GrandTongo Brand Guide

GrandTongo Brand Overview and History

Founded in 2015 by a team of outdoor enthusiasts and chemists frustrated with the harsh side effects of traditional DEET-based repellents, GrandTongo set out to create a superior alternative. Drawing inspiration from nature's own defenses and cutting-edge science, the brand pioneered Picaridin-formulated sprays that match DEET's efficacy without the greasy residue, strong odors, or skin irritation. Headquartered in the Pacific Northwest, GrandTongo has grown from a small startup to a trusted name in the Health & Household sector, specifically Insect & Pest Repellents under Body Treatments > Sprays. With a commitment to sustainability, all products are cruelty-free, paraben-free, and packaged in recyclable materials. Over the years, GrandTongo has earned accolades for innovation, including awards from outdoor gear magazines, and maintains a loyal following thanks to consistent 4.4/5 ratings across its core lineup.
