Moving to China is not a problem in itself, but reducing quality of material and workmanship is.
Mammut is buying everything they can.
Sometimes nothing changes. For example the old "Biwell" shoe wax is still the same, only wrapped up different.
With Ajungilak it was different.
The german branch of Ajungilak, seated in Hamburg, designed the sleeping bags. And they where real experts. fantastic design and very high quality of the materials. The old lining, for example, made from Nylon and Viscose, was one of the best ever.
But Mammut bought the name "Ajungilak" and offered the folks from hamburg to move down south to their headquarter.
They refused.
And without the knowledge the brand Ajungilak took a dive. They are a little bit better now then in the beginning and thankfully they left some classics, like the Tyin, more or less unchanged.
But, as usual, they now offer every year a "new and improved" range of exactly the same stuff as the year before.
Thats the way to make money: lots more different models, change the appearance evry year, reduce quality gradually, have incompetemt hacks from outdoor magazines write favourable reviews.
Only people with a longer memory span will know the difference.
