Do you ship internationally?

Where are Thundernoise products made?

Thundernoise is designed in Sevilla, Spain. We work with European production partners and source heavyweight cotton fabrics for our signature drop weight and durability. Specific factory and certification details for each collection are listed on the product page when available.

How should I care for my Thundernoise garments?

Wash inside out at 30°C with similar colors, avoid bleach and tumble drying, iron on low heat. Heavyweight cotton garments may shrink slightly on first wash; we recommend cold wash and air dry to preserve fit and graphic prints.
