A close fitting, stretchy, mountain Beanie

Mammut says

The Aenergy Beanie is a helmet-compatible and lightweight functional beanie that is a perfect mountain companion. A combination of stretchable material and an anatomical cut means the beanie is a great fit and is very comfortable to wear. The laser-cut slits make it easy to secure your goggles.

Our Verdict

Mammut’s Aenergy Beanie is a perfect under helmet beanie that provides a close fit and low bulk so it doesn’t feel uncomfortable while wearing a helmet or goggles.

The one size they have this in is a very close fitting size on me.
