The HBs in the video are the "classic" Hell Bents - 09/10 edition. 122 at the waist. The ones that are 132 at the waist are the new 10/11 green/pink/yellow serial murderer demon clown ones. You kind of can't mistake them for much else out there. They really, really stand out on the snow.
If you look at a pair closely, they are arguably some of the best, and creepiest, topsheets ever. Lots of detail. The subtle integration of clear topsheet sections is way, way cool (the new Obsethed has similar clear sections that work the core into the aurora image).
