This is called the "Peekaboo Beanie Cap"
Another winter time selection from BioWorld in 2021, this is a smooth-texture fabric beanie-style hat. It has a wide cuff/base, and an embroidered design. The whole hat is a darker blue/nearly navy-blue. The embroidered neoclassic Sonic is placed so that he is covered by the cuff of the hat up to about the waist. Having a character design that's 'popping up from' something like a cuff, a pocket/etc. is a fun idea. Here, he's sort of pointing with a hand on one hip. This is a fun hat with a design that stands out.
