Best Overall
The Osprey Atmos Backpacking Backpack (Medium) earns its place as our pick for “Best Overall” thanks to its thoughtful design, excellent performance, and incredible versatility. Whether you’re a weekend warrior or preparing for an extended multi-day trek, this pack delivers in spades while remaining reasonably priced for its feature set. Renowned for its all-day comfort, durable materials, and ample storage capacity, the Atmos stands as an enduring favorite among seasoned backpackers and first-timers alike. With a balance of quality craftsmanship and user-friendly features, it’s a pack you can rely on for years to come.
Pros
- Exceptional Comfort: The AntiGravity™ suspension system feels like it molds to your body, offering unmatched support for long-haul treks.
- Spacious and Well-Organized: With 65 liters of capacity, the Atmos offers ample room for gear, while cleverly designed pockets and storage access points keep your essentials within reach.
- Built to Last: Osprey’s high-quality materials (including ripstop nylon) ensure this pack can take a beating on rugged trails without succumbing to wear and tear.
Cons
- Heavier Build: At approximately five pounds (medium size), this pack is heavier compared to minimalist backpacking options.
- Pricey for Beginners: While it’s worth every penny for serious backpackers, the price might deter those new to the activity.
Key Features
- AntiGravity™ Suspension System: Innovative back panel and hip belt design minimizes pressure points, delivering superior comfort for longer hikes. The pack feels weightless, even when fully loaded with gear.
- Adjustable Fit-On-The-Fly™ Hip Belt: Customizable hip support ensures maximum comfort across a range of body types, allowing for a personalized carry.
- Integrated Rain Cover: Built-in weather resistance ensures your gear stays safe and dry when the skies open up, making it a great companion for unpredictable conditions.
- Dual Access Points: Both top-loading and front-zippered access give you multiple ways to reach your gear in a hurry without emptying the entire pack.
- Reservoir Sleeve: Hydration compatibility allows you to efficiently incorporate a water bladder, keeping hydration easy and accessible on the move.
Why Did We Pick It
The Osprey Atmos stands out as the best in its category because of its outstanding balance of comfort, capacity, and longevity. During our field tests, it scored an impressive 8 out of 10 for comfort, thanks to its proprietary AntiGravity™ suspension system. When you’re logging endless miles on rugged trails, this system makes a noticeable difference in how fresh you feel by day’s end. The pack adjusts seamlessly, adding a layer of customization that’s hard to beat.
Durability is also a standout feature, scoring a respectable 7 out of 10 in our tests. Constructed with high-quality ripstop nylon, the Atmos packs in years of reliability, even with frequent use in challenging terrain. Trails with jagged rocks, dense brush, and variable weather are no match for this pack’s rugged materials. Plus, the integrated rain cover ensures gear protection during rain showers, giving the Atmos a leg up in weather resilience, where it scored 7 out of 10.
Its generous 65-liter capacity is a dream for backpacking enthusiasts who need to haul everything from camp stoves to sleeping bags with ease. Scoring a stellar 9 out of 10 for capacity, we found plenty of room for multi-day trips without compromising organizational features. Strategic compression straps and access points eliminate “gear dumping,” making this pack as functional as it is spacious. If you’re after a dependable pack that checks all the boxes, the Atmos is hard to beat.
Who It’s For
Buy It If
You’re the type of hiker who prioritizes comfort and capacity on the trail. The Atmos is perfect for individuals embarking on multi-day excursions or tackling terrain that demands a reliable, well-crafted pack. It’s especially ideal for people who invest in gear for the long haul, offering superior support, unbeatable organizational features, and rugged reliability designed to handle years of outdoor adventures.
Don’t Buy It If
You prefer ultralight backpacking or need a minimal, stripped-down setup to shave ounces off your haul. At five pounds, the Atmos skews heavier than its ultralight counterparts, making it less appealing for fastpackers or thru-hikers counting every gram. Budget-conscious newcomers may also want to start with a less costly option before committing to a higher-end bag like this one.

Why Did We Pick It
What stands out most about the Teton Sports Ultralight Internal Backpack is its value-to-quality ratio. Rarely in the world of outdoor gear do you find a product that performs this well for such an accessible price. With solid ratings in critical categories like durability and capacity (8 each), this backpack offers many of the same features as pricier models, allowing beginners or budget-limited hikers to enjoy a mountain-ready bag.
While it might not top the charts in comfort (receiving a 7), its adjustability ensures enough versatility to accommodate different builds. For example, during testing, we found that the adjustable torso length and waist belt allowed hikers ranging from petite to tall to comfortably carry loads of up to 5 pounds. This built-in flexibility makes it a winner for those who share gear or use it in varying conditions.
The lightweight build and efficient storage design were additional highlights. At just 4.5 pounds, it balances weight with functional features, making it ideal for multi-day treks without adding strain. Combine this with its above-average weather resistance rating of 6, and you get a pack capable of handling sudden downpours or drizzles without a hitch. While it’s not for monsoon-level conditions, the pack provides enough protection for most weekend warriors and moderate backpackers.
Who It’s For
Buy If
The Teton Sports Ultralight is perfect for budget-conscious adventurers looking for a reliable, feature-packed backpack that won’t empty their wallets. It’s great for someone dipping their toes into backpacking or weekend trekkers who need a practical, versatile option. It’s also an excellent choice for hikers who value lightweight design and solid capacity without venturing into high-end, expensive gear.
Don’t Buy If
This pack might not be the best fit for serious mountaineers or backpackers tackling extreme environments or weather conditions. Its moderate comfort and basic weather-resistance ratings mean it’s better suited for casual or intermediate trips rather than high-stakes expeditions. Additionally, if you prioritize ultra-padded comfort, you might find the support system here a bit underwhelming compared to premium models.
