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!

Speedy delivery, superb product, personal touch.

Order delivered next day despite free delivery. Lovely personalised note as part of the package. Have worn the undershirt twice (including recently in 28 degree heat under a suit) and it performed perfectly.

Sizes are not consistent

I’ve had lots of vests from here before, but not this particular style- it is the same size as the others I buy but it’s tight under the arms and gives me pins and needles in my hands so they are totally unwearable which is a shame given their cost. I’ve been really unlucky with the recent batch of vests I’ve purchased this time.

Leading undershirt so far

I’ve tried several undershirts and this is by far the best. Soft finish really makes it comfortable and the customer service for the order/delivery was very good.

Works for a few hours...

Good points are it doesn't seem visible under work shirts and pretty soon after putting on I don't notice I'm wearing it. Keeps sweat patches away for a few hours but I've found by mid afternoon they still show on light coloured shirts unfortunately
