Great Wool

I owned three of these shirts and have always loved them. I hike in them and they work well for starting cold and when the day warms up. I almost always just wear the shirt, sometimes with a wool sweater or light coat to start in especially crisp mornings. I've lost a good bit of weight and decided ... Read More

    Very nice product! Fits well, I don’t like my clothes to fit skin tight and this fits the bill. Not to tight but not too loose either. Sized correctly in my opinion. Have yet to try it out in cold weather, purchased for upcoming white water rafting trip for warmth and it’s quick drying attributes. Will update after my trip...
  • Great deal

    Fits comfortably, not too restrictive, perfect weight for a little warmth under a t-shirt or more warmth as a base layer for a winter bike ride
  • Excellent Brand, Excellent Price

    Thanks Sierra Trading Post for offering SmartWool and especially the sales! I love SmartWool merino and I wear this shirt every time I get the chance because it is great quality and the most comfortable shirt I own. The shirt fits really well, you will not be disappointed with this purchase.

  • “is the fit on the SmartWool NTS 250 base layer top skin tight? I prefer a looser fit.”
    Asked by jeff from ohio on 11/10/2017 12:11:10 AM
    • I wear a medium but made a mistake and ordered a large and its loose so buy a bigger size if you want loose fit but its supposed to be tight

    • It's like the picture, it's (nicely) skin tight, physically it's a comfortable fit as it conforms so that it doesn't bunch under other clothing. But without anything over it, I am reminded that I want to get back into the gym...
