I was looking for a heavy weight version of sweat pants. Please note when I say 'weight' I mean thickness of material.  The product details indicated a weight of 13.6 ounces, which was about 50% heavier than other pants I found online at Amazon.  Unfortunately these are very light, probably best for summer use.  I have a pair from Champion which are about 3 times heavier than these.  I selected a medium size but after trying them on I should have gone with small.  These pants are huge.  I would have sent them back but I already washed them.  I threw them in the dryer at a high heat hoping that they would shrink significantly.  Although they did shrink they'll still about a size large.  Maybe a few more times washing and drying will do the trick. On the plus side they are comfortable and will be good for warmer weather.
