[ I have purchased a half dozen Carhartt Base Force crew shirts. Yes, they 're expensive. Yes, they 're worth it. They keep me extraordinarily warm, and they 're very comfortable. They 're worth every penny you 'll spend. Buy one for your dad, too. He 'll appreciate it!

[ 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

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.

[ 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!

These Undergarments were a gift to my son. He wears them daily and he says they are great. They keep him warm and I 'm going to order more for him un the future. I would definitely recommend these to my other 3 sons and anyone else who is looking for the same type of clothing. Thank you Carhartt... excellence always!

Jag26
Like the feel of this LS tee. Can use it as a base layer or by itself on cooler days. I personally used it for an outdoor run and felt great. One thing though… while the fabric is intended to wick sweat out, I did notice the tee being soaked so not sure I ’ ll be taking it out for runs again. The length of the tee is also a little short so consider that if interested in this shirt.

Fredrick
[ This color is perfect, very beautiful and should be used again and again. Ideal light weight garment for fitness. Very breathable.

The Greek
[ This is one of two or three of the most amazing clothes I have. Technically it's a base layer but it's something I wear almost anywhere with the right pants and shoes. It's wool, but it's incredibly soft and comfortable. It works great as a base layer, but it's versatile.

[ I am getting synthetic products out of my wardrobe and I have become addicted to Icebreaker long sleeve layering shirts. They are extremely comfortable, come in a variety of nice colors and weights, so are quickly replaced my synthetic top layers.

I bought this for my teen to use as a base layer for skiing and sledding. It kept him dry and warm and fit him well. I bought a duofold base later too too and liked the duo fold a little better as far as stitch quality and material quality and the duofold material seemed a little thicker but I ’ m keeping this one too.

I bought this baselayer to use for my recent snowboarding trip. The weather was windy and 8 degrees each day. I already owned the baselayer pants which were military issued. This top was perfect. It kept me warm for 3 days. All I used was the baselayer and a hoodie with my ski shell over the top. Perfect setup all day long.

Like most Smartwool products I have purchased, this one is a nice weight, completely soft and comfortable AND attractive. I get compliments on it all the time.

Super comfortable first wear while on a 2 day backpacking trip. It made a great base layer and then when temps when up it was nice on its own. And a layer of sun protection with long sleeves! Odor control was evident, but control being the key word-- definitely not absent. I recommend this shirt and look forward to using again on the next hike and for my trip to the Tetons next month( as well as trying as a base layer for snow skiing!).

Perfect base layer for Spring in the mountains. Not too light, not too heavy, just right.

Thunderbolt417
[ I 've long been an unabashed devotee of all Smartwool products but their base layers, like the classic all- season merino long sleeve shirt, is truly the best money can buy. Since my days of living in the frigid mountains of northern Utah, I 've discovered the breathability of Smartwool's all- season merino long sleeve base layer makes it both the perfect shirt for keeping warm on winter's coldest days as well as ideal workout apparel. Smartwool base layers also make the best all- season pajamas imaginable. The all- season merino long sleeve shirt feels like a gentle hug when you slip it on, and remains comfortable until you 've completed your workout — whether it be a 3- mile hike in the frigid cold or a home gym weight training session. Smartwool has long been the gold standard for merino wool apparel. When you purchase your first Smartwool product, you 'll understand why.

I started with the Action Heat socks, and had to add the base layer to my collection. It ’s just the right amount of heat in the right places to make cold winter hunting trips much more enjoyable. I highly recommend the heated base layer for anyone that spends time outdoors in the winter.

Motorcycle C.
I got this primarily for motorcycling in colder weather. It works great. I can wear this with my jacket and jacket liner and I do n't have to wear other layers. I 've only used it so far riding in 50 degree weather but it was warm enough I had to turn it down or off. I usually wear a large but wanted it to fit tighter so I got a medium. The medium fits great. I would say the medium fits me perfect where normally I would wear a large t- shirt or long sleeve. Not too tight but not loose. Have n't had long enough to know how long the battery would last but have used it for a couple hours switching between high and medium and still have battery left. Would definitely use while skiing, etc
