I bought these for my husband for our New Zealand trip. I used the size chart to determine what size to buy. My husband is 5ft 10' and uses a size 32/33 waist with 30 in length, so I went with the large. Unfortunately it was a bit too big for him around the waist and since our trip is a few days soon, we will have to make do. He will be using a belt to make it fit. Its quite puffy of course given the fact that it is snow pants and it makes his legs look unusually bigger than normal which i find amusing. The fabric seems durable for snow and the inside fabric is soft and warm. We will be testing it out in cold/snowy weather and i will update on how it was.
