Every model of Atom Packs backpack will come with a sternum strap which is now sewn into the daisy-chain webbing. 

  • Whether you like yours high or low, getting a comfortable fit is important. Take the time to try out a few different heights by sliding the strap up and down on the webbing. 
  • The strap is designed to offer some support and prevent the shoulder straps from working their way outwards as you hike. The elastic means you have a small amount of flex in this strap to allow your chest to expand and contract as you breathe.
  • The strap buckle incorporates a whistle.

Here's a quick guide:

The sternum strap connects to the backpack by attaching onto the shoulder strap daisy chain - this is located under your shoulder pocket, where fitted.
