I recently took up snowboarding, and was looking to get something I could wear under a snowboarding helmet.

Pros:  The product seems to be well-constructed from high-quality material.  While I did not actually wear it outside in the cold, I am pretty certain that it would take some pretty extreme conditions for the wearer to have a cold neck and head.  By itself, the product felt comfortable to wear when I tried it on.  The detachable face (nose?) mask was nice.

Cons:  To secure the balaclava to your head, you have to velcro it shut.  The velcro isn't shown in the product image (as of 2/17/12), and that side of the balaclava is very bulky and asymmetrical.  I expect that the position of the velcro strips on this balaclava would cause an uncomfortable fit under a snowboarding helmet. Additionally, the awkward velcro makes the balaclava look very ugly to wear.  Looks aren't everything, but they ARE something.

Result:  I am returning the balaclava in favor of a (less expensive) Chinook face mask.
