MAMMUT, the Swiss outdoor brand, is releasing a capsule collection made with Japanese select shop BEAMS to celebrate the retailer's 50th anniversary. It goes on sale Friday, October 23. The centerpiece is a reissue of the original Serac Extreme Jacket, which first appeared in 1995.
That original is remembered as the jacket that protected young alpinist Stephan Siegrist from severe weather when he took on the rugged mountains of Patagonia in December 1995. It later became the starting point of MAMMUT's top-tier Eiger Extreme line. The new Serac Extreme Jacket BEAMS Special follows the original design closely while adding modern performance through a GORE-TEX build. A large MAMMUT logo sits on the left sleeve and an embroidered BEAMS logo on the right. Inside are a special "Eiger Story Label" and a reissued brand label. It comes in orange and blue, in sizes S to XXL, at 121,000 yen including tax.
Two companion pieces round out the collection. The Serac Extreme ML Crew Neck sweatshirt is offered in gray or black, sizes S to XL, for 18,700 yen. It carries large prints of both brands' logos on the back, with the words "SERAC PROJECT EXTREME" and the MAMMUT logo on the chest. The Serac Extreme Cap, in blue or black, costs 7,700 yen. It is embroidered with both logos, and an adjuster strap at the back sets the fit.
The collection is sold at select BEAMS locations in Japan: BEAMS Harajuku, Nagoya, Life Yokohama, Hakata, Street Umeda, Sapporo and BEAMS Japan. It is also on the BEAMS online store. The release is a Japan-based launch, and the reports do not list any New York retailer. For readers in New York who follow outdoor and street fashion, it is a notable pairing of a Swiss mountaineering heritage piece with Japanese select-shop culture.
