Osprey Atmos AG Review

Why Should You Consider the Atmos AG 

Comfort

What makes the Osprey Atmos and Aura stand out is the broad, spacious Anti-Gravity mesh back paneling. The open mesh back panel lets air circulate without compromising on structure. It’s nearly seamless, eliminating common pressure points and relieving tension from your back. Even if your bag is loaded with climbing gear, a sleeping bag, and other camping equipment, it won’t feel as heavy. 

Since the single back paneling mesh extends to the hip belt, the bag evenly distributes weight on the hips, and the construction moves with your body. It feels like the bag is hugging your body, rather than you’re lugging it on your back. 

Fit

Since the pack comes in three different sizes, you can find the best one for your frame. The well-padded shoulder straps can be adjusted on the go and give around 10 cm of vertical range. The hip belt can also be adjusted on the fly with velcro fins; it conforms precisely to your shape with 15 cm of adjustment. Regardless of your body size, the Osprey Atmos or Aura will fit comfortably. 

For another way to dial in the fit, you can move the shoulder harness up and down along the track. This supports pack weight above the shoulder line so the load doesn’t feel top-heavy. The slidable stiffener also gives the shoulder straps more structure without being too rigid. 

Ventilation

Thanks to the AG system, sweaty discomfort is ruled out even on warmer hikes. Since it’s made of a continuous piece of breathable mesh, sweat easily passes through the material, keeping you cool. You’ll be amazed at how breezy you feel while hiking thanks to the pack’s construction. 

Access & Compartments

If you’ve ever owned a hiking backpack, you know the headache that comes with being disorganized. One of the best parts about the Atmos and Aura is the multitude of separate pockets and compartments. There are stretch mesh side pockets where you can place a water bottle or spare gear. There are also front stretch pockets with a drain that is perfect for storing wet clothes. 

If you don’t need as much space, the removable lid on top of the bag can be left at home or in your tent. The bag also features a separate sleeping bag compartment and removable sleeping bag straps, as well as a nifty Stow-on-the-go trekking pole attachment. There are also upper and lower compression straps and bungee loops to latch gear to the outside of the pack. 

Durability

You’ll find reinforced materials along the top and bottom of the hip belt with thicker mesh on the top for durability. There are also two sturdy pads on the bottom of the bag which protect its frame. The stretchy, malleable exoshell material hugs your body and is durable for challenging use. There’s also solid paneling in the front stretch pockets to protect from rips and tears. 

Weight

Averaging around 2 kg, the Osprey Atmos and Aura AG are incredibly lightweight. The bag itself won’t add much extra weight to your load. Here are the specific weights for each respective model: 

• The Aura 50L bag weighs 1.82 kg for Extra Small, 1.86 kg for Small, and 1.9 kg for Medium. 
• The Aura 65L weighs 1.92 kg for Extra Small, 1.96 kg for Small, and 2.01 kg for Medium. 
• The Atmos 50L weighs 1.79 kg for Small, 1.8 kg for Medium, and 1.8 kg for Large. 
• The Atmos 65L weighs 2.04 kg for Small, 2.07 for Medium, and 2.10 for Large. 

Overall, the weight of the bag is incredibly impressive considering all of its features and compartments. For the amazing comfort it provides, we feel like it comes at a great weight. Although it isn’t the lightest pack on the market, the innovative suspensive system that can carry over 20 kg makes up for it.
