Outdoor Trousers for Every Adventure

From forest trails to urban commutes, our ladies' outdoor trousers are built for life on the move. We understand that your day doesn't always follow a linear path, which is why our gear is designed to look just as good in the coffee shop as it does in the countryside. Engineered with moisture-wicking technology and a breathable finish, these trousers ensure you stay comfortable regardless of the activity.

How to Choose Your Perfect Outdoor Trousers

With so many options, finding the right pair depends on your outdoorsing style. For those focused on serious elevation and rugged terrain, we recommend our dedicated women's hiking trousers. However, if you need an all-rounder for dog walking, travel, or everyday wear, our signature MAX Stretch Skinny Outdoor Trousers are the perfect place to start.

Durable and Sustainable

At ACAI, sustainability isn’t just a buzzword, It's part of our DNA. Our women's outdoor trousers are crafted using eco-conscious methods, including PFC-free water-repellent treatments that protect the environment while protecting you from the elements. By investing in high-quality, snag-proof kit, you’re choosing a more sustainable way to shop. Buying gear that lasts for years of adventures.

Frequently Asked Questions (FAQs)

Do your outdoor trousers have pockets?

Absolutely. We know how important utility is, so our trousers feature strategically placed, secure pockets. Most of our styles include a discreet zipped pocket, perfect for keeping your phone or keys safe while you’re out.

How do I care for my outdoor trousers to maintain water resistance?

To keep your kit in top condition, we recommend washing at 30°C with a specialist tech wash. Avoid fabric softeners, as these can damage the technical fibres and reduce the effectiveness of the water-repellent finish. For more tips on keeping your gear performant, read our guide on Waterproof vs. Shower Resistant Outdoorwear.

Are these outdoor pants suitable for all seasons?

Our core range of women's outdoor trousers is designed for year-round versatility. They are highly breathable for summer use but provide enough wind resistance for autumn. For the colder winter months, we suggest exploring our thermal outdoor trousers, which feature a cosy fleece lining to keep the chill at bay.
