Mammut Says No to Gorpcore, Targets Mountainwear Misuse with Help from DEPT®

Lately, metropolitan city streets have been filled with people wearing technical sports gear despite being very far away from challenging terrain. The style, known as ‘gorpcore’, is now a mainstay for the fashion-conscious, and that’s good news for some brands in the space. But not Mammut. The 162-year-old Swiss mountaineering brand is doubling down on its anti-gorpcore stance, which it articulated boldly in its ‘Not a Streetwear Brand’ campaign, with the launch of the tongue-in-cheek ‘Mountainwear Rescue’ follow-up, created once more by DEPT®. It positions the brand as the vigilant protector of technical outdoor gear, making a comedic argument against urban misuse and tapping into the playful tone that gently mocks city-dwelling gorpcore aficionados.

​Bel Moretti, creative director, DEPT®, says the new campaign “really felt like part two – we’d built such momentum with ‘Not a Streetwear Brand’ that when we saw cultural trends of people calling out the gear that had never hit anything harder than the pavement on social, we knew it was the right moment to respond.” The messaging evolved naturally, incorporating the social trend, putting the Mammut’s ‘we’re not a streetwear brand’ positioning into action, “encouraging people to set their mountain wear free of the city streets,” Bel adds.

Launched across the DACH, UK, and US regions, the star of the campaign is a delightful lo-fi film. The action-packed narrative sees Mammut’s representatives undertake a mission to confiscate technical wear from influencers and office workers. While the lo-fi aesthetic seems like a risky move on the surface, Bel says that it actually “reinforced authenticity” by contrasting with the “precision engineering at the core of Mammut” and the brand’s “passion for the outdoors and the environments the products are designed for.” Bel notes that the film’s “network of CCTV feeds, motion tracking, and the surveillance HQ underscored the rigour behind the brand, while the raw aesthetic mirrored the gear’s performance. Our trusted partnership gave us the confidence to prove that Mammut’s products don’t need polished gloss; their credibility speaks for itself.”

Anti-gorpcore sentiments have been popping up all over social media, but knowing when to lean into a conversation requires a lot of strategic nous. DEPT® was sure that this was more than a fleeting meme. “The best jokes hint at the truth,” says Bel. The team noticed “mountainwear was finally being retaken for real adventure, and people on social were taking their technical gear on ‘days out’ – we knew that while this content was dripping in irony, it was a sure sign people were ready for us to call them out and their mountain wear misuse in a funny, playful way. The audience is in on the joke, and that’s what makes it a powerful shared moment for Mammut to show off its core values.”

The wider campaign balances playfulness and brand authority, something DEPT® was comfortable riffing on thanks to the brand’s legacy and market positioning. “Mammut isn’t a brand built from 200-page personality docs but rather by people who live and
breathe its ethos. This gives it an unmatched ability to present itself authentically in the world in a multifaceted way. The people at Mammut are serious about the technical ability of the gear they create, and the idea of all that ability going unnoticed by the owner is like sitting in traffic in a car that can go 0-60 in 3 seconds. It’s funny so that we can be funny,” Bel explains.

The direct critiques of how consumers use mountainwear are bold and quite confrontational, with DEPT® treading a fine line between deepening loyalty among existing customers and not alienating potential ones. Bel says “the audience was ready – already knocking themselves across social for their wardrobes riddled with technical gear. For us, it’s not about following a trend but noticing a changing attitude. The people who get it are Mammut’s audience – they’re in on the joke and understand the irony.”

In an industry where many competitors embrace lifestyle crossover, an anti-gorpcore stance is a confident statement of the brand’s ethos and commitment to its USP. “Mammut isn’t, and never will be, a streetwear brand,” Bel states. “Our partnership is built on that principle. While competitors chase trends, we reinforce Mammut’s position as the uncompromising choice for mountaineers. That clarity builds long-term equity and loyalty that outlasts fashion cycles. When the hype fades, Mammut remains trusted by those who need gear for life-or-death conditions. This campaign crystallises that commitment: brand integrity over short-term sales, and products engineered for mountains, not overpriced coffee shops.”

Timing proved to be the biggest challenge for DEPT® while working on the campaign since social conversations can – and often do – fizzle out quickly. “We needed a bold enough statement to keep the momentum around giving mountainwear the life it deserves, while also nudging at the brands guilty of misusing it,” Bel says. The agency’s long-term partnership with the brand has made it possible, as they have been working together since 2023. “The trust and shared understanding we’ve built have allowed the first campaign to evolve naturally into this one. That foundation gave us the confidence to take creative risks and overcome challenges as one team.”
