Classic Crew Neck Slim Fit Undershirt (The Chester)

£29.00 GBP

Ivory White
Sky Blue
Midnight Blue



This is the classic crew neck undershirt for wearing under a shirt and tie, ideal for the suited and booted look.

It is a slim cut for a fitted and comfortable feel. This is a versatile, easy-wearing undershirt made from breathable and natural feeling Bamboo Viscose, which is one of the softest materials you can buy.

The Chester is an undershirt you can wear under tee shirts and short sleeved summer shirts. We've cut the sleeves of the Chester design that bit shorter, so it won't show under your summer wardrobe. In hot weather, it's ideal to wear under a baggier crew neck tee shirt. You get the benefits of a cooling vest as the undershirt traps sweat and then cools your body as it evaporates without showing on your tee shirt. Or you can wear it for an extra layer in cold weather to keep the chill air away from your body. Cooling or insulating this purpose designed undershirt can do both.

Why do we talk about our undershirts being purpose designed? You might think that since your undershirt is hidden under another shirt that fit doesn’t matter what you wear. This couldn’t be further from the truth. A cotton t-shirt is designed to be worn on the outside. The cut is too baggy, the cotton too stiff and the body is not long enough. The result? A wrinkled and uncomfortable mess that looks bulky in all the wrong places.

To avoid all the problems of underwear riding up we've made the Chester men's undershirt extra long in the body. We added extra length, so it'll stay tucked in, but because it is extra long, it also makes it an ideal undershirt for tall men.

The Chester crew neck undershirt is available in four colours. White is good for general purpose, but we also make it in tan, light blue (sky blue) and navy blue (midnight blue).

We always make undershirt to fit and feel amazing on your skin. The Chester is the right choice if you want a lightweight men's undershirt that's extra long and extra comfortable for everyday use. It's perfect as a cooling vest in summer or as an extra natural feeling layer in winter. You won't find a more comfortable undershirt in the UK.

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.

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.
