Sweatshield Undershirts Adds Sweat Proof Barrier and Increased Coverage Area
Looks like my buddy Tim over at Sweatshield Undershirts has been hard at work improving upon his line of sweat-through resistant undershirts.
From a reader…
I ordered sweatshield undershirts probably a year ago. Back then they under-arms consisted of 2 layers. This week I received a new order and instantly noticed several design changes.
The underarms now cover a much larger area, but also there is now some kind of shield woven into the middle of the 2 layers. I’m curious if you’re aware of this design change. I didn’t see anything about it on your site.
I reached out to Tim to see if he could provide any additional details.
Response from Tim @ Sweatshield Undershirts
Yes the new design of undershirts do have an extra layer in the underarm now and it took a long time to find the right fabric and design.
The main challenge was to get the right level of protection but keep the sweat shield light weight, thin, comfortable and discreet. Finally we made a fabric that is absorbent towelling like material on one side and flexible/pliable/soft waterproof but breathable layer on the other side. Then we had to work out how best to stitch that into the underarm and keep it separate from the outer layer for even better protection. All the stitching then had to overlap/interlock to ensure there is no leakage. On top of all that we increased the area of coverage to ensure there was no leakage on the sides.
So in short yes the style and design in the underarm has changed considerably.
Product Feedback from a Reader
I’d just like to follow and say that they worked perfectly, nothing came through and I sweat a lot. Tim is right, whatever the pad is, it is much different than the other guys. It still feels and moves like fabric. Much better than Advari or one of the other brands (can’t remember the name).
They stitch all around the pad and through the pad so it doesn’t wad or bunch up like the other shirts that have sewn in pads.
The only drawback I can think of for these shirts is if you are wearing a light fabric or the right type of dress shirt, you can see the seams through it due to the thickness.

Hi Tug
Thanks very much for noticing the changes to Sweatshield Undershirts and as always thanks so much for your awesome site.
The changes have been received extremely well and I am absolutely thrilled with the new undershirts. I suffer badly from Hyperhidrosis and that is actually me in those “before and after” pictures on the website.
Putting in extra protection in the underarm was something we tried from the very beginning but we just couldn’t find exactly the right combination of materials ( needs to be thin and discreet but also absorbent and impenetrable) but now I am happy to report that we have got it exactly right with the underarm protection. It came after a LOT of trial and error and testing but luckily I myself am the perfect test candidate and I knew if it worked for me then it would work for anyone.
You are right, the coverage area of the underarm sweat shields has also increased to provide better protection and avoid “leakage” around the edges.
The new undershirts are more expensive to make and ship (we include shipping in our cost) so we have had to increase the price but hopefully people will understand the reasons and appreciate the value.
Thanks again Tug and I am happy to answer any questions about the undershirts.
