Rated 5 out of 5 by from Arctic Circle I am an oil field worker on the Alaskan north slope. For anyone who doesn't know where that is it's 250miles north of the arctic circle. Sometimes it gets as low as -60 ambient with the wind chill in the -80's. I have tried many layering options through out the years and have come to swear by merino wool. I own several of these base layer tops and bottoms because nothing else allows me to remain as warm as I do while still being able to wear the minimum amount of layering so I can maintain mobility while I work. I wear them while I'm mountaineering in Washington, drift fishing the Kenai river here in Alaska, flying my supercub around the glaciers up here and skiing in Utah with my family. These are all worth the price! I promise you will not regret your purchase when you are toasty warm wearing surprisingly very little. Go ahead make the purchase! You can thank me later.

Rated 5 out of 5 by from Very Satisfied with this Base Layer I have several of these Smart Wool 250s to include some zip styles. I have been extremely satisfied with these shirts. I wear them next to my skin with an additional layer or two depending on how cold and the weather may be here in Colorado. I do not ski or snowboard, however, these shirts work great in removing snow from my area, hiking, ice fishing or those cold morning walks. I wash these shirts (inside out) in cold water. I do not wash them with other fabrics like cotton, rayon, etc. These non wool fabrics tend to "roughen up" the wool fabric garments. No fabric softener because it impacts on the wool fabric's ability to wick moisture. After washing, I immediately put the shirts in the dryer and set to Air Dry Only for 30 minutes. No heat. The shirts will still be damp after removing from the dryer. I hang them to air dry (inside out). Sounds like a lot of work but it's not considering the cost of these shirts. These steps have actually prevented my shirts from pilling. Some reviews regarding these garments have disclosed pilling, however, I have not encountered pilling on any of my Smart Wool products. I hope this helps someone.

Rated 5 out of 5 by from None Better for Cold Weather Base Layering I own several Smart Wool products. Their products are pricey, however, in my opinion, you're getting the best fabric technology has to offer. These garments are made from Merino Wool. For me personally, there is no itchy, scratchy, wool feel. Seriously, they fell like cashmere next to your skin. My favorite Merino Wool Weight is 250. It is the perfect fabric weight for Colorado winters. The wool fabric does a great job wicking moisture from your body during increased activity in the winter outdoors. I am not a skier or mountaineer, however, when walking, hiking or manually removing snow, I wear this garment as a base layer. I use to wear cotton next to my skin and after some winter outdoor activity, I would sweat and subsequently become cold and clammy. These shirts wick that sweat away and you still feel warm. Great fabric technology. I have found none better than Smart Wool.

Rated 3 out of 5 by from Warm, fitting but... My next purchase will probably be a wool mix. After a few extended backpacking trips and wash cycles., My concern is long gevity as it feels it's losing its hold

Rated 5 out of 5 by from Great Shirt My son bought a shirt like this from you when he was a hotshot firefighter about 6 years ago. He wore them even after sparks from fires burnt holes in them. When I met him to hike in the wilderness this last summer he was wearing the same shirts with holes. He said he loved them and wished he had new ones but until then he would never get rid of the old ones. I bought him new shirts for Christmas and he loved them. Great purchase.

Rated 5 out of 5 by from Awesome!!! I'm a 5'11", 195 female, with an average torso, who prefers to wear Men's Smartwool tops to women's due to the longer length available. Therefore, I wear a men's M. I do have a women's XL in this top but it's just too short. I'm always cold and have fallen in love with Smartwool because of the super products they create. I have this top which zips up the front and a few days before my trip to Alaska I decided to take a chance and order another top. I wasn't sure if it would arrive on time but it actually arrived the next day which was super impressive and amazing. Thanks REI! I was packrafting in Alaska and needed a midweight top and bottom to wear under my drysuit. I had two sets of Smartwool NTS 250 tops and bottoms and wore them the entire time due to temps being in the mid to low 60's and dropping to low 50's/high 40's at night. There were two days when I had to wear both sets together because of the temp of the glacial water. I also had 4 pair of Smartwool trekking socks along with me and 1 pair of Smartwool running socks to wear at BaseCamp and on the plane. I can't say enough about Smartwool. First the socks, tops and bottoms kept me super warm even if they got wet. They held onto their form and did not stretch. They were not picky and even on the warmer days did not cause me to over heat. They did not have an odor and trust me I was not able to shower for 7 days, so... Even if you can't find Smartwool on sale know that you are purchasing something that is made to last. Worth every penny!

Rated 5 out of 5 by from Super Comfy Really enjoy the material and anti-chafing. Extremely comfortable as a single layer in cooler weather. Will be putting some wear on it through this winter with some cross country travel. Looking forward to how well it holds up.

Rated 5 out of 5 by from Yes 165 lb 5'10" size M fits perfect for casual wear...snug-loose would be a good word to describe it. A woman asked me where she could find one to buy for her brother the first day I wore it.

What does "NTS" stand for? Is this the same product as this , except with a pattern?

Asked by: mtbakerstu
​NTS stands for Next to Skin. The 250 and the mid-weight tops are very similar. The weight and warmth is comparable.
