Will not likely wear before the fall season, but it seems perfect for skiing- light fabric for packing, but plenty of thermal warmth. The color was lovely too- subtle rose!![ for layering... sleeves were not super long, so not need to stuff under your jacket.] Would also come in handy alone for fall golf! Also a great name for teens- I got one for my 16 yo granddaughter as well.

[ Carthatt is a quality brand that is made affordable. I used this for my snow trip and it gave me warmth so I do n't have to layer too much. Very satisfied with my purchase!
5
Bobby
[ I knew I was getting a good shirt because this is my second one. It fits snug enough to keep out the wind. It wicks and dries like an athletic shirt. Since it is 100% polyester, it is likely more durable than most. It keeps its shape and looks better than most.
5
BD592
[ Best value for your money as far as base layers go. You can spend 3x more on Smartwool or Icebreaker if you are looking for the best with a hefty price tag. Overall, this lives up to Carhartt ’s name

You don ’ t realize how much you need a heated base layer until you have one! It ’s been such a benefit to various aspects of my life. I wear it beneath my layers when spending time outdoors during winter in Wisconsin. But I ’ ve also worn it to work( in an office) during especially cold days. It fits true to size and is comfy. Somehow it seems to trap heat inside yet it ’s also breathable, I don ’ t sweat in it like I have with other base layers.
5
The Base Layer Shirt takes the bite out of any cold day! And the battery last for hours! Washed it in a cold wash then hung it to dry, easy peesey! Definitely worth it!
5
I bought the base layer for my son who works at Disneyland in Anaheim Ca. and he loves it. Keeps hos 3X body warm when working nights. Great product

Just wearing the shirt and not on has been enough to keep me warm. The few times I have used the heat, I set it on lthe lowest setting and was plenty warm.

Definitely worth having extra battery banks if you ’ re skiing all day or anything like that, also could use an extra hole in the battery pouch so you can route the cable to a pant pocket more easily. Besides that, it definitely lasts through the wash and multiple winters

Shirts are well made and comfortable. But I preferred the ones from the previous season. Not crazy about elastic thumb bands, they dig into thumb webbing on your hand. They were much more comfortable with the slash cuff thumb hole

5
MehganM
Love the deep purple, top base layer! It fit really well and was long enough despite my 5' 11 '' height. If you are a C cup or bigger, you might want to size up, but for anything smaller it should work. It's odd that this was long enough but the matching pants are not as I 'm very proportional. In any event, I 'm grateful to have this top and I love the feminine color! Thank you!

[ Bought one in wine and two in black. The wine fit perfectly but the two black ones were tight under the arm, so I returned them. Quality is terrific and it was well appreciated in the cold Montana winds last month.
