Federation mobile suits such as the RX-78-2 Gundam and the GM, as well as Zeon mobile suits like the Dom and Zaku II, have graced the slopes either skiing or snowboarding.
The group will be heading to other ski resorts in Japan throughout the winter season, and they will still be wearing their Gundam costumes while doing so.
There are also some not from the Universal Century, such as the Gundam Exia and a few guys wearing Tekkadan uniforms.
The legendary Gundam seiyuu even took a video of how good the snowboarding cosplayers were.
