Sometimes all you need is a solid black cap. Forget your team allegiances, you simply can't go wrong with Killspencer and New Era's new collaboration. The two brands have teamed up on a collection of three hats that you can purchase in their performance wool or in either a snap back or fitted cap with a full grain leather brim. It's luxury without overdoing it in the most casual staple you can own.
