Wendigo is lovely. He has all the majesty of antlers, but his is the smallest set I've used, and they're just WAY easier to wear. Not heavy, not wider than the shoulders, not so high as to cause problems in that direction. Just easy to wear and super impressive.
Wendigo wraps around the head, perfectly and comfortably distributing his slighter-than-you-think weight. Because of this his sizing is less flexible than our regular masks. He'll best fit a hat size of 7 or less (say a size small in the women's dept, if you don't know your hat size)
The wonder of a copper mask is in the strength and give of the material. Because it is so strong, the mask can be very thin- this makes it both very light, and makes it possible to fit as a second skin. These won't block your peripheral vision the way a leather. paper maiche, or plastic mask would. They can be very comfortably worn all day and night- no worries about sweat or rain causing them to soften and lose their shape. Rinse it with clean water at the end of the night before putting it away. They can stand up to anything you throw at them. As for packing? Throw it in your bag. If you're checking the bag, maybe stuff a balled up pair of socks where your forehead would go. Easy.
Not planning to wear your mask? He or she won't mind. They can hang flat against a wall, or sit on a shelf.
