Summer Trousers

For those tackling steeper climbs in warmer climates, our summer hiking trousers offer the perfect balance of protection and ventilation. We use high-tenacity, snag-proof fabrics to allow for maximum airflow without sacrificing the durability required for the peaks. These trousers feature four-way stretch, ensuring unrestricted movement on every scramble, making them the essential choice for your next summer expedition.

Lightweight & Breathable

When the heat is on, your gear needs to work harder. Unlike traditional, heavy outdoor gear, these summer trousers offer a lightweight feel while providing a durable barrier against the elements. It’s the ultimate solution for those looking for breathable trousers that transition perfectly from a breezy coastal path to a sun-drenched cafe.

Packable & Practical

Designed for the modern adventurer, our summer trousers are a travel essential. The featherlight fabric is naturally crease-resistant and easily packable, making them perfect for stuffing into a hiking backpack for weekend trips. Whether you’re exploring local trails or packing for a trek in a tropical climate, our summer range ensures you stay protected from UV rays and insects while staying as cool as possible.

Frequently Asked Questions (FAQs)

Do these lightweight trousers have UV protection?

Yes. The technical weave of our trousers provides a natural physical barrier against the sun’s rays. Unlike standard fashion leggings or thin cotton, our performance fabrics help protect your skin during long days on exposed ridges or coastal paths where shade is limited.

How do I care for my summer trousers?

To maintain the moisture-wicking and breathability of your lightweight trousers, we recommend washing them at 30°C with a technical wash. Avoid fabric softeners. Air drying is best to preserve the integrity of the stretch fabrics.

Can I wear summer hiking trousers for technical climbs?

Yes. While our summer trousers are lighter than our winter range, they are engineered with the same abrasion-resistant technology. They provide the necessary protection against brambles and rocky outcrops while ensuring you don't overheat during strenuous activity.
