Undershirts by material
Cotton undershirts are the classic: breathable, absorbent, and particularly skin-friendly – perfect for sensitive skin and daily use. Merino wool offers natural temperature regulation and is odor-inhibiting, ideal for travel and long days. Microfiber and modal undershirts impress with their lightweight and extremely fast moisture transport – the first choice for sports and warm days. Luxury undershirts with a silk content or made of fine Egyptian cotton offer an incomparably soft feel on the skin.
Undershirts by fit
Crew-neck undershirts are the versatile all-rounder under shirts and sweaters. V-neck undershirts remain discreetly invisible with an open shirt collar. Muscle shirts and tank tops offer maximum freedom of movement and are ideal under close-fitting clothing or as a light base layer in summer. Seamless undershirts prevent irritating pressure points and do not show under figure-hugging outerwear – appreciated by wearers with sensitive skin as well as by athletes.
This category is ideal for women and men in Switzerland who value high-quality basics – whether for everyday business under a shirt, as a warming layer in winter, as a breathable base layer during sports, or simply for a pleasantly soft feel on the skin. High-quality undershirts also make a thoughtful gift for partners, family members, or friends.
Quality, materials & workmanship
When buying undershirts, it is worth paying attention to high-quality materials such as long-staple cotton, merino wool, or modal, clean finishing of the seams, and a fit that gently hugs the body without constricting. Brands from Switzerland such as CALIDA, ZIMMERLI, and HANRO have stood for excellent quality and durability for decades.
Frequently asked questions
What is the difference between an undershirt and a T-shirt?▾
An undershirt is usually cut tighter, lies closer to the body, and serves as an invisible base layer under outerwear. A T-shirt is cut looser and is mostly worn as a standalone garment. Undershirts also are often made of finer, breathable materials for optimal wearing comfort on the skin.
Which materials are best for undershirts?▾
Cotton is especially skin-friendly, breathable, and absorbent – ideal for sensitive skin. Merino wool is excellent for temperature regulation and odor neutrality. Microfiber and modal impress with lightness and fast moisture transport. For luxury demands, undershirts made of fine Egyptian cotton or with a silk content are an excellent choice.
What types of undershirts are there and what are they suitable for?▾
Classic crew-neck undershirts are suitable under closed shirts and sweaters. V-neck undershirts remain invisible with an open shirt collar. Muscle shirts without sleeves offer maximum freedom of movement and are ideal under close-fitting clothing. Tank tops serve as a light base layer on warm days.
When should you wear an undershirt?▾
An undershirt is always useful when you want a layer between your skin and outerwear – for example to absorb sweat, protect outerwear, or provide additional warmth. Especially under business shirts, in cool temperatures, or with sensitive skin, an undershirt offers noticeable added value.
How do I properly care for undershirts so they last a long time?▾
Undershirts should be washed according to the manufacturer's instructions – usually at 30 or 40 degrees on a gentle cycle. Fabric softener should be avoided if possible, as it can impair breathability. For drying, it is best to let the undershirt dry lying flat and not treat it in a tumble dryer to maintain shape and elasticity.
What size should I choose for undershirts – fitted or loose?▾
Undershirts should sit close to the body without constricting. A close fit ensures that the undershirt does not show under outerwear and offers optimal moisture transport. If you prefer it airier, you can choose one size larger – but then care should be taken that no wrinkles appear.
Are there seamless undershirts and who are they suitable for?▾
Yes, seamless undershirts are knitted in one piece and have no annoying side seams. They are ideal for anyone with sensitive skin or whose seams would show under figure-hugging clothing. Many athletes also appreciate seamless undershirts because of the reduced friction potential.
Are undershirts made of cotton or microfiber better?▾
It depends on the intended use. Cotton undershirts are breathable, absorbent, and especially skin-friendly – perfect for everyday wear and sensitive skin. Microfiber undershirts score with extremely fast moisture transport and drying, making them ideal for sporting activities or warm days. Many premium manufacturers combine both materials for an optimal wearing feel.
