Harry’s Warm-Weather Fabric Guide
On the year’s hottest days, we repeatedly return to these fabrics – and you should too.
No matter the garment, clothing can only function as well as its fabric allows. A winter coat made out of cotton won’t stand up to snow and –20°C temperatures; similarly, your favourite cashmere sweater wouldn’t be your first choice come the heat of high summer.
Dressing well in summer is often a balancing act. Fortunately, choosing the right fabric makes all the difference.
When you truly appreciate how certain fabrics are designed to perform, you understand how to wear them and why they deserve a place in your wardrobe. And, during an extreme season like summer, it’s in your best interest to know which clothes will keep you the coolest.
Linen is perhaps the quintessential summer fabric. This loosely woven natural fabric is made from flax fibres and the earliest evidence of linen dates back to over 30,000 years ago.
Linen’s open weave provides its natural lightweight, breathable, and odour resistant properties, though it’s no delicate material – the powerhouse summer fabric is also renowned for its durability and quick-drying quality. Linen’s characteristic crisp texture often creates wrinkles and creases, which offers a casual, laid-back aesthetic that adds to the fabric’s easy-going appeal.
Linen is best worn slightly loose to the body to allow for cooling airflow between the garment and your skin. For this reason, the best linen garments include shirts, trousers , knitwear, tailoring , and outerwear.
Linen’s natural proclivity to wrinkle should be embraced, not feared. A few slight wrinkles are bound to appear around high-use areas — like elbows, armholes, or knees — and these only add to the fabric's inherent charm and laid-back appeal. After a few wears, however, any deeper wrinkles or folds should be pressed or steamed out.
Cotton is one of the most widely worn fabrics in the world — especially during the summer months. Cotton’s natural softness, breathability, and versatility make it a reliable warm-weather staple, alongside its crisp hand-feel, which feels cool against the skin on the year’s warmest days.
Made from the fibres of the cotton plant, cotton's natural hollow structure allows it to absorb moisture and release heat, keeping you comfortable as temperatures rise. It's a durable, easy-care fabric that softens with wear, and its ability to take dye well means it's available in an endless range of colours and patterns.
Not all cotton is created equal, however. In warm weather, look for finer, lighter weaves — poplin, voile, or oxford cloth — which allow for greater airflow than heavier constructions like twill or flannel. Cotton is best suited to casual and smart-casual garments including shirts, chinos, shorts, and lightweight jackets or blousons.
Due to its relatively matte finish and dry texture, pure cotton is best suited to more casual garments. Cotton compositions blended with silk, linen, virgin wool, or cashmere add an elevated lustre and texture, lending themselves to more formal garments like suiting and knitwear.
Just as the name implies, tropical wool is a variation of lightweight wool, most typically used for suiting, designed for tropical or warm climates.
Woven from fine, high-twist wool yarns in a loose, open construction, tropical wool is significantly lighter and more breathable than its cold-weather counterparts. The high-twist yarn creates natural tension in the weave, which allows air to circulate freely while giving the fabric a characteristic smooth, crisp hand-feel that resists wrinkling — a quality that makes it particularly well-suited to travel.
Tropical wool's combination of breathability, structure, and drape makes it the fabric of choice for warm-weather tailoring. If you need a suit or trousers that will carry you comfortably through a summer workday or a formal warm-weather occasion, tropical wool is the answer.
Tropical wool's high-twist yarns give it a natural resistance to creasing, making it one of the most travel-friendly fabrics in tailoring. So, feel free to pack your tropical wool suit in a garment bag during your next trip and simply give it a light steam upon arrival — it'll look as sharp as the day you packed it.
Seersucker is another classic summer fabric celebrated for its lightness of weight and trademark ‘puckered’ finish.
The fabric’s distinctive texture and hand-feel is actually the result of a unique weaving process, which alternates between smooth and puckered stripes, rather than a natural property of the cotton fibres. This unique weaving technique creating raised ‘puckering’ allows the fabric to stand away from the skin, permitting airflow between the fabric and its wearer.
In the summer months, seersucker is a fabric of choice for tailoring when lightweight, breathable materials are best. Today, you can also find casual shirts, shorts, and even swimwear made from cotton seersucker.
Seersucker's puckered texture means the fabric rarely lies flat against the skin — which is precisely what makes it so breathable. Embrace that same logic when dressing: wear it relaxed and unstructured, and let the fabric do the work.
Madras might be the least commonly spotted on the list, though it makes just as strong a claim as a stalwart warm-weather fabric as any.
This lightweight cotton fabric is woven from fragile, short-staple fibres that cannot be combed, only carded, due to their short length, which results in small bumps and slubs unique to madras. The madras pattern is a form of tartan design made with multiple vibrant colours and both sides of the cloth must have the same pattern.
Madras takes its name from the Indian city of Chennai (formerly Madras), the place in which the fabric was created. Due to its lightness of weight and bold colours, madras is primarily used to create casual summer garments like shirts and shorts.
The secret to wearing strong colours or patterns? It’s all about balance. Try pairing a bold madras shirt with some understated khaki cotton shorts or white linen trousers to ground the look, allowing the statement piece to shine.
Terms like “crisp hand-feel,” “puckered finish,” and detailed images can only take you so far — the best way to familiarize yourself with fabrics is to touch and experience them up close and in person.
