Your kid may think hes invincible, but you know better. Get him the Mammut Tripod Climbing Kids Helmet for a little added safety on the rocks. Thanks to inmolded construction, this Mammut helmet weights a scant 7.4oz, so he wont even notice its on his head when he climbs. This isnt some scaled-down featureless brain bucket. The Tripod Kids Helmet includes the same venting and excellent adjustment system as the adult model.
