Similarities Between the Atmos 50 and the Atmos 65

The Atmos 50 and the Atmos 65 are very similar in the fact that they have most of the same features. Below are just some of the features that they have in common:

  • Antigravity suspension system:

    When wearing these backpacks, you feel like you are wearing the same weight with less impact. The suspension system makes you feel as though you are traveling lighter than usual due to its nifty design.

  • Floating top lid:

    The top lids of these backpacks are actually removable. This means that you can remove some of the weight from the backpack if you don’t need the extra top pocket. After you remove these lids, you can place the flapjacket over the top in order to protect the contents of your backpack. This flapjacket also doubles as a compression strap to keep the top portion of your content nice and tight. The flapjacket comes integrated into the backpack.

  • Ice pick attachments:

    Many people like to go ice climbing in the Winter with these backpacks. That is why Osprey has added ice pack attachments that are essentially bungee cords sewed into the size of the backpack.

  • Internal compression straps:

    In order to provide for extra compression for your gear, Osprey has added internal compression straps inside of these backpacks. Unlike some other backpacks of the same sort, the Atmos 50 and 65 have colored compression straps. They are a bright red hue so that they do not blend in within the rest of your gear.

  • Trekking pole attachments:

    You can attach trekking poles to the shoulder straps and hip belt of these backpacks. Trekking with poles has become a very popular activity, so a backpack would not be complete without this attachment.

  • Adjustable harness:

    The back harness of these backpacks, which is the main frame, is adjustable to your own torso length. This is one of the new features of the new Osprey backpacks, as it actually increases the chances that you will be comfortable with the size of backpack you chose.

  • Fit-on-the-fly hip belts:

    Fit on the fly hip belts allow you to adjust the length of your hip belt to accommodate various waist sizes. The ends of the hip belt have pads that extend 5 inches to accommodate for plenty of difference.
