Padded arm sleeves for extra comfort, and helps with washing just this, instead of your pack. Note that the Double Barrel pack comes with them already, the single does not. It's rare that people use this on the single as it rides very comfortably due to the little weight that it exhibits, but some do enjoy it! Check the video below for proper install tips.
I have the single barrel. It works fine without the straps but I really enjoy the extra padding for comfort and that you can wash them and not the whole pack.
I do a lot of running. Having the extra thick pads for my HydraQuivers on transcon-type running makes a big difference.
For the hydra quiver and gear quiver that do not come with padded underarm straps, these add a luxurious comfy feeling.
Exactly what I needed, without having to rig up something on my own. The padding is just enough to take some of the pressure off from the straps.
Excellent!
