What Our Gearhead(R) Experts Are Saying:"The Balaclava 2. 0 sat perfectly under my helmet without shifting once through a three-hour ride in the low thirties. The Polartec AirCore panel on the front cut the wind completely, and the fleece backing felt genuinely soft against my face the entire time."The Balaclava 2. 0 from Castelli solves the cold face problem without bulk or fuss. Polartec AirCore on the front handles wind protection while the warmer fleece interior wicks moisture and stays soft through long efforts. The stretchy face opening adjusts to cover over the nose, over the mouth, or tuck under the chin, depending on conditions, and the whole thing sits comfortably under a helmet without adding pressure or shifting out of place.
