This black Mammut black Avers logo crew neck sweater has been crafted from breathable and comfortable polyester blend and features long sleeves, a partly bonded kangaroo pocket, white logo text at the chest and back of the neck and bias tape as a design feature. The phrase 'avers' is used to describe an act of asserting of the truth. We have something very important to assert. This Mammut jumper is phenomenal, and you should try it for yourself.
