I've searched high and low for a product that has these simple qualities.Do you like to put bags inside of bags? I do. That makes this the perfect product for me. I put all of my wet shower stuff in here and hang it in the gym shower.1. good air flow. I wipe my bottles down after using in the shower but they are always a little damp. When I get home I just pull this bag out and hang it overnight to make sure everything dries out and then back in my gym bag they go.2. Like the handle on the bag. I've tried similar bags without the handle and it ends up being annoying. I like being able to both carry and hang the bag from the handle.3. see through mesh. In addition to the air flow I like the visibility of what's in the bag. It helps that I can see that I have remembered all the things that belong in the wet shower bag.4. small and compressible. This bag is soft mesh. It does not take up much room - this is an important feature for me as I shove it inside of another bag.I don't know how durable it is but I am happy with this product and I'd buy it again.Just bought a second one. This thing is super great.
