I live on a lake and really enjoy kayaking. I am not a very dry kayaker and I always want to take pictures but never wanted to take my phone with me. I now take my phone with me and it stays perfectly dry. I have taken amazing pictures. Now I take this bag with me out on the boat to keep any item I want to stay dry while we're swimming in the middle of the lake. I have not run into any issues with this bag. I have not submerged the bag but it has definately been in standing water.
