Erik is a narrow cap with a moderately deep fit. The brim is slightly separated from the body of the hat, which is sewn down (no snap). The main body is one piece with a beautifully matched slimming seam in the back - that perfect V in the back view of the light blue, loden, and sapphire (the overall pattern of the green doesn't allow for a book match back). The sides are constructed with an elegantly curved panel, making a close fit with minimal bulk. All four color options are heritage-quality Harris Tweed wool.
