If you’re like me, you’re probably curious about the growing interest in moisture wicking undershirts.
What are they? Why are they getting so much interest? Does wearing them really make a difference?
Also, are wicking undershirts worth buying?
Note: This article has been updated several times since it’s original posting date & republished to keep it current. Reading it will give you a great overview of what wicking undershirts/shirts are, what they may have to offer, and is a great starting point.
However, over the years I have written many other articles about wicking (non-absorbing) undershirts and/or performance shirts. To quickly find other moisture wicking articles, you visit this link here.

Should I Buy A Moisture Wicking Undershirt?
Quite frankly, I had the exact same question, so I started doing a little research.
First, let me start off by saying that I look at this particular market segment from a consumer’s point of view (like you), not a manufacturer’s.
Companies like Under Armour, Coolmax, Holofiber, CoolNew, Nike Dri-FIT, and many others are promoting technological breakthroughs in constructing fabrics that are supposed to make you cooler in hotter situations. However, the bottom line for me is simple:
Do I notice and feel a difference when I wear moisture wicking undershirts?
Firstly, I am not here to question whether or not moisture wicking technology performs different than standard fabrics, because it certainly does.
Also, I have personally tested some moisture wicking shirts from CoolClothingUSA, Vdri, and Campbellsville at the gym and have found some of them to keep me very comfortable and cool.
But, are they practical or even recommended to wear as undershirts?
Food for thought:
Moisture-wicking clothing products are intended to keep you cooler by transferring moisture away from your body to the outer layer of the fabric.
If you’re wearing a moisture wicking undershirt, then wouldn’t your outer shirt get wetter (especially in the underarm area) than if you were wearing an undershirt that absorbed sweat?
I elaborated on this question in this post Moisture Wicking vs. Cotton Undershirts as well as in this article Do Moisture Wicking Undershirts Accelerate Sweat-Through.
What Does Moisture Wicking Mean?
I think it will be helpful if we first define the term “moisture wicking” (also reference Wikipedia). In simple terms, it’s the transference of moisture, vs. the absorption of moisture.
Transference vs. Absorption
What’s the difference you ask?
To begin with, transference occurs when non-absorbent clothing (like polyester and other synthetic blends) moves moisture from the skin’s surface to the outer layer of the fabric where it has more surface area and can typically dry faster than standard fabrics like cotton.
However, there are some cotton undershirts on the market that have moisture wicking characteristics or have been treated with synthetic substances (eg. Silnylon, Smartwool source: Wikipedia) that provide a similar effect.
Moreover, if you dig through Wikipedia a bit, you’ll see that these types of technical fabrics were developed primarily for high-performance activity sport wear and sporting goods.
And if you think about it, that makes perfect sense.
If you’re on a 100-mile bike ride, playing basketball, base jumping, or participating in the Baja 1000, where you are absolutely, positively going to sweat profusely, why wouldn’t you want to stay drier?
No question, you would want to.
There is no doubt in my mind that I would go drop the $40-$200 for that type of high-performance gear if I were doing those kinds of activities.
Is Wearing Sweat Wicking Undershirts Practical?
The question is whether or not I would invest in undershirts that are made of moisture wicking material, considering they are typically more expensive than standard undershirts.
If I were someone who sweats more than others or one who was affected by Hyperhidrosis (excessive sweating), then I would surely consider trying out these types of undershirts to see if they helped.
Additionally, If I worked outdoors in hotter situations and it was important for me to stay cool and dry, then I’d certainly give them a shot.
The fact is that I’m not and I don’t really sweat a lot when I’m wearing an undershirt doing my normal daily activities.
Primarily, I wear undershirts to protect my outer clothing from armpit stains and sweat marks, or to add in a protective layer when I’m wearing less comfortable (aka, itchy or starchy) shirts.
So I wouldn’t classify myself as one who would actively seek out higher-priced undershirts that are labeled as moisture wicking because it’s not solving a problem I have.
Mostly I look for undershirts that solve the fit, riding up, and bunching problems.
Nonetheless, I’m sure some of you visiting either do suffer from excess sweating or possibly work in a field where you sweat a lot during the day and you’re looking for some undershirts that may provide better moisture protection than your average everyday undershirt.

They Need To Fit Tight
Got an email from a reader who brought up an interesting point about moisture wicking undershirts.
Although he refers to compression-type undershirts, it likely applies equally to any type of moisture wicking undershirt and is something you should keep in mind.
One important point I don’t see you mention is that the Under Armour or other brand compression type shirts only work at wicking away moisture from the skin if the shirt is the proper size, meaning the shirt has to be in contact with the skin.
This means a skin tight fit.
And while I understand that most guys are afraid of seeing themselves in anything tight fitting, that is how they are designed.
Some guys wear the loose version over the compression version for that very reason.– Dave
