I bought for nordic and light backcountry skiing in Colorado. They fit athletic, but are as comfortable as my favorite jeans and I could work in them or wear them all-day. They shed water, are breathable, and on colder days I wear a base layer underneath. I do require a nylon web belt with mine. The built-in gaiter doesnt have any clips and are a bit large (for tele or nordic boots). The reinforced knees are perfect, especially nice with telekenis knee-pads. These pants will be my Spring alpine ski pants as well. Nice job Marmot!
