Why should we listen to old wives’ tales? An apple a day, counting sheep, red sky at night… Whether these tales are brilliance or bonkers, if your gran ever harped on at you about tucking in your vest, she was onto something…
Wearing a vest is the best way to keep your fingers and toes toasty this winter. What, that sleeveless, sockless garment? Absolutely. Vests are simply the best insulating layer.

The Lies About Hats
The Truth About Vests
Why, then, are vests simply the best if the body loses heat at the same rate all over? How are they any different from putting on a hat?
It’s all about thermoregulation. Our bodies have two different temperatures; a core temperature and a skin temperature. Our core temperature is the temperature of our vital organs, brain and blood. It is crucial that this remains constant at around 36.9’C for the proper working of our bodies’ enzymes: if this fluctuates we are at risk of becoming dangerously ill, or even dying. On the other hand, our skin temperature varies more, as it is influenced by the external environment and our activity.
We “feel cold” when environmental factors (cold air, wind or water) cause our skin temperature to drop. One of our bodies’ thermoregulatory responses includes vasoconstriction, whereby the blood vessels close to the surface of our skin constrict, reducing the blood flow to the tissues under the skin. This allows less heat to escape from the blood, and redirects the body’s heat away from its extremities and towards its core, thereby preserving the vital organs for as long as possible.
This is why when we feel chilly our skin turns a little blue, and our fingers, ears, nose and toes loose feeling first: they are the furthest from our vital organs and therefore lowest in the pecking order. That’s right: not only are you freezing your nadgers off, but your body has already started sacrificing limbs.
Here’s why a vest is best: by providing an extra layer of insulation around your core, you help prevent your torso losing heat and your core temperature dropping. Your body will be able to keep warm blood flowing to your extremities for longer, and your skin temperature will remain more stable.
Not All Vests Were Created Equal
Unfortunately, there’s a little more to it than that – just any old vest won’t do. In the outdoors world, where staying warm really is a matter of life and death, there is an old saying: cotton kills. And while we’re not suggesting your drawers harbour homicidal tees, this saying really does have the final… say.
Cotton will soak up any water vapour naturally produced by your body (sweat, for example) and will stay soggy all day long. Water is an excellent conductor of heat: wearing a wet vest will lower your skin temperature and sap your body’s warmth, leaving you cold, wet and clammy. Plus, wet cotton chafes, and no one likes chafing. If you are going extreme in your outdoor activities you’ll need a synthetic base layer to wick the moisture away so you stay warm and dry.
In the office, where staying comfortable is the top priority you’ll want a natural fabric next to your skin. In this situation you could wear cotton, or could wear something even better. Introducing the Robert Owen undershirt.
Simply the Best… Better Than All the Vests
Our Micro-modal and Bamboo Viscose vests are the best base layers for the office. Their soft and light-weight fabrics are perfectly balanced between absorption and breathability. Whilst the Micro-modal and Viscose fibres absorb water vapour (e.g. sweat) and stop it travelling through, or evaporating onto, your outer layer, the fabrics remain breathable: moisture is continually drawn away from your skin so that you stay feeling fresh and warm throughout the day. Moreover, unlike polyester fabrics, Micro-modal and Bamboo Viscose are cellulose-based and do not encourage the growth of smelly bacteria. A Robert Owen Undershirt will help prevent sweat patches on your outer layer and any lingering pong – all whilst helping you stay warm and dry. Neat right? We think so.
One more thing: at Robert Owen, we have taken the utmost care to specially design our undershirt so that it stays under your shirt. Our vests are silky smooth and won’t rumple even under tight tee; they are cut long so that, once tucked in, they stay put; and with a deep v-neck or crew cut, they stay hidden under your shirt whether you roll open-collared or button-up tight.
Seems too good to be true? We promise our undershirt isn’t a myth: we offer a satisfaction guarantee, because if you don’t look good, we don’t look good. Phew, that ought to keep your gran happy. At Robert Owen Undershirts, there’s something for every occasion.
