Why FRONTIER¹?

1. Built from the inside

2 out of 3 founders are former Tier-1 operators, with over 25 years of combined operational experience. Not designed by a lifestyle brand — but by people who’ve lived it. For those who need performance, not promises.

2. Developed with experts, tested in extremes

Co-developed with Wageningen researchers and active military units. Used in every operational condition — arctic, urban, desert. Over 4 000 hours of research, testing and refinement, both in the lab and in the field.

3. A system, not a snack

400 kcal per bar. Ready to eat. No prep. No heating. 24+ month shelf life. Engineered to support full-spectrum human performance in field, downtime or deployment.

4. Certified, ethical, and accountable

IFS Food, ISO 9001, EU-made. Circular and Fairtrade where applicable. Full refund if not satisfied — and every piece of feedback gets acted on.
