These are REALLY comfy.  I like how you can pull them closed at the knee. There is a small, useless pocket on the butt.
They are lined, and very, VERY stretchy but they stayed in place in and out of the water.  I felt comfortable in them.  I purchased a cheap pair of these prior from amazon and they slid down my butt and it was VERY frustrating trying to run around the water park with my kid, constantly yanking them up.  So those are gardening pants now. ;)

I checked around and this is a great price for a nicer pair of lined swim capris, and they washed up beautifully.  No complaints.
