Familiarity: I've used it several times
Fit: True to size
So yes, this are warm. 25 degrees F, and worn with a pair of jeans works well if you're moving a bit.
The one set back: these do not eliminate odor, they just trap it in. Without going into details, that is a set back if you've been real active all day.
After not even a couple weeks of wearing them, the stitching became undone along the waist and side leg seam.
I'd say it is true to size, but others are right, some quick adjusting is needed to get them fitted on properly. I wouldn't recommend these, unfortunately.
