Thank you! This is a Patagonia Refugio 28L backpack! The exterior shows signs of use, but the interior is clean. It's a convenient 28L size. As expected from Patagonia, it's comfortable and reduces fatigue. Please understand that this is a used item. No claims and no returns, please. I do not reserve items according to Mercari rules. The person who presses the purchase button first will be given priority in any case. Hope it reaches someone who needs it!
