Commonly asked questions.

Which iron do I use for heat-sealing? 

What is heat sealing? 

    • All our fabrics have a technical coating called thermoplastic polyurethane (TPU). This coating makes it possible to essentially stick the fabric together without having to mess around with glue! The TPU coating can be activated when heated with hot air or an iron.
