We believe great products start with strong values. That’s why our manufacturing emphasizes transparency, long-term partnerships, and a people-first approach. We prioritize fair working conditions and sustainable practices, backed by our B-Corp certification.

We choose manufacturing partners based on verified social audits, assessing fair wages, safe conditions, reasonable hours, and workers’ rights. This ensures our products meet high ethical standards.

By building lasting relationships with trusted suppliers, we maintain control over our supply chain and work only with those who share our values—delivering outdoor-ready products with minimal environmental impact.

Care Instructions:

Close all fastenings before washing. Use a gentle cycle at 30°C. Avoid bleach, chemicals, and fabric softeners. Tumble dry on low heat and iron at a low temperature if needed.

Our technical fabrics are designed to perform; fabric softeners interfere with their breathability and water-repellent properties, so skip them.

For insulated pieces, tumble dry separately on low heat with a few tennis balls to help restore the loft. No dryer? Give the garment a good shake and gently redistribute the filling by hand.
