I just bought a pair of Oakley Radar Locks a few days ago and noticed that the Soft Vault case the Radars came is has a weird chemical smell right out of the box. It's most likely the foam padding inside the upper part of the case. These are the regular M Frame/Radar cases (with one slot for the glasses and extra slot for a second lens) and my old ones never had this smell. I've been trying to air them for 2 days but the smell doesn't go away. What could it be? Would it be worth trying to exchange them for another case at my local O Store? I bought them online from an authorized Oakley retailer four days ago, and I don't feel like shipping the case back for a replacement (and it's not the seller's fault for sure).
