The Terra Helmet from MET is an entry/mid range mountain bike helmet designed for trail and all-mountain riding.

Mountain bike helmets can normally be distinguished by the presence of a front visor and additional protection around the rear of the head.
It is important to buy a mountain bike helmet that is a snug fit as the last thing that you want is for your helmet to move around when you’re flying down a steep descent. 
Finally, if you’re going to be riding in warmer climates, look for a model that features generous ventilation vents to ensure maximum cooling airflow at low speeds (for when you’re climbing).
