I find this beanie to be ideal for riding in temps between 30 and 50. It blocks enough wind to keep me warm, but lets enough air through to keep me dry.

Love my SweatVac Winter Beanie. It takes up minimal space in my jacket pocket and is warmer than my bulky Patagonia beanie. A definite must purchase item for anyone spending time outside this winter.

Love this material. Excellent warmth to weight, and sweat management is off the charts. Keeps the brain warm for all activities.

(From Hammer Nutrition SV Winter Beanie customer) Online pictures simply don't do this hat justice. It is the perfect winter sweaty activity hat!

(From Hammer Nutrition SV Winter Beanie customer) This is the second of these hats I have, they are great in varied temps from 35 to 65 my head doesn't get cold or overheat.
