This aluminum stay is part of the back panel support system for the Circuit pack. If you have broken, bent or somehow managed to lose your aluminum stay, this is the replacement part you’ll need to make it right.
To get the right sized aluminum stay for your Circuit, please select the correct size of your pack from the drop-down above. If you do not remember what sized Circuit you own, check the size tag. The size tag can be found in the seam along the top back of your pack, where the top compression strap meets the back panel. If your size tag is missing, you do not remember what size pack you ordered, and your pack fits correctly, use a measuring tape and the Torso Size Chart listed in the “Sizing” tab to find your pack size.
