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

Attended a wedding in Spain

As some one who sweats alot i was dubious as to whether this undershirt would help me. I needed to attend a wedding in Spain this Aug so thought why not try something like this out. Words cannot describe the confidence and joy i felt stood in the blistering heat feeling sweat running down my back but not a single damp/wet patch on my shirt. Not only did it do excatly what it said it would do but it did it for 8 hours straight, my shirt was bone dry upon arriving home. Delivery was quick and the personal note is a classy touch. 10/10

First time buying undershirts

Excellent product and great value. Purchasing from Robert Owen was very easy and hassle free.

Brilliantly made

Was going to an outdoor wedding in 27 degree heats so of course as I'm a naturally sweaty person, this was a concern. Through all the sunshine, all the dancing, and all the stuffy ceremony - my shirt remained bone dry. The rest cant be said for my face and hair, however id much rather that than a ruined shirt. Whilst on the expensive side, it certainly does the job very well and doesn't make you feel any hotter - great job!
