Stretchy Polartec® Power Shield™ fleece adds insulation to your helmets.

Vented helmets are great for summer outdoor adventures but once the cool drizzle sets in it's tough to find something that both insulates and fits beneath your climbing and cycling helmets. Enter The North Face Ascent Beanie. This abrasion-resistant and highly lightweight cap features a thin stretchy layer of single-sided Polartec® Power Shield™ so it fits close without feeling too tight against your ears or forehead. It also folds down and compresses nicely so you can stick it in a pouch or back jersey pocket once the sun starts to warm you up.
