All things considered, for a $20 purchase, they are worth it.
Keep your eye out at end of season when Performance does their blowout warehouse sales. I picked up like 5 of the Headsweats for $2-$3 a piece in summer and winter weights.
I have an UnderArmour Cold Gear hood/balaclava that is indispensable in the winter. That’s it, let’s think COLD today! 
I have one with the tail you speak of. Don’t really see a difference either.
