Men's Back Sweat Proof Undershirt for Back Sweating (Crew Neck)

Best product I’ve ever purchased to prevent excessive back sweating, which has been a vexing problem for years. I’m a true believer... I’ll be a customer for life

I am so happy with this shirt that I just placed an order for another shirt.
Whereas my shirt is usually wet with sweat by the time I reach work on mornings from day one after I started wearing the Sweatshield undershirt for back sweating my clothes are dry. It is like a miracle. Wish I had such a shirt years ago.

I suffer from wet armpits, particularly at work, no matter the temperature so I have had to live with sweat marks under my arms. These undershirts definitely stop any sweat coming through. I no longer have to worry about sweat patches and raising my arms. If you want something that will stop embarrassing sweat marks coming through your shirts these will do the job no question.
However there are some things to bear in mind with this product. Not necessarily negatives but side effects.
1. The padding is quite bulky so if you wear slim fitting tops it's not a comfortable fit. The undershirt is close fitting but it does add bulk. Anything worn over the top of it needs to be loose enough to accomodate this. For me it only works under sweaters and shirts that are not too slim fitting anything else doesn't fit properly.
2. The padding under the arms stops sweat from getting through, but it does not soak it up to the extent that your armpits dry out. You do feel like you have 2 slightly damp nappies under your arms. It's not uncomfortable but it does take getting used to. It's a price worth paying though.
3. as above, the padding takes a long time to dry out. Once it is wet it stays wet. When you wash them they can take several days to fully dry out.
4. if your white shirt is light weight and fairly see through then you can see the undershirt underneath and make out the padded areas. however I can now buy colored shirts! :)

I am an extreme under arm sweater since teenage years and this product really has made a difference, normally after 10 minutes of wearing a regular t-shirt or work shirt I will have big visable patches but I wore this undershirt for 10 hours in hot weather and had barely even made a stain, if anything I would prefer the sweat protection bit to go abit more round the chest but other than that 100% buy you will not regret.

Very good quality, super comfy and fast delivery
