Picked this up on a whim and it's become my go-to beanie for cold mornings. The acrylic knit is soft and the jacquard design gives it a fun retro lava lamp look without being too loud. One size fits most is accurate for me, though it's a touch snug at first before it relaxes. Keeps my head warm on walks and chairlift rides, and the skull cap shape stays put under a helmet. Not the thickest hat I own, but for the price and the pattern, I'm happy.
