I cannot recommend this product highly enough. It's absolutely fantastic, and great value as well. In a small-but-meaningful way, this is life-changing!
Finally I can go through the day and not have to worry about raising my arms or saving sweat from the pits to try and prevent soak through.
Fantastic shirts. These are a life changer!
I've loved these undershirts since the first time I tried them. Great quality and they last a long time.
If you spend all day worrying that you’re sweating through your shirt, this is the product for you. I’ve been using them for years and nothing ever gets through, no matter how stressful the situation.
I’ve been buying these shirts for 5-6 years now and there is nothing better I’ve been able to find. The price seems high but they are very durable and will last far longer than a regular undershirt. But the key is that you will NEVER sweat through them. This means that your dress shirts (or t shirts or sweatshirts or whatever you wear normally) will never have pit stains. I mean that both in terms of being embarrassed during a meeting with a cloud or sweat on your garment but also in terms of long term maintenance of that garment. Pit stains are hard to get out and ultimately will ruin clothes. So with that, this is one of the smartest investments I continue to make and frankly if you sweat as much as I do, it’s one you can’t afford to skip.
The V-neck undershirts are working well, enjoying the comfort, good product.
My son found the undershirt worked fantastic. The outsideshirt kept him dried. Definetely works as stated. Very happy. Thank you.
Excellent fast shipping. Outstanding product that really works to keep you dry.
Men's Size Chart
Choose V Neck for use with polo shirts, t-shirts, casual shirts and business shirts when you want to wear them open collared (unbuttoned).
Choose Crew Neck for a sharp undershirt neckline with an open collared shirt. If wearing a buttoned up collar with a tie then crew neck will make the undershirt neckline less visible.
