Materials

At FIELDTEST, we are dedicated to using the best quality and most sustainable materials in the production of our sleeping bags. To ensure that our materials meet our high standards, we subject them to rigorous field and laboratory tests, including compliance with ISO 23537-1:2022 point 5.1 certification.

We carefully source our materials to ensure that they are of the highest quality and meet our strict sustainability requirements. In addition to our own testing, we work closely with our materials suppliers to ensure that they share our values and commitment to ethical production practices.

We are especially proud to use VALTHERM ZERO DOWN synthetic insulation line in our sleeping bags. Why? After numerous tests with all other and well known brands, we came to conclusion, that this material is offering the best thermal insulation and breathing characteristics. It is also super durable and easily retains its original shape.

We believe that sustainable production practices are essential to protecting our planet and ensuring a better future for generations to come. That's why we are committed to working towards a more sustainable future by reducing our carbon footprint, increasing our use of renewable energy sources, and using only the most sustainable materials in the production of our sleeping bags.
