Patagonia Provisions Miir 32oz. Purchased new several years ago and used only once. It has been stored on a shelf since then. This model is no longer sold. Although I believe there are no issues with use based on my amateur inspection, please understand that this is a "used" item that has been "stored on a shelf by an amateur" before purchasing. No claims and no returns are the general rule. I will not negotiate on price. Immediate purchase is welcome.
