Under ArmourMen’s Packaged Base 3.0 Long Sleeve Crew Neck

These are so warm and do what they advertise them to do which is make you feel like you have a second skin that is automatically warm, I would highly recommend if someone is working outside in the cold or playing outside it the cold. They are a little pricey but worth the money. We have purchased our whole crew one for the winter weather and they all love them

My husband is a southern boy that does not do well in the cold. He works outside and would not survive without the 3.0 base layer. He gets a new pair every year for Christmas and he has a collection because they last year after year. Great quality, all day comfort, we will continue to buy.

This under shirt does keep me warmer than a regular long-sleeve knit shirt. Not quite as warm as I was hoping, but should work for me. At first I ordered a size large, which is the size I wear. It was a bit tight. I exchanged it for XL, and am very happy with that. If you like a tighter fit, then order the size you normally wear. If you like a looser fit, I recommend ordering one size larger than normal.

Fit is a little slim. Very warm, perfect for outside activity.

Working outside and winters at -40, having this as a base layer keeps me warm all day. If you’re on the fence about buying this, DO IT. Pricey yes but you get what you pay for, don’t waste money buying cheaper. You will stay comfortable in this.

I am 5’11” and 165lbs. Chest: 38 Waist: 32.I got a size medium.Fit:The shirt is longer than normal to help prevent it from rising up when moving or bending down during activity! If it was shorter, then cold air would come in when bending over. I know someone reviewed the length of the shirt, and said that they hated how it looked, but it's longer on purpose. Regarding actual fit, I believe that the shirt is true to size. However, it is a bit tight on the armpit / chest region. This is because the shirt is a “fitted” style. Consult the size guide because it should be fine for most, but if you are on the larger side (chest) you might want to get a size up.Comfort:I know irritation is of concern for some people, but the shirt did not irritate and was rather comfortable. The material isn’t that rough on the skin, that being said don’t expect it to be silky smooth. Nonetheless, it should be perfectly fine for most people. The stitching near the shoulders can be a bit rough on the skin. Unnoticeable for the most part.Warmth:I bought this shirt to use when I go out to run in the winter. I wear this as a base and then layer it out with a jacket on top. It works fine for ~30 degrees temperature with a light layer. I don’t know how I would feel below 30 ish but it definitely helps, so I would recommend.Quality:This shirt is made of synthetic materials. It works great for working out and activity. Since it isn’t like merino wool, the material also lasts longer after washes and remain durable. The fabric feels pretty durable as well and considerably thick.Price:Very pricey. I know that base layers are considerably more expensive than normal shirts but the $70 is definitely a steep price to pay for a shirt. There may be cheaper alternatives that match the quality, but if you want to play it safe and value reliability, durability, consider getting this shirt.TDLR: Reliable base layer that is durable and helps maintain some warmth. Probably not goose down warm, but it helps. Bit tight on the chest, but still true to size in my opinion. May not "look" great considering its tight fit if not wearing something with it. On the pricey end if paying full price.

The UA baselayer is the best out there. I have several weights and wear them all winter long. They fit as advertised and keep you warm. You pay for what you get. They’re worth the expense. It’s like having an extra layer of skin, to keep you warm..

I build custom homes and when fall is right around the corner, it's under armour time. I saw them on here for like thirty some bucks. I got about 5 or 6 of them. In the store that would be 300 dollars, Amazon, less than 175.Ifeel this is one of under armours top products that keeps me coming back. The fit is always perfect. They are very warm for outside work. It's so cold that the compressor freezes up and the batteries won't hold a charge. These are mandatory!

This is probably the best baselayer around. It’s my second underarmour top and is to add to/replace my old underarmour top which I have had for ten seasons (maybe longer)The old top is less thick and I recall there was only one top and one set of leggings offered whereas now there are 4 different ratings. I have gone for #3Even the old top is still nice and warm and in shape but I wanted a step up to match up to my #3 leggings.I also have a merino wool base top but on balance I prefer my underarmour because of the gridded inside face that traps warm air against the skin.

mi è sembrata troppo larga e scollata, e la qualità non l'ho percepita.

best thermal Ive ever bought well worth it.so good i bought extras

Best base layer for cold winter weather. Feels light weight when wearing but keeps you warm when it cold out. Best choice you can make

Fits really nice kept me more while hunting
