This is a simple little present for a biker gent who is no doubt bored of socks by now!
It's knitted in the round in 6ply Regia variegated yarn. For extra stretchiness I've used a 2 x 2 rib pattern.
It will stretch to fit over his head but bounce back around his neck to keep out those cold winds that seem to have a talent for finding any exposed skin on a bikers face and neck.
I didn't count the cast on stitches but measured a similar gents head at the widest point and cast on enough stitches to stretch that far on the needle.
