Thank you for looking. I purchased this new over 10 years ago, used it only a few times, and then stored it at home for a long time without using it. The approximate dimensions of the bag are: height 400mm x width 350mm, and bottom width 240mm. The top has buttons on both sides and Velcro, so it can be securely closed. How about using it for waders, wet items, etc.? Considering its age, the construction and material feel quite sturdy. Please check the photos carefully for details on the condition and dimensions. I will pack it as compactly as possible for shipping, so please understand that there may be creases. Thank you.
