    Very comfy!

    The leg holes are a little large but true to size otherwise. Extremely comfortable.

    Happy but fits big

    I ordered a few different items all the same size, but these fit the largest and I might consider sizing down if purchasing again.

    So disappointed

    They were on sale so I ordered two. These are just.. not well designed. I bought an XL which was both too big and too small. They are too short lengthwise, but also too wide, with gaps around the legs and in the front and back. But had I sized down I likely wouldn't have been able to get them on. The inner part has almost no elasticity and does not create a seal- it has almost no structure. It seemed inevitable (and it was) that when I laid down, there would be leaks around the sides. I have a heavy-ish flow that is manageable with a nighttime pad. I bought these to save money on pads. They are washed and one is used so they are not returnable. I woke up this morning a complete mess and I am out almost a hundred bucks. I am very unhappy with this purchase.
