Helios Pants
They're fantastic - super soft and comfortable!

It’s like having a heating blanket on from the waist down
So far the only use I’ve gotten is walks around my neighborhood and to the park to play fetch with the dog. They have served their purpose which was to keep me warm during low cardio activity. I picked these up to keep warm when I stop and take a break during long fat bike/hiking outings. The weather has not dropped below 15f, but I do not think I’ll have any issues staying warm below that. I do wish the length was a tad longer, and the waist band had more of a tightening system other than button snaps.

Fantastic Pants
Yet to leave for my whistler trip yet but I can already tell these are going to keep me more than toasty. I love the full length zip too, I feel as if they fit true to size more so than a bit small but just my opinion.
need a fly
This is a good pant but needs a fly. If you are already wearing a harness but need to throw on these puffy pants due to a weather change, it would be great to be able to unzip a fly to stick the belay loop through. You cannot do that with this pant.
GREAT PANTS
Fantastically warm yet light. Good fit, true to size. I am 5' 7" 140 lbs female, typically wear size 8 pants
