I love the looks of these sunglasses and they are comfortable but it seems like UA sunglasses are all plagued by nosepieces that get brittle after average use. Search for Under Armour nose piece and see all the returns. I called them and they transferred me to the manufacturer to see if they could help...they were closed so only time will tell, but they are not quickly replaceable like Oakley's or others.
