Prox Aluminum Backpack Frame, Size M, Black

Thank you for looking. I purchased this several years ago to pick up branches in the nearby mountains after installing a wood-burning stove at home, but I never used it and kept it stored in an indoor storage room. It is brand new and unused.
Although several years have passed, it has been stored away from the outside air, so there is no sign of hydrolysis on the belt or plastic parts.
Would this be useful for someone planning to use it for fishing or other outdoor activities?
