The Smartwool NTS bottoms are the only long underwear that not only keeps you warm but isn't too stuffy. Most long underwear is a polyester blend which traps all the air in and makes you feel uncomfortable after about a half hour. These wool bottoms breath so nice that you can wear them for long periods without getting uncomfortable. Thank you Smartwool for another quality product. Worth every penny.
