Osprey has been a leading brand in backpacks since 1974. They make some of the highest quality bag available. Their two best and most popular bags on the market right now are the Osprey Atmos 65 (ad) and the Osprey Aether 70 (ad) (read our review here).

In this article, we are going to review the Atmos (ad), which is the more flexible bag of the two. The Atmos is built for carrying small-to-medium weight loads and is for both general use and light hikes or camping trips. In contrast, the Aether is built for carrying heavier weights on multi-day backpacking, hiking, or camping trips. The Atmos comes in three colors, Red, Blue, and Black.

Size and Weight:

The Osprey Atmos 65 (ad) comes in three sizes; small, medium, and large. The small is 3 pounds, 6 ounces and is 62 Liters. The medium is 3 pounds, 9 ounces, and is 65 Liters. The large is 3 pounds, 10 ounces and is 68 liters. The strapping and suspension system for the bag is adjustable.


The bag is made of 210-denier twill nylon and 100-denier mini-ripstop nylon. These are top-of-the-line materials that are both lightweight and durable. They should last for a long time and can take a beating. People often gush about the Osprey bags straps and backing, which is a mesh like materials that is comfortable but also basically does not get wet. When it does get wet, it drys very fast. The bag is sewn very well. The stitching doesn’t fray like in cheaper bags.

Why It’s Awesome:

Besides the previously covered facts that this bag is decent size, lightweight, made of high quality materials, and has fast drying backing and straps, the Osprey Atmos is also awesome because of the great Osprey Suspension system. The system is very comfortable and holds the bag tight to your body and evenly distributes the weight. The straps can be adjusted in several ways and there is a fit-on-the-fly waist belt that molds to you when heated. The AirSpeed suspension with LightWire frame and 3D tensioned backpanel provides support and balance. The comfort in Osprey bags compared to some others, like North Face, is absolutely amazing.

Some other features of the bag are a spot for a hydration pack (so you can carry water in your bag and drink through a hose), there is a tool attachment spot, a spot for a sleeping bag, a spot to attach a tent to the bottom, and a removable top pocket.

What Could Be Better:

The one negative of Osprey bags is the high price. You are paying for quality, but there are similar bags without the name brand that go for $100 or more less.


This is a great bag for someone who wants a name brand hiking bag or general use backpack. It can be used for heavy duty backpacking as well (as in 2-3 day camping trips in the wild), but if that is what you intend you may want to just upgrade to the Aether 70 (ad) for a little more cost as it is bigger and built for heavier loads. You can purchase the Osprey Atmos here (ad).
