I only glanced through the book, but also noticed the cute snowboard design pages and the snowboard speak. This seems pretty awesome compared to the normal books. Lots of extra stuff in there as well as the usual story.
Cute outfit. I worried it'd be much thinner than it looks but it has a nice fluffy padded quality. Not sure what the pants fabric is but it's an unusual texture I don't recognize - it's not the shiny waterproof material it would be made of if it was made for humans.
MrsMac mentioned the belt around back - it is only sewn in one place, but I tugged at mine and the sewing seemed pretty sturdy. I think your kid's going to have to really try to yank it off for it to be a problem. The snap on the belt is pleasingly easy to undo for such a small one - not stiff at all, so hopefully little fingers won't have problems.
One of the two gloves was really a pain to get on. Not both of them, just one. It was really tight, and I had to pinch one edge against her wrist while I stretched it over all her fingers and it kept slipping.
Someone asked if the pants were quilted. They're not but there is some stitching on the front that's there...to give it some shape? I'm not really sure, honestly. There's none on the back: (front) (back)
I do wish the boots could be ordered with this outfit as well as with the snowboarding accessories.
