Moisture-wicking but fabric doesn't breathe

The shirt looks nice, is comfortable and seems to be holding up in the wash. However, the fabric doesn't breathe. Therefore, underarm odor is a real issue for me after a day of wearing this shirt while sailing.

The fabric is the nice sweat wicking ability type.  However, the fit is too tight in the torso and prevents proper breathing.

I return to this cover up. The material does not breathe well.

Fits comfortably but does not breath. Keeps you warm in cold weather running but sweaty during cool down. Zipper sticks/jams when first put on.

For a 100 percent cotton shirt breathing is dismal. Probably the dye is plugging up the pores. I had that problem with another shirt. I soaked it in bleach to get rid of the dye. Now I have a very comfortable ty dye shirt. I just wish I liked ty dye

Nice shirt.  Advertised as athletic moisture wicking.  It is implied these are like another brand that provides "armor" against moisture.  They are not as the are just a poly cotton blend.  Still nice shirts for work and such.

Moisture wicking does its job a and the ventilation is good. But the crew socks around the shins and back calfs are really tight even after a wash.

First of all, performance fabrics are moisture wicking.  This is not.

Jackets have a stiffness, or thickness to them.  THIS IS THIN.  The style is nice, but the fabric is not.

This is a shirt.  Not a Jacket.

I paid $32 and am considering sending it back.

Calvin Klein is cheating us by labeling his line performance.  AGAIN  Performance clothing uses technology to regulate body temperture.  Moisture wicking fabric is a must

Great product, although I wish the fabric was made of a more breathable material. I hesitate to use it for long periods of time in hot weather.

I bought for use while hiking in southern Calif desert. The product does feel quite cool when wet and draped around my neck. But when it dries out it becomes hard and stiff like cardboard. Not nice. It's a very strange type of "fabric" and has a slight chemical smell. It's also kind of bulky. I cut mine lengthways so now i have two towels but probably won't use either one much. A simple microfiber towel would be more useful i think.

A decent pair of rain pants for the price, but definitely NOT breathable.  I've worn them four times: twice when the roads were just wet, twice when it's been raining.  When the roads were just wet the pants were wetter on the inside than the outside due to condensation of sweat.  It was also cold outside which, no doubt added to the condensation build up.  But when it was raining they were definitely keeping the rain out.  So it's a mix.

I got this to wear on my wedding day while getting ready (and purchased more colorful robes as gifts for the bridesmaids). It looks very classy and regal, but be warned -- it gets very hot. The fabric is not at all breathable, which makes it difficult to wear this for long periods of time or in places that aren't well ventilated.

I loved these when I used them in Atlanta, specially during winter.
Now Ive moved to a very hot and humid place and its not breathable at all. And I discovered this the worst way, so if you live in a hot and humid climate, use cotton underwear. These are mainly polyester.

This fabric is not absorbent like the terry cloth robe my husband used to wear and he sweats in it and is uncomfortable sometimes.  On the plus side, he says it's very warm and cozy on very cold mornings.

After wearing this jacket in a few light rains, I thought I had the perfect raincoat. Today, however, I changed my mind. Wearing the jacket in a moderate storm, I found myself dry for about 20 minutes. Then, I got cold and noticed that the fabric was absorbing moisture rather than repelling it. How disappointing to see the retun policy is over. Truly this was the first real rain I wore the jacket in and it truly failed!

Purchase some type of water repellant to treat the inner layer of cotton. The cotton molds and retains moisture. The sellers were responsive and immediately sent me a new cover. The construction is superb but the choice of a raw untreated cotton lining is a mistake. I had mold in less than 1 month in the rainy season.

I have to take this out of the drier right when the cycle finishes, otherwise it wrinkles.  The other wicking athletic shirts I have bought for my husband (including Champion Men's Double Dry Training Tee, which I bought at the same time) do not wrinkle nearly as much.
