perfect undershirt that keeps you cool and makes your white dress shirts even whiter without revealing a sleeve line.

For as much black in the shirt you'd think it makes you hot but the white on the back keeps you cool plus it's material is Adidas' take on Dri-Fit so it wicks away sweat/moisture making it perfect for any sport (preferably basketball of course).

I have some heavier undershirts from Calvin Klein, but they're a bit warm for summer wear.  These original Penguin undershirts by Munsingwear fit the bill perfectly for warmer-season wear (actually fine year-round).  Theyre well-constructed of 100% cotton  the only loose thread I found was on the cute penguin embroidery near the waistline on the left front of the undershirt.  It does say cold wash and tumble dry on low, so these may not be ideal if you tend to get them dirty, but for non-grubby uses they're a good all-around undershirt.  The V-neck is comfy and the whole shirt is nice and soft.  They have some give, but hold their shape well (Ive had others from another brand that tended to stretch out too much).  You cant go wrong with these!

Bought to keep me cool and pasty white when outdoors. Allows a breeze to help keep you cool and white color keeps it from absorbing sun heat. Also no greasy feeling arms because I can do without sunscreen.

Dries quickly if you go swimming or get sweaty but also useful for a quick dip to use as a evaporative cooling shirt. Arms are nice and long so they don't ride up my forearms.

Loose fitting and easy to reach and twist without looking like Im swimming in it. Easy to get on and off. Has stood up to harness strapping, hiking through vegetation, and other abrasions without wearing down or ripping at the seams when I pull it off.

My only wish is maybe a higher/tighter neck would help keep the face shield tucked down so I don't expose the back of my neck when it (shield) rides up a little over time. But I haven't gotten a burn and my neck isn't any redder for wearing this than it was before.

Amazing shirt! I got this to use as a very snug undershirt for gynecomastia, wearing it under my summer shirts to make me look much slimmer. It fits perfectly (VERY snug, as it should, & very comfortable), and looks fantastic, doing exactly what I bought it to do.

There is nothing better than a simple white undershirt, these are it.  Often stores say they carry these but you drive down to pick them up and poof they are not on the shelf.  Save the gas and the fuss, and buy from Amazon and you get what you wanted.

Great shirts that keep you cool throughout the day.  Shirts fit perfect and they are just the right length as well.

The shirt is marketed in a way that makes you think you'll get a solid white undershirt that 'keeps a flat collar' no matter the amount of washes..  Well, it's practically transparent, so you see your chest through it, (which I understand may appeal to some), and the amazing "X-Temp Comfort Cool" innovation is... because there is basically no shirt there..  Novel invention!

I got these to wear as an undershirt for my scrubs. They are perfect! Keep me cool and dry while I'm working and also act as a barrier to protect my skin. Definitely recommended.

For some reason, Under Armour stopped making this shirt in a men's v-neck form. They still make charged cotton crew necks, but no more men's v-necks (they do for women, but the v practically goes to the navel...).

The charged cotton material is so very nice! It's soft but light and perfect for any sort of exercise. The fact that it's cotton and not polyester means it breathes with your skin and doesn't scratch like so many of the synthetic materials. It's so much better than the material most of the other UA shirts are made of, and the v-neck cut makes the shirt feel even lighter, and airy enough to feel cool when you are running.

But of course, like most good things, it seems to have been discontinued. :(

Nice undershirt on cold days! Moisture wick. Same exact brand & style I was issued in the Army for cold weather gear. Bought a pair of each, tops & bottoms.

Finally found the perfect undershirt!  Some tshirts are too light and flimsy, while others are too thick and heavy. These are right in the middle and are perfect for wearing under my polos or button up shirts. Also, I prefer the grey over the white because it doesn't get dingey over time like my white undershirts did. I'm a 6ft 235lb man and the Large fits just right, so I would say they fit pretty true to size as well.

I use these as undershirts for work. I work in a factory that is HOT in the summer, and these do a great job to help keep me cool. Highly recommended.

Cool, light, breathable fabric. Definitely cooler and wicks sweat better than cotton tees.

Very comfortable and light weight shirts. They fit perfectly look and feel great as well. I am amazed with how light the fell when wearing them this shirt will be great for summer days because of the way they breath keeping you cool and a bonus my wife thinks I look great in them. I got this item at a discounted price.

Sept. 2017 -  These Hanes V-Necks are super thin which is great if you're looking for cool, soft comfort.  The V-Neck is cut extra deep so you don't have to worry about the white cotton creeping up to your neck for the world to see through your open collar.  I wear a 42" jacket so I ordered Large T-shirts.  After the first wash & dryer the T-shirts didn't shrink that much.  I'll continue to order the large size.  If you're looking for a lightweight, cool, soft, layer between starched shirts and your bare chest I recommend this product.
