These tubes of material are awesome. If your head is too cold, wear a Buff. If your head is getting sunburnt, wear a Buff. If your neck is all yucky sweaty, wear a buff. If your hair is in the way, wear a Buff. If the mozzies are attacking your face, wear a Buff.
We'll be carrying the original Buffs, plus the UV coolmax ones, plus the windproof ones, plus the fleecy warm ones. That's our heads sorted.
