Life-changing product
Bought for a full day assessment centre job interview. As recommended I purchased 1 size down from my usual tshirt size and this was the correct choice. This undershirt should be skin tight yet still comfortable which it was. I'm somebody who has always suffered from hypohydrosis. I ALWAYS take a jacket or coat with me which I use to cover up sweat, and hide my embarrassment, but this ultimately makes the problem worse. For this job interview though, I had to wear a smart office shirt without a jacket (company dress code). Within 30 minutes I would usually have underarm sweat marks and back sweat showing through the shirt as large wet patches. With this undershirt on, absolutely NOTHING!! Dry throughout the entire day! As there is no padding on the back (just underarms), I worried that my back would still be vulnerable, however the 95% bamboo material did an excellent job of absorption, not allowing any moisture to break through to my outer officewear. To emphasise, this was in the U.K. on the hottest day in over 40 years (35°c), in an office block without air conditioning, doing team-building tasks that required physical hard work. After the team-building task, all candidates were sweating profusely from the face, including me, however I was one of the few without a mark on my shirt. This allowed me to stay calm and focus on the interview, without worrying about embarrising marks I would usually have had on my shirt. I did well at the interview and this product completely improved my confidence on the day. As someone that has uncontrollable sweat on even cold days, the fact this undershirt did its job in much hotter conditions and in a stressful situation, is nothing short of a miracle! After a short while of wearing the shirt, I didn't really notice I had it on; this is also why it's important that the undershirt is not a lose fit, it should be skin tight but not uncomfortable. The shirt is unnoticebale to others looking at you, there's nothing to suggest you are wearing anything other than an office shirt by itself. If the idea of wearing formal shirts and certain colours fills you with dread, give this a try. It's expensive yes, but if you suffer from hypohydrosis, it's a small price to pay to get your confidence back. I paid for this product myself and have written this review as an unbiased reaction to my experience with the undershirt.

Absolute game changer.
This really works. I couldn't believe it. If you sweat a lot or work in a job where one has to dress formally, and sometimes, uncomfortably, this can really help keep those sweat patches away and keep you confident! Worth every penny for me.

Great product - would highly recommend
I bought this product for my husband who suffers with embarrassing wet rings when wearing coloured shirts. He always wears an undershirt but these were not doing the job. I saw this product online and ordered a couple for him to try. He tried it on a particularly hot day and was very very impressed. Nothing at all showed through to his outer shirt. The only point he made was that his armpits felt very wet but once he got used to it, it was fine. Fantastic product to finally get rid of those horrible looking wet patches. The size and fitting was also great.

almost like gym gear
I saw a review of these on Youtube and I went on to purchase 5 of these. I mainly wear extra slim fit Charles Tyrwhitt shirts, or fitted TM Lewin. They are slightly fairly on the white shirts, which is a bit of a drawback, but mainly I wear blue, blue/white and they are barely visible. I am 5 ft 9, lean and the medium fits well. It is a bit strange at first, but you get used to them. It is really nothing major and if you are not a heavy sweater, then the sweat that does form is barely noticeable (for yourself to to feel, not others to see). The material is very stretchy, almost like gym gear. They work perfectly to stop armpit sweat marks, however the main downside is that they are very close and it makes you quite hot, especially on the underground. That said, I have been wearing these every day for last 3 months while commuting to London (40 mins on tube) and sweat has not broken anywhere, nor have I got to the point of wishing I was not wearing it at the time. They do need to be more breathable, which is why for summer they will probably not be suitable for heavier sweaters, but I look forward to wearing them in the colder seasons. I have seen some reviews saying that they discolour, but I have not found this with mine. Perhaps this is because I cycle through the 5 I have though. I would recommend buying these tshirts if you are a medium sweater, have nice shirts and don't spend too long in a close/hot environment. If you haven't heard of it, a product I would also recommend is TripleDry. It is a roll on deodorant that you use at night time. Check it out.

It’s ok
Does the job but can be seen around the neck line. This means you can wear with a T-shirt as it would look stupid. Good for jumpers etc.

First class undershirt
Excellent undershirt which is very comfortable and fits superbly . Used it when I went on holiday and not once did any sweat come through on my shirt even although it was very hot and had been up dancing most nights and I still felt fresh at end of night . Would definitely recommend these to anybody as I have already ordered more .

Sweat Box,
Yes this absorbs sweat under arms, but it needs to, it is like wearing a heated vest in high summer. May as well stick to plain cotton T-shirt at fraction of cost. Never buy (or wear) again!

For anyone who worries about sweat marks under arm pits, buy this shirt. Will be buying more. Bit expensive but worth every penny

The underarm does not fully protect from sweets because it was not designed to fully hold tight your underarm when wearing.

Ho scelto di prendere una taglia in meno come descritto da altri utenti, ma appunto, scegliendo la “S”, l’ho trovata molto molto aderente, forse troppo. Maglietta perfetta nel suo insieme. Testata durante l’arco di una serata (5/6) ore e non c’è stata neanche una goccia di sudore che è riuscita a superare lo strato ascellare della maglietta. Sono soddisfatto al 100% (soffro di iperidrosi e prima ero capace anche di bagnare 2/3 capi insieme) Saluti!!!

La mejor camiseta anti sudor que he tenido. Ya la tengo más de dos años, y nunca he marcado la camisa. Totalmente recomendable.
