Cooling shorts

Two pairs of shorts. One promise: finish the workout, don’t cut it short.

The collection features our two TechCool™ sports styles, designed for summer heat. With a slim fit, stretch fabric, and dry-to-the-touch feel, the cooling sensation kicks in from the very first minutes and lasts as long as you’re sweating.

• Men’s Cooling Sports Shorts TechCool™: sizes S through 3XL, black, 150 grams, slim fit, UV protection.
• Women’s Cooling Sports Shorts TechCool™: sizes XS through 2XL, green, same technical stretch and breathable fabric.

Expand your outfit with the rest of the G-Heat cooling line:

• Cooling T-shirts TechCool™ or JadeCool™ to complete your upper body look.
• Cooling caps PolyCool™ to protect your head and the back of your neck.
• JadeCool™ cooling neck wraps to target the carotid artery without wetting the skin.
• JadeCool™ cooling towels for immediate recovery after exercise.
• Cooling arm sleeves for forearms exposed to the sun.
• All cooling accessories and the cooling apparel collection

In the summer, the lower body heats up first. Heavy thighs, sweat clinging to the fabric, legs that start to feel sluggish halfway through—you feel it long before you get thirsty.

Cooling shorts tackle the problem at its source. The TechCool™ fabric wicks away sweat and accelerates its evaporation, allowing the body to continue regulating its temperature naturally even when the thermometer soars. No water, no fuss, no technical breaks.

Three practical benefits in the field:

• Uninterrupted activity: keep up your run, family hike, or day of cycling without having to stop to catch your breath in the shade.
• S thermal safety: Avoid muscle overheating, which impairs concentration and precision of movement, especially on long outings during a heatwave.
• Freedom of movement: Don’t let the weather dictate your plans—head out properly equipped rather than canceling your outing when it’s 35 °C outside.

“The TechCool™ weave doesn’t cool your body—it helps it dissipate the heat you generate during exercise. You’ll feel the difference from the very first climb at 35 °C.” — Gwenaël Fournet, Technical Manager at G-Heat

The choice comes down to three simple criteria: gender, size, and intended use. Both styles feature the same TechCool™ technology and the same fabric (92% polyamide, 8% spandex): the cooling performance is identical.

Men’s style: slim fit, available in S, M, L, XL, 2XL, 3XL. Color: black—classic and versatile for both city and sports. Perfect for running, biking, hiking, and everyday summer wear.

Women’s model: slim fit, available in XS, S, M, L, XL, 2XL. Color: green—the collection’s signature shade. Same technical fabric, same lightweight feel (150 grams), same freedom of movement.

When it comes to size, here are two tips to avoid mistakes:

• Measure your waist circumference before ordering, then compare it to the size guide on each product page.
• If you’re unsure between two sizes, go with the larger one: the fit is snug, and shorts that are too tight compromise comfort and breathability.
• For intense workouts (running, CrossFit, trail running), your usual athletic size is generally the right choice.

In terms of use, these cooling shorts are just as suitable for athletic activities as they are for everyday tasks: hiking, walking, gardening, or a day at the beach. The stretch fabric doesn’t restrict movement, and the polyamide dries quickly after a rain shower or a quick shower.

Go out in shorts? Yes. Give up your activity? No.

Cooling shorts come in handy as soon as the temperature rises above 25 °C, for all types of activities. Five common scenarios have emerged from customer feedback:

1. Intense workouts (running, CrossFit, trail running, cycling): stretchy fabric, breathability, no preparation needed before exercising. Just slip them on and get started.
2. Family and leisure activities (hiking, sightseeing, beach, gardening): the cooling sensation lasts even when you’re stationary, and the fabric dries quickly after a swim or shower.
3. Daily commutes by bike or scooter: under your helmet or on the saddle, your legs stay cool and pedaling remains smooth all the way to your destination.
4. Low-intensity activities for heat-sensitive individuals (active seniors, Nordic walking, moderate-paced hiking): passive thermal regulation helps compensate for reduced heat tolerance.
5. Light outdoor work (professional gardening, outdoor activities, guided tours): for hot days when heavy PPE isn’t required and thermal comfort is key to productivity.

Just put them on. That’s it.

TechCool™ technology works dry, with no activation step required. No need to carry water, no need to reactivate at a water fountain, and no technical steps before heading out. The multi-layered weave manages sweat absorption and evaporation on its own: the cooling sensation begins as soon as your body generates heat.

Two practical tips to maximize the effect:

• Wear as a base layer, directly against your skin. The technology works on contact, not over thick underwear.
• Choose a snug fit in your actual size: the fabric should follow your movements without bunching, so evaporation remains consistent

Mild detergent, 30 °C, lay flat to dry. The rule can be summed up in a single line, but it’s key to preserving the durability of the technical fabric.

Polyamide and elastane do not tolerate high temperatures or harsh chemicals well. Here are a few precautions to follow:

• Machine wash at 30 °C maximum, on the delicate cycle, with minimal spin. Hand washing is still preferable to extend the garment’s lifespan.
• Mild detergent without fabric softener: Fabric softener clogs the technical fibers and reduces the effectiveness of the cooling fabric.
• Air dry, flat or on a hanger. Do not tumble dry: heat damages spandex.
• No bleach, no dry cleaning, no ironing. None of these treatments are compatible with the fabric’s composition.
• Store in a dry place: never store while damp to prevent mold, especially between two close-together outings
