From Andy Burnham’s casual political image to the Paris fashion crowd, jeans remain a symbol of confidence, familiarity and masculine style even when temperatures soar.
As Britain and much of Europe sweltered through another spell of punishing summer heat, one item of clothing refused to disappear from men’s wardrobes: jeans.
In theory, denim should be one of the first casualties of a heatwave. It is heavier than linen, less ventilated than shorts and often unforgiving under direct sun. Yet from city streets to political photo opportunities and the front rows of Paris fashion week, many men continued to wear jeans as if the weather had no vote in the matter.
Greater Manchester mayor Andy Burnham became an unlikely reference point for the trend. His familiar “cool dad” look — relaxed jeans, simple tops and understated casualwear — has helped shape a public image that feels approachable rather than overly styled. During the UK heatwave, that same denim uniform stood out as both practical branding and stubborn habit.
The phenomenon was not limited to British politics. In Paris, where the menswear calendar unfolded under extreme temperatures, many members of the fashion crowd also stayed loyal to jeans. Even as organizers tried to soften the heat with shade, fans, misting systems and adjusted showtimes, denim remained visible outside venues and on the city’s streets.
The persistence of jeans says something deeper about menswear. For many men, denim is not simply a fabric choice; it is a comfort zone. Jeans offer structure without formality, casualness without appearing careless, and a sense of identity that shorts do not always provide. They are easy to style, socially safe and rarely require much thought.
Shorts, by contrast, remain surprisingly complicated. Some men see them as too informal, too exposed or too difficult to wear well outside holidays, parks and weekends. In professional or semi-public settings, shorts can still feel like a risk. Jeans, even in the wrong weather, often feel like the safer option.
Fashion experts argue that this loyalty is tied to ideas of masculinity, control and self-presentation. Denim has long carried associations with workwear, rebellion, utility and understated cool. A man in jeans can look relaxed without seeming dressed down, rugged without trying too hard, stylish without appearing too fashion-conscious.
Retail trends suggest the attachment is not fading. Rugged denim brands and workwear-inspired labels have continued to perform strongly, even during warmer months. The appeal of names such as Carhartt, Edwin and Nudie lies partly in their promise of durability and authenticity — qualities that remain attractive even when the weather makes lighter clothing more sensible.
There is also a practical argument, though a limited one. Some denim, especially lighter cotton styles, can be breathable enough for moderate heat. Loose cuts, pale washes and softer fabrics can make jeans more wearable in summer, while full-length trousers also protect legs from sunburn and city grime.
But the broader point is cultural. Heatwaves are forcing Europe to rethink clothing norms, public infrastructure and daily habits. Offices, transport systems and fashion events are all being tested by temperatures they were not designed to handle. In that context, men’s refusal to give up jeans becomes a small but telling sign of resistance to change.
The summer wardrobe is evolving, but slowly. Linen trousers, relaxed tailoring, sandals and technical fabrics are gaining ground. Still, denim’s hold remains powerful because it solves a problem that is not only climatic, but psychological: what to wear when a man wants to look casual, credible and in control.
In the end, jeans may be irrational in a heatwave, but they are emotionally logical. They offer certainty at a time when the weather, fashion rules and public life all feel increasingly unstable. For many men, that is enough reason to keep wearing them — even when the temperature says otherwise.
