This water proof roll top bag can be compressed and stored compactly. The classic "Water Proof" has been renewed using environmentally friendly materials since the 25S1 season. The functionality is retained with a strong water repellent and waterproof seam tape. By using a special material on the bottom, you can compress and deflate the air without running out of water. The bag itself is thin and lightweight, making it convenient to carry. Please note that if you store wet items, it is not completely waterproof. We recommend squeezing the water before storing. Useful for a variety of occasions, including pools, traveling, outdoor activities, and rainy days. Also available in 8L (Part Number: SE22515) with the same design and material. A handy item for swimmers
