Does the ATK V-Crest really have a 3.5mm shorter heel than the regular ATK Crest? Is that because the V-Crest uses a heelpiece more similar to the original Crest and the new Crest has a more robust brake which increases the height?

I am a big fan of the original Skorpius and tried these on. I like that the Skorpius has relatively generous toe room (length and width) compared to other lightweight boots. The Kilo is slightly tighter and would require punching for me, not sure how much room you would be able to get. I can verify the weights Skimo Co has posted, the Kilo is around 80g lighter in 275. The cuff on the Kilo is noticeably shorter and softer, and the walk mode is noticeably better, it is remarkably frictionless. As a compariso...

These pants work very well for their intended purpose, which for me is touring on cold days. I don't think I run particularly warm or cold, but for me these pants are best in temps between +5F and +20F with no baselayer. I will wear a thinner pant on warmer days, and they are not the best choice for most spring tours unless you run cold. I normally don't like touring with gaiters but I like the built-in gaiters on these for deep trailbreaking.

+1 to what Carlos said, except for me they are comfortable with no baselayer in temps between 15F and 40F. The material is surprisingly water resistant and they hold up in deep bootpacks, at least in Utah snow. These pants are basically the same as the discontinued Avenger, for those who are looking for a replacement. The only real difference I've noticed is a slightly improved waistband. I will say if you use a beefier boot, they will work but it could be annoying to peel the cuff on and off at every tra...
