In running, dressing for the warmer months means eliminating the discomfort of heat and sun while keeping all the benefits. You need to combine lightness and moisture wicking, while maintaining the right sporting properties — in particular optimised muscle support. A full breakdown of what to wear in summer when running trail or in other disciplines.
Lower body: shorts are the way to go
When the warmer days arrive and the early-morning chill is no longer a concern, running shorts are the way to go. Either way, choose a close-fitting garment with compression and muscle support to improve performance and prevent cramps and muscle pain. When it comes to running shorts, go for lightweight and comfortable options — ideally with a micro-perforated fabric that allows gentle, effective ventilation to stay dry during effort while delivering a genuine feeling of lightness.
The 3D-FLEX® range from CIMALP is positioned at the premium trail segment. It was developed with the input of doctors and physiotherapists specialising in high-level sport, and meets the needs of trail runners looking for performance.
It offers compression and muscle support for real performance gains and genuine prevention of cramps and muscle pain. In addition, these shorts allow greater freedom of movement thanks to the highly stretch 3D-Flex® 200 fabric, which is thicker for optimal use in slightly cool conditions. Finally, the
'SmartDry' fibres provide optimal moisture regulation to keep the body cool and dry, delivering perfect running comfort even in intense heat!
Upper body: a breathable t-shirt
In sunny conditions, opt for t-shirts or vests that give your arms freedom of movement without restriction. Choose quick-drying materials to ensure better comfort and effective moisture wicking. Bear in mind that white reflects light, and go for specific tops: they are made with special seams that prevent chafing.
The combined comfort and lightness of a versatile t-shirt in technical, lightweight Smart-Dry knit offers perfect moisture management and better odour control thanks to an ionisation treatment. With its specific knit and a highly stretch piqué construction, the matte surface of this quality t-shirt ensures an ultra-soft, comfortable feel combined with excellent moisture transfer for breathability.
Furthermore, the offset flat seams "flat lock" construction helps prevent chafing for sensitive skin and contributes to enhanced comfort.
Running socks: a true comfort essential
In the sun, don't head out for a run without socks! They are essential for good foot support, and if you choose carefully, you'll also get a genuine feeling of freshness.
Make sure you choose socks with flat seams, a reinforced heel and ideally models with a right foot / left foot ergonomic design. And of course, the material must be breathable to wick perspiration effectively.
With socks made from COOLMAX® fibres, you get a guaranteed cooling effect and a great sensation of lightness with these models designed for intensive use.
A cap for proper protection
Finally, don't forget to protect your head effectively when it's warm and you're out running! Lightweight running caps are ideal — light, airy, breathable and premium in construction: they offer real comfort, zero irritation and disappear completely during effort!
This cap is highly breathable and dries quickly so perspiration never becomes a nuisance. It also offers significant sun protection (UPF50). Finally, in the evening or early morning, reflective prints keep you clearly visible even in low-light conditions.
Now that you're all set for the warmer months, check out what to wear when running in winter and cold weather.
