From "An instructive back and forth with Mountain Equipment on their Aetherm Precision Insulation"
Email Exchange with Mountain Equipment (From October 2024)
We occasionally write to manufacturers (we like) when we feel they're in the process of blundering or could make a meaningful improvement. The purpose of publishing our side of this email exchange with Mountain Equipment is not to shame them in any way or even criticise any of their products. Rather, the purpose here is simply to use Mountain Equipment to highlight a broader problem in the outdoor industry; a problem we addressed in our piece: Insulation: A Fraud of Meaningless Measures.
This respectful interchange with Mountain Equipment is posted here as an addendum to that piece, to show how the lack of any EN testing standard for measuring synthetic insulation, causes brands like Mountain Equipment to make claims they cannot back-up publicly with technical data.
