I bought a pair of these from Amazon last fall to wear in the coming cooler mornings.
Yesterday, I received a second pair of the same that I ordered again from Amazon.
The first pair did not have the padded inner seat. The second pair did. The first pair (large) fit like a glove. The second pair was much larger. I decided to keep them, but, I removed the inner padded seat because that was too big for my rump. They just might be warmer in the coming cooler mornings because of the unintended vapor gap. I guess I will know when cooler weather arrives.
Meanwhile, I have two different pairs of cycling tights that fit like you'd expect tights to kit.
In the future, I guess I'll order from Performance Bike for this sort of product. I have a feeling that Amazon either received them wrong or picked the wrong product, but, they were marked the same as the first pair I ordered (same part number).
