I bought this Dry Sack in size XXL for my son to go camping with his troop in New Hampshire for the weekend. I am so glad I bought this for him to put his sleeping bag in. The entire weekend they had torrential rain and no sun. My son said that he was so glad that I bought it for him because when they went hiking from campsite to campsite, this dry sack kept his sleeping bag completely dry. The XXL sack was perfect because he was also able to put a few other things in with the sleeping bag. He likes the way the top folds over and attaches. You can easily pick up the top, because when folded over it acts like a handle. Very highly recommended. I am going to buy a few other XXL Dry Sacks for his scout camp this summer.
