Made from 97% Cotton and 3% Polyester, this red and blue, duck-billed baseball cap features a red bill and a raised and embroidered, Captain America shield symbol adorning the blue of the cap. This baseball cap is very similar to our Captain America Red Blue 39Thirty baseball cap, but there is one, minor differential: this cap features an embroidered Marvel Comics logo adorning the back, unlike the other, which features a smaller Captain America shield. Anyway, the cap we're presently describing is part of New Era's line of high quality, 39Thirty baseball caps; the proof is evident in the official, 39Thirty seal adorning the bill. Yup. Oh, I should also mention the covered, elastic headband lining the inside of the hat for a secure and comfortable fit. And...this hat is specifically sized, so....know the girth of your noggin before adding to cart.
