I wanted some lightweight but warm pants for nights in the tent or hut (NZ). These are perfect and I like how the waistband is flat instead of gathered and bulky. They say they have extra room for layers underneath, which is great for thermals, and it's true but it means they fit a little large - if you want them fitted, you might want to try a size down to compare. I'm a size 10 and very happy with the size 10, just a bit of extra room in the bum but I know it will still be comfortable even wearing them over another layer. Pricey but definitely good quality, warmth and weight matter for tramping and I'm very pleased with this addition to my pack :)
