Size chart shows sizes in inches. XS is 36, S is 38, M is 40, L is 42, XL is 44

Not sure about your size?

Our sizing is based on a UK grading system so please check your chest size. Measure your chest with arms straight at sides, around the fullest part, close under the arms.

Men's undershirts are designed to fit but not be tight. The 5% Spandex gives the fabric a 20% stretch so our undershirts fit most shapes. If you prefer a looser fit choose one size up to allow the undershirt to hang rather than fit.

If you are unsure about your size we are here to help you. Send an email to and we'll find the ideal size for you.

Stop worrying about sweat showing on your shirt (sweat through). I know this can be something which causes you to feel self-conscious. It did me, which is why I designed this product. The men's enhanced sweat protect undershirt provides a layer between you and your shirt significantly reducing sweat through. It’s made from bamboo viscose which is a sweat absorbing fabric. The most important feature of the enhanced sweat protect undershirt is the double underarm panels under the armpit. Why have a double layer underarms? To absorb more sweat; more sweat than a single layer of fabric. What’s more is there is a unique pocket space formed in the double panel under the arm just large enough to hold a sweat pad or dress shield. The sweat pad is held in place under the arm where it is providing extra sweat protection making this a nearly sweatproof shirt. Once used the sweat shield is disposed of. No other men's undershirt has this feature.

Wearing an extra layer will help keep you cooler (in summer). It seems a bit counter-intuitive to add a layer to keep you cooler but it works. The bamboo viscose fabric was chosen as its lightweight meaning you often forget you have it on. It absorbs sweat to then evaporate with air which helps to cool the body. The bamboo viscose also feels amazing; it makes the softest undershirt. It never gets too hot (like synthetics). It never feels scratchy (like synthetics can). It's lighter to wear than cotton, and softer on the skin (unless you compare with really expensive cotton).

You won’t be showing your undershirt to the world. This enhanced Sweat Protect undershirt has been designed with a deep v neck so it won't show under your dress shirt even with buttons open.

No more of those uncomfortable tucking in adjustments. We have made it longer than a normal t-shirt so that it’s long enough to stay tucked in, no matter what. We’ve had feedback that they have been tested rigorously while at children’s parties and they have survived the challenge!

You may even forget that you have it on! All our men's undershirts have a body contouring fit which means they feel fitted. The 5% Spandex (or elastane to give it a common UK name) gives it four-way stretch so it moves with you and in doing so keeps in contact with your body. This helps you to forget you have it on and also means there are no extra ‘folds’ when being tucked into your trousers.

You will feel more comfortable. Many of our customers try one of our range and then come back and order enough to last a week. When I first designed this undershirt I started to wear them every day for work. I now wear them all the time. I change into one of my crew necks in the evening to wear with my pyjamas; picking a coloured undershirt to match. How did I survive without them?
