Best Size Backpack for Backpacking

For backpacking, you want to buy a backpack that is fairly large for a long trip but also one that is lightweight and form-fitting so that it isn’t too much of a strain to carry when hiking and walking along a trail on weekend trips.

The Osprey Atmos AG 65 is the way to go when searching for backpacks for travel. It has everything you need in a backpack for this type of hiking. Backpacking isn’t usually an extremely strenuous activity; it’s just a lot of walking and sometimes camping. It’s one of the most popular types of hiking right now because of how enjoyable it is. People like to backpack on paths that have amazing views and vast landscapes that are very pleasing to look at, so don’t ruin the relaxation with the wrong type of backpack.

Here is a look at the bag, this is the Unity Blue color, but it also comes in Rigby Red or Abyss Grey. You can get it in 3 different sizes on Amazon-small, medium or large. The small size (62L) is best because it’s less weight to carry but if you are very tall then get medium or large so that it fits correctly compared to the length of your torso.

Below is a table showing the dimensions and specifications of each size and the prices of each.

Water Reservoir

Easy access to hydrating fluid is the most important feature you want to look for in a backpacking bag. Lots of walking depletes your hydration faster than anything else. Not all backpacks have a specially designed pocket for a water sleeve, that is why the Osprey Atmos AG 65 is the best bag to get for your money because it has one. It’s not the cheapest bag out there, as it’s priced at just under the $300 mark (size small) on Amazon, but it is most definitely worth spending the money on it.

There was clearly a lot of thought put into the making of the backpack, and it paid off because almost every customer review of it is completely positive. You can read more about the reviews of this product at the bottom of this article-even though there’s not much to see because of how little is wrong with the bag itself according to customers. If you decide to buy a cheaper backpack, you’re most likely sacrificing one or some important features that you would otherwise come to love in this bag.

Holding Straps for Trekking Poles

Sometimes you will use trekking poles to help you climb steep hills along the way, but when you’re walking on flat ground and no longer need to use them, a holding spot or elastic strap on the side of the backpack will help you to easily carry them around.

Lugging around trekking poles is not very fun. The Osprey Atmos has a place to hold them, and it works well according to the reviews made by other people who have used the backpack.

Specifications and Special Features

Backpacks made specifically for a backpacking trip, like this one, include specially designed features for that type of hiking. This backpack, for example, has a built-in hydration reservoir sleeve that holds up to 3L of liquid, which is great for backpacking because hydration is very important when it comes to the amount of cardio you will be doing.

It also has an anti-gravity suspension system, a LightWire-tensioned, full peripheral frame that comfortably transfers pack load, which makes the backpack feel much lighter than it really is. It features a fit-on-the-fly adjustable harness and hip belt that conform to your body, making it less noticeable that you have a backpack on. The main idea of this pack is to make your backpacking trip as enjoyable and efficient as possible without feeling the strain of heavy loads.

The designer clearly wanted it to feel weightless and unnoticeable for the user. It also has dual access stretch mesh side pockets which make it easy and convenient for you to reach for smaller items or gear and your water bottle so that you don’t have to waste time stopping on the trail.

It also features:

  • 210D high tenacity nylon (accent)
  • 420HD nylon packcloth (bottom)
  • Stow-on-the-go trekking pole attachment
  • Adjustable harness
  • Adjustable hip belt
  • Removable floating top lid with dual zippered pockets

Customer Comments

It was very highly-rated amongst customers who previously bought the backpack and hardly any complaints. According to those customers, this backpack fits best compared to other various brands that they’ve tried. It’s well-ventilated, and the netted support system that is in between your back and the bag itself makes it very comfortable to wear while hiking.

They also complimented the vast set of storage pockets, big and small because of how easy it was to organize their gear and other essential items. A small detail that bothered, but did not turn away, some customers was that the zippers on some pockets are slightly hard to open one-handed, which they said was irritating but did not change how much they loved the experience of using this bag. Another problem is that it doesn’t come with a bladder from Osprey for the water reservoir spot in the bag.

In Conclusion

If you’re planning on taking a backpacking trip soon, you need to find a backpack that suits your every need. The less amount of hassle it causes you, the better. Other hikers that have tried multiple different backpacks, rate the Osprey Atmos AG 65 as the best backpack to have for backpacking, specifically.

It features lightweight material and mesh fabric for good ventilation, which also makes it an extremely comfortable backpacking pack to wear. You won’t find much wrong with this bag at all. It even comes with a built-in hydration reservoir for convenience. It’s very functional.
