Great undershirt

My first time buying from Robert Owen. The sweat blocking works very well.

Well what can I say… WOW WOW WOW!

Well what can I say… WOW WOW WOW! I have an extreme problem with underarm sweating. I could not find a solution anywhere. I tried underarm pads and they just kept slipping down my body because of the sweat! So I went back into google to try once again to find a solution for myself. That’s when I came across Robert Owen. I read some of the reviews and thought I would take a chance and place an order. They had a deal on so I ordered five undershirts. I was starting a new job the following Monday and knew the sweat issue world certainly raise its head! Also I was so fed up of buying really nice shirts and having them ruined with underarm sweat over time. Anyway the undershirts arrived very quickly. I live in the Highlands of Scotland so wasn’t expecting such a quick dispatch. When I opened the package there was a hand written note from Yvonne thanking me for my business which was a really nice touch. So fast forward to my first week in the new office, nerves we’re running wild and so was the sweat or so I thought….. I went for a coffee break around 10am by this time I had the undershirt on for 2 hours and knew for a fact I would have the dreaded underarm sweat patches on my brand new shirt - but NO! Not a sweat patch to be seen!! I couldn’t believe it, I was in complete disbelief. My confidence immediately shot up! I had finally conquered this awful sweat problem that’s plagued me for years! I didn’t want to write a review straight away so I am now a few weeks down the line and I can confirm these undershirts have not let me down once! Infact I have so much confidence in them now I don’t even go to the bathroom to check if there is any sign of wetness under my arms. Absolutely outstanding work by these guys. Please keep up the good work. P.S. I am writing this review on a plane journey to Italy and guess what I am a nervous flyer (who knew!) haha. Anyway I can report my underarms are 100% dry!!! All the best and thanks again to Yvonne & Robert.

Bought as a gift for my son who says that these undershirts have changed his life! He says they're very comfortable and he can now wear whatever he wants without fear of being a sweaty mess. Slight mix up with my order but resolved promptly without any issues. Will definately be buying more, a happy son makes a happy mum!

I find the sleeves to be too long. They are fine if you are wearing a long sleeve shirt, but if wearing a t-shirt/short sleeve shirt, the sleeves of the undershirt are visible.

Great fit and works

Great experience and great product. Kept me dry throughout whole wedding after dancing the night away.

Excellent - This works

Have tried other ways to avoid sweat patches, however, this vest really worked well. I wore this with a white shirt at a wedding. I had a 2 hour drive to the venue and had a suit jacket on all day and into the evening. When I took off the suit jacket, there was no sign of sweat on my shirt, I was very impressed! Will certainly purchase again.

Yes it works!

This shirt fits as expected, does in fact stop sweat getting through to my shirt (tested on a couple of business trips) and feels nice against the skin. I find the arms ride up a little bit, but this shouldn't be a problem if you don't have my magnificent biceps :D
