“Compression” tights?

I believe the idea is about providing support in various places. From what I've read, compression shorts/tights provide support [especially to the quads and hamstrings] which a runner would benefit from when s/he starts to fatigue. Think of them as structural tights – haha! I have no idea if the technology works, but it's been around for a while. Depending on the model, some compression garments are definitely tough to put on b/c they have to be tight in order to be effective. For things like running, I'd consider them, for other things, I'd probably go with something else. I have some semi-compressive shorts and I have to say they're very comfortable and keep my quad/hams warm. Made by Salomon.

Marketing spin
Dangerous spin too.

Yeah, it sounds like it is.

I will try out the golite tights and if they are "compressing" instead of just fitting next to skin, I will return them.

One balanced view on the topic:

The Physiology Behind Compression Clothes

they say the fit is "compression" ie lots of lycra, I'm sure they fit like just about any other running tight-"tight"

they look very similar to my speedwork tights (patagonia calls the fit "formfitting"), about the same weight as well

not sure how warm of "tights" your looking for, but for really cold weather (anything below 20 or lots of wind) I've gone to OR's Centrifuge tights, clearly warmer and more wind resistant than normal running tights- the speedworks normally get the call for 20+ weather

skin-tight underwear.

Tight clothing CAN do things for you.
For example, the lifting shirts that some weightlifters wear can increase their bench press by ~25lbs.

The average "compression tights" or "compression shorts", are just light wt underwear/tights, and arent all that tight.
