Yes!
Snuggle your head — and everything within it — inside a warm wool Klein Bottle Hat.
Pop an Acme Klein Bottle on your head!
It’s ideal for skiing, sleigh-rides, snowball fights, midwinter colloquia, Antarctic beach parties, and alpine chess tournaments. A perfect gift for anyone with a zero-volume head. An important accessory to the one-sided mind. An essential headwarmer for your non-orientable friends who are temporarily immersed in our 3-dimensions.
This Klein Bottle is hand knitted, so it’s seamless and perfectly contoured. It’s constructed of knit-purl-knit-purl, so the "outside" has the same pattern as the "inside". One sided? You betcha!
