I had one, and suffered a stupid fall into a big pile soft pile of leaves, kind of like a failure to clip out topple off at no speed and the shoulder bust open. Fair enough, I fell off so I taped it up. A month or so later I was dicking about in the snow and fell into a deep snow drift, the other shoulder bust open in the same way – nothing punctured it, it just split.
So I sent it back for warranty and Altura saud they didn’t cover their extreme mountainbike specific jacket for things of that nature.
Shortly after that the jacket delaminated and melted into a big sticky ball in the washing machine. I sent it back again and Altura’s response was that no one gets to try and warranty something twice. Wouldn’t recommend them.
