Dolly is a puzzle. While these arm warmers are clones of the original Dolly, the original Dolly was no clone, nor did this Dolly get its wool from that Dolly. Who was not on first. Don’t ask about second.

In terms of performance, these Dollys are unlike previous warmers by Swobo or anyone else. It’s the first example we know of where the hydrophobic inside is wool and the hydrophilic outside is nylon. Not too many arm warmers take advantage of hydrophilic/phobic threads. The idea is simple. The skin will feel warmer if it’s not clammy with sweat. The sleeves will take the sweat off the skin and put it on the outside where it can evaporate faster, leaving the arms dry and toasty. Sizes are small through XL. The color is black. Machine washable.
