Mammut, the Swiss-based outdoor brand that is part of the Conzzeta group, says it is aiming to eliminate poly-fluorinated chemicals (PFCs) from its entire product range by 2025. As part of this program, for spring/summer 2020, 65 percent of all sleeping bags will be PFC-free, compared with a ratio of 35 percent this year. The share of PFC-free products in the brand's range of backpacks, bags and climbing harness is increasing from 26 percent in the 2019 spring/summer season to 47 percent in spring/summer 2020. Mammut has invested in the development of alternatives to PFCs and is participating in a two-year research project, called Popfree, led by the Research Institute of Sweden (RISE). Popfree's goal is to “create a transition in sectors using PFAS to feasible non-fluorinated alternatives.” Additionally, Mammut has conducted more than 400 tests on 120 different materials used in its products. In January, Mammut joined the Sustainable Apparel Coalition (SAC), the clothing, footwear and textile industry alliance for sustainable production.
