serve you well for many years and countless miles.
