BOULDER, Colorado (June 2, 2026) – Mammut, the Swiss mountain sports brand with more than 160 years of alpine heritage, is partnering with the Appalachian Trail Conservancy (ATC) to support the organization’s “Take a Hike” campaign and Definition Petition. The nationwide effort seeks to reclaim the phrase “take a hike” from a dismissive gesture into an inviting call to reconnect with the outdoors. The partnership reflects Mammut’s core mission of making gear that inspires more people to get outside.
Through the collaboration, Mammut will contribute $1 for every signature added to the Take a Hike Definition Petition (now through August 2026), unlocking funding to help the ATC protect and care for the Appalachian Trail. The petition calls on major dictionary publishers, including Merriam-Webster and the Oxford English Dictionary, to add a modern, positive definition: A friendly invitation to reset, recharge, and reconnect with the outdoors.
“With Mammut’s support, every person who signs the petition helps to protect the Appalachian Trail, and helps to rewrite the definition of ‘take a hike’ to reflect the mental, physical, and emotional benefits of hiking,” said Caroline Ralston, Associate Vice President of Marketing and Communications for the ATC. “We’re incredibly grateful to Mammut for standing with us. Their support advances our efforts to ensure the Appalachian Trail and its landscape are always protected, resilient and connected for all.”
For over 160 years, Mammut has created technical mountain gear to enable more people to experience the outdoors safely and confidently. Partnering with the ATC extends that legacy from high alpine environments to the forests, ridgelines, and communities along the 2,190-mile Appalachian Trail, inviting more people to discover the Trail while helping safeguard it for future generations.
The partnership builds on Mammut’s “Take a Hike” brand campaign, which channels online negativity into something healthier: going for a hike. The campaign uses an AI chatbot named Cliff to intercept moments of online negativity and invite people to log off and “take a hike.” Inspired by research on the mental and physical benefits of nature, the campaign reframes hiking as a modern, science‑backed form of self‑care and a healthier alternative to doom‑scrolling.
“Our partnership with ATC is an invitation to lace up your boots and hit the trail,” said Matt Kaplan, Managing Director of Mammut North America. “We want to help more people step away from their screens, reconnect with the natural world, and feel the mental and physical benefits that come from even a few hours outside. When someone signs the petition and heads outside, they’re not only doing something good for themselves – they’re helping protect one of the most iconic hiking routes on the planet.”
Mammut and the ATC are inviting everyone – from seasoned thru-hikers to first‑time day hikers – to join the movement:
