The Boeri Stinger is a wonderfully-designed helmet and it is owned by several of my little ski students. The Stinger has a top-of-the-line ventilation system and is very lightweight. My kids love this helmet! They say that it is comfortable and warm, and if it ever gets too warm on the slopes, they simply remove their ear-pads (I have had the chance to do this for them, and it is easy). The liner is made from anti-allergic materials. What I find very intriguing about the Boeri is that it only comes in two sizes, small and large. However, due to a well-designed adjusting system, the small helmet can be adjusted to four different sizes and the large helmet to three. There is an adjusting dial at the back of the helmet that can easily change between sizes. A great choice and available in the color designs Carbon, Snow Camo, Sassy (for girls) and Parade (for girls).
