The "Boundary" beanie by Columbia is a fantastic hat for those who like a bit of extra protection in snowy conditions. The curved visor helps keeps snowflakes or sleet or rain off and this is particularly useful for those who wear glasses. The Boundary looks cool too. This hat is really snug with an 85% acrylic/15% wool yarn mix for superb warmth and durability. This is a hat you'll just love to wear.
