In sweltering heat, style often hangs by a thread. More precisely: by the fibre. As soon as the thermometer climbs past 30°C, cut and colour take a back seat. What truly matters for staying cool all summer is your outfit's ability to let air circulate and wick away moisture.
When it comes to staying cool, the choice is clear: on one hand, synthetics that suffocate and trap heat; on the other, natural fabrics that breathe and move with you. At Hast, synthetics are strictly excluded. For our new Spring-Summer collection, we focused on naturally cool, lightweight, and elegant fabrics.

Linen: the champion of ultimate ventilation
If only one could remain, this would be it. Linen is the quintessential summer fabric, and it is no coincidence that humanity has favoured it for millennia.
Why is linen so breathable?
The magic of linen lies in its structure. It is a remarkably thermoregulating natural fibre: its hollow fibres act as a natural insulator against external heat, while remaining exceptionally porous. Linen absorbs moisture without ever feeling damp to the touch, and dries in moments. The result: an imte cooling feel against the skin.
How to wear it this summer?
Forget the clichés of rumpled, shapeless linen. At Hast, we work with premium linens that develop a superb patina over time. A linen shirt with rolled-up sleeves or lightweight linen-cotton trousers will see you effortlessly through from the office to evening drinks on the terrace.

Wool fresco: breathable tailoring elegance
Pairing "wool" with "heatwave" might seem counter-intuitive. Yet wool is one of the best-kept secrets of the well-dressed gentleman in summer, provided you choose the right weave: fresco.
What is wool fresco?
Fresco (from the Italian affresco - fresh) is a worsted wool fabric crafted from high-twist yarns woven into an open plain weave. This technique creates an exceptionally porous and "open" cloth. Hold fresco up to the light, and you can see daylight through the weave. Air circulates freely, while the wool wicks away moisture and remains effortlessly crease-resistant.
The ideal choice for formal tailoring
It is the ultimate cloth for anyone needing to wear a suit or stay sharp despite soaring summer temperatures. Fresco trousers or a fresco jacket guarantee flawless hold from morning to night, without any heaviness.
Cotton poplin: everyday softness
If you are looking for a versatile, accessible fabric offering absolute comfort for daily summer wear, cotton poplin is your best ally.
The qualities of poplin
Cotton poplin stands out for its tightly woven fine yarns, lending it incomparable lightness and smoothness. At Hast, we select long-staple cotton to ensure a fine yet durable fabric. Naturally breathable and gentle on the skin, poplin prevents that uncomfortable "clinging" feel when the sun is out.
The foundation of your weekday wardrobe
A fine poplin shirt in white or sky blue remains the cornerstone of both men's and women's wardrobes. Paired with lightweight chinos, it delivers a sharp, clean look, perfect for navigating heatwaves at the office.

Ecovero: eco-responsible drape
For those seeking lightness, ease of movement, and a touch of modernity, we have introduced Ecovero into our summer collection.
What is Ecovero fibre?
Ecovero is a certified eco-responsible viscose, derived from wood pulp sourced from sustainably managed forests. Technically speaking, this artificial fibre of natural origin boasts remarkable properties for summer: it is exceptionally fluid, silky, and thermoregulating. It glides effortlessly over the skin without clinging, providing an instant cooling sensation alongside a clean, airy drape.
For relaxed summer silhouettes
Ecovero excels in fluid pieces such as Cuban collar summer shirts or relaxed casualwear. It is the ideal fabric for bringing breezy lightness and relaxed character to your holiday wardrobe.
A final word
When facing a heatwave, relying on synthetic fabrics (polyester, nylon, acrylic) is a sure way to suffer through the day. By choosing natural fibres and smart weaves like linen, fresco, cotton poplin, or Ecovero, you invest in garments that respect your skin and stand the test of time.
Our entire new Spring-Summer collection was designed with an uncompromising focus on coolness and longevity. All that remains is to pick your allies against the heat.
