Good ski gear

These are for my husband to wear while skiing. Any type of skiing. They nicely stop above ski boot tops. No extra pinching. They are light but warm. A good layering garment. Smartwool will last days with no smell. Awesome!!

Light and warm

3/4 length works great for me at 5"6v. These are just like any smartwool product but this one seems more like a lightweight vs midweight baselayer. My tops over 200 feel thicker/heavier . . Still good enough for what I need but for colder days I prefer a heavier weight. Also rinds a bit large so I'm glad I went with a medium. . . most if my pants/...Read More

ut bunching up, and it provides full coverage around the calves without feeling too tight or restrictive. The waistband is soft yet snug, and it doesn’t dig in or slip down, which is always a plus. The Merino wool itself feels incredibly soft against the skin—no itchy irritation, which is a huge win for anyone who's had issues with lower-quality wool products.
Even in freezing temperatures, these bottoms kept my legs comfortably warm without making me overheat during active moments like hiking or skiing. The breathable fabric allows moisture to wick away efficiently, so you don’t end up with that uncomfortable sweaty feeling. Plus, Merino wool naturally regulates temperature, which kept me feeling just right throughout the day. Read Less

The perfect baselayer pant for skiing

This is exactly what my husband needed to keep his legs warm under his shell snow pants and mid layer pants for cold ski days. Good quality merino.

Smartwool 3/4 baselayer

Great baselayers, and the 3/4 length makes all the difference if you're like me and don't like to tuck it into your ski boot.
