I wear these ski touring and they keep me warm on really cold snowy days. I love them! They might be a little too warm for touring on blue bird days.
I also wear them on my resort days and they keep me warm all day long.

I am 5'5" and wear size 4 pants so I ordered small. It still is big for me (on the calf-area) but my husband says that maybe it will shrink a little after washing.

Other than that, this is perfect. Unlike others, the waist doesn't go as high as your ribs so you can still wear this under your low-rise jeans. The fabric is soft and smooth and my silly hubby thinks it's sexy. ;) It is warm and comfortable. Highly recommended!

Patagonia Capilene Bottoms are superior to any other base layer I own. I love Smartwool, but the wool is too thin and snags easily, especially as a bottom. Capilene is durable, and doesn't stretch out nearly as rapidly as wool bottoms. You can wear them for multiple days in a row without needing a quick rinse, and they look amazing. I wear them casually all around town, and if you're looking for thick leggings that you can't see through...these are your best bet! They're incredibly comfortable, and are perfect for almost any aerobic activity. I use them at the gym, as well as hiking, skiing, working and just lounging around the pad. They're toasty through Aspen winters, but don't make you sweat. A definite must have in my book!

These are amazing. I've owned long underwear too thick, too thin, too big, too tight, too wrong. These are absolutely perfect. Living in Northern Minnesota they fit the bill as something to wear underneath jeans, snow pants, cords, anything. I wear them walking to school/work, and they are comfortable to wear all day long without getting too warm. Walking the dog = perfect. X-ctry skiing = maybe too warm (but I have lined snow pants) I generally wear size 4-6 pants, size small in these are just right. Added bonus = fabulous plum color.

Very comfortable, I cannot even feel that I am wearing them, and they definitely keep me warm all day.
I usually wear under ski pants and it doesn't make you look bigger...

Waist sits a bit high, not for lower-rise women's pants. The review I read saying it's low-rise probably refers to the older version that is darker blue. Also, not very stretchy, so I feel a bit immobile and there's lots of friction when putting on or removing pants over it. Otherwise, really warm and breathable and high quality. I wear them everyday.

Love them...wore on a cool day for a long hike...not too warm, no sweat build-up, stayed warm in the wind when stopped for the views.

These are great - they do get warm with significant aerobic activity. But they are the perfect layer for hiking. Allows you to go with a soft shell pant and stay plenty warm (even down to 29 degrees with some wind) like today.

I wore these pants as my baselayer under my (very) thin hiking pants for backpacking in Haleakala Volcano, in Maui. We were pretty much above 6000 feet all the time, and when then sun went down, the temperature was around 40 F, but the pants kept me warm during the whole trip. They are not just warm but also very comfortable. I got for my money exactly what I wanted.

Capilene 3 tops/bottoms for women make a perfect base layer for outdoor and even indoor wear when temperatures are forty and below. I had to work hard to find the L/XL sizes. With them I don't have to worry about feeling cold any more. They wash fine in cold water, and dry quickly on a hanger. Don't want to ruin them in a dryer. Owning two sets saves me from buying extra outer layer clothing. Thanks to Patagonia for making them, and for Backcountry.com for their terrific sale price.
