Ever feel like your neck is sore from rubber necking? No wonder: the average human head weighs between eight to twelve pounds. So, image how heavy a bowling ball is. Heavy isn't it? A bowling ball weighs between 9 to 16 pounds. Yep, that's what your neck is supporting. So, proper posture is very important! A neck rest is great for supporting that big brain of yours on your epic adventures. Some folks may think its a head rest but that is a misnomer. The neck rest should be positioned between the bottom of your helmet on your neck and collar bone.
