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.

(From Hammer Nutrition SV Winter Beanie customer) The winter beanie fits perfectly under my helmet, keeps my head warm, and wicks away sweat. I didn't think I could love a beanie this much.

(From Hammer Nutrition SV Winter Beanie customer) This beanie is absolutely perfect for chilly workouts. The hat is very comfortable and remains comfortable when soaked with sweat. However, it could be longer because I found it rode up over the bottom half of my ears when paddling. Also, this hat, for me, is for air temperatures of 45 degrees and up. On a really brisk morning this hat was not able to fight off the cold to my liking. The comfort level is tops tho! Perfect for the season between baseball hats and wool beanies.
