I like the hat . Looks and feels good.
This is my second Alter Ego hat and I can't say enough good things about it. I have a large head - fitted size 8 - and I never get snapbacks because I always end up with it set on the very last hole and it looks stupid from behind. With the XL size from Alter Ego, I have only 2 holes exposed! The fit is perfect. The material is excellent and very, very lightweight. The construction and stitching is very good. I highly recommend Alter Ego hat especially the Cruiser Splash! My only nitpick is I wish they had XL in all of their Christmas hats
Another banger just in time for some winter miles. Needed something to go with all of the winter layers that happen to be mostly black and this fit the bill. The Cruiser Splash has a consistent, no bounce, barely there fit that I love. This is number 6 of the collection and I couldn’t be happier!
