This is an excellent, High Quality shirt. It is a Van Heusen and it lives up to the product reputation. The shirt appears to be well made and durable. The cloth feels sturdy and yet it breathes. I live in Florida and have found the shirt to be cooler than some other shirts. They look really good coming out of the dryer as long as you take them out as soon as they dry and do not leave them sitting. I have noticed that after hanging for a while they look even better than when first removed from the dryer. I have found ironing to be unnecessary as they look good without it.  However, if you want to look super sharp you can elect to starch and iron the shirts. I am an IT person and have to dress nicely but still need to crawl under desks and such from time to time and these shirts are a perfect combination work/dress shirt. I bought 6 of them in 3 different colors, wear them everyday and have been very pleased. I will continue to buy Van Heusen. Sometimes the brand name is worth it.

Great shirts. I have been looking for shirts to fit my needs for months now. I use them in a professional setting as part of my "work" uniform. Many of the shirts I have tried other shirts like these and they have been so thin that you can see chest hair beneath the shirts. I keep well trimmed and don't have a monkey chest full of hair. They are a nice weight shirt. They look professional are well made and very comfortable and cool here in the south Texas heat. Also the are perfect for embroidering a logo or employees names.  The white shirts I ordered I returned because you could see some texture from chest hair. These are the best I have found.

The fabric is excellent and lives up to its wrinkle-free claim as well as any other wrinkle-free garment.  None of the shirts I've purchased from this company are fitted, e.g. darts, which I'd prefer.

These shirts are a great buy. They fit well and the material is surprisingly thick as compared to other undershirts. They're slightly irritating until you wash them, but most clothing is like that.

These shirts are fantastic, and the price is right!

EDIT July 30th, 2010:

So, I've been wearing them for a while and they've still held up very well. I'm outside a lot where the heat index is usually around 100 degrees to 110 degrees Fahrenheit and there is no sweat staining of any kind. The "tagless" feature is proving to be much more comfortable than I originally thought.

I remain satisfied with my purchase!

I just ordered 5 of these shirts in different colors to wear under jackets for work. They are appropriate for both work and casual. They wash well (I line dry) and don't need ironing. Also, I travel a lot and they are light and travel well.

My husband loves  these shirts. They are comfortable, breathable, and don't wrinkle at all.

I love these shirts because they don't fade, they are easy to clean, and they are very high quality. I definitely recommend them.

I prefer to wear simple shirts that do not have any advertising on them.  These next level 6010 tri-blend shirts fill that need perfectly.  They are sized right, last a long time, and are very comfortable.  Just make sure not to cook in them.  Any splash of oil on them will be permanent.

Excellent shirts, very comfortable, well designed, and made from a high quality natural cotton fiber. Received many compliments from friends as well. I have now bought five for the summer, the price being a very attractive proposition.

My closet is full of ordinary polo shirts.  Most of them are 100% cotton and need ironing each time I wear them.  Even though I initially wash them in cold water on delicate cycle, they will shrink some.  They continue to slightly fade with each washing.  I always hang my polos up to dry.  I have a few made of 100% polyester.  This is the modern polyester, not the old-fashioned type that itched me and gave me a heat rash if I sweated profusely in the sun.

  I couldn't wait to wear the Mens Performance Gold Grid Polo from IZOD.  It is made of 100% polyester.  Black has always looked good on me; it makes me look thinner.  I pulled this shirt out of the bag in which it was shipped and put it on.  It didn't needed washing or ironing.  It didn't have any wrinkles.  I wore it to church with some blue jeans.  (My church is very casual and laid back.)  After church, I cooked a pasta lunch and then my girlfriend, Tammy, and I went walking through my neighborhood.

  The temperatures were in the nineties.  However, I like hot weather.  It didn't bother me.  Most importantly, my shirt didn't stick or cling tenaciously to me.  I didn't get a heat rash.  (Its moisture wicking material kept the sweat off of me.)  The shirt is a size large and it fit me perfectly.  I am short and slightly chubby and normally wear a size large.  This IZOD polo shirt allowed me plenty of movement in my arms.  It floated around my big belly the best it could.  (I wasn't expecting miracles.)  The shirt hangs long and looks great with blue jeans and brown khakis.

  When it comes to shirts that are 100% polyester, I try to be as gentle as possible when cleaning them.  I was very gentle with the IZOD golf polo shirt.  First, I turned the shirt inside out.  (It seems that all the new shirts I buy lately have care instructions that ask the owner to turn the garment inside out.)  I washed it on hand wash cycle in cold water.  Afterwards, I threw it over the back of a chair.  It practically dried overnight and didn't have any wrinkles.  (Neither did it have any picks, snags, holes or tears.)  I do not want to take an iron to a garment that is 100% polyester, especially one that is this expensive.

  Initially, I was skeptical about these 100% polyester shirts.  However, I am slowly cozying up to them.  We live in a high tech society.  It only makes sense that the technology would extend from our electronics to our clothing.  This IZOD gold shirt has moisture wicking material that protects us from sweat and material that protects us from harmful UV rays.  This is an awesome shirt for wearing outdoors for long periods of time.  I don't golf but I do like walking and hiking in the sun.  Friends of mine have gone golfing and come back burnt to a crisp.  I can see why this would make a great golf shirt.  I may buy one for my good friend Ted who likes to golf a lot on weekends.

Excellent fit, nice fabrics an colors. These shirts are wrinkle free right out of the package. have not run through wash yet so I don't know of shrinkage or color fastness, but seems like a great value. Plan to order more.

I love these shirts and have them in several colors.  You can wear them with anything casual.  They breathe well, wash well, and don't wrinkle, and are good for travelling.

I really like these shirts a lot. I'm 6'0 feet tall and around 185lbs ..

The problem I have as a taller,thinner guy is that shirts can fit VERY badly. I've tried other brands of t-shirts like Hanes and Fruit of the loom, the problem I always have is the sleeves are usually always so big, or the shirt is just too wide, and too short...or a combination of all those problems.

These Next Level shirts though... I really like them. Sleeves aren't baggy,and the overall length and width of the shirts are very good... I've bought about 10 of these, maybe more, I lost count. The quality of the shirts are very consistent..They arrive slightly bigger and only shrink a small amount (as far as I can tell).. After a wash they still look and feel excellent.

Highly recommended from a thinner/taller guy. and they aren't too expensive either,
