Summary:
These tights are a huge disappointment. I currently live in SE Virginia and the winters are not what you'd call brutal, though we often get runs of days in the upper 20s and low 30s in Jan/Feb. I bought the Assos tights for days such as these because my regular lycra tights with an undergarment just didn't cut it. I soon found that these Airblock 851 tights did not live up to their reputation (or their price!). At about 40 degrees my quads and glutes became wooden with cold after about an hour in the saddle. By the time I got home I could barely lift my leg over the bike to dismount. I didn't shake the cold until I'd taken a hot shower and even then I could feel the skin was still chilled to the touch. I have no idea what these would be like in REALLY cold weather, but I shudder to think about it. I think they require a base layer to be effective, but that seems to defeat the purpose. Then we're just talking about an insulating air layer.

Strengths:
Rugged construction, easy on-off.

Weaknesses:
Not truly insulating by themselves. Sizing is misleading. I bought the large and should have gone up one size (my measurements are 6 feet tall, 165 lbs, large quads).

PRICE! I paid $220. That's twice what they're worth.

Bike Setup:
whatever

Summary:
These pad-less tights are the best I've used to date, the airblock panels are extremely effective. I've been comfortable in conditions as cool as 20 F, give or take a couple degrees, which as I recall is somewhat better than the manufacturer's claims. But, as I got these in November, I don't know how far above 55 or so they'd be usable. Spring will tell. Overall, an excellent and much needed addition to my collection, as I commute throughout the entire winter.

Strengths:
Airblock panels very effective
Comfy- stirrups good vs. wind, straps don't dig in to shoulders, etc.

Weaknesses:
Mild pilling after 15-20 rides, not sure
if this will become a problem.
Like all Assos products, prohibitively expensive(I know it co$t$ a lot to manufacture in Switzerland, but please...) - about $180 list price

Favorite Ride:

Bike Setup:
2 wheels, 2 metallic triangles, a dash of rubber, simulated leather and hodge- podge of composite and forged gadgets.

Summary:
Excellent fabric, outstanding construction, great style, unbeatable performance.

Strengths:
Comfort, warmth, function. XC skied in 5 degree F temps, kept me warm, wind protection and provides freedom of movement. No pad on this tight for versatility.

Weaknesses:
Expensive but expect it to last a long time.

Summary:
I use these tights primarily for road use and have worn them when necessary since the beginning of January. Temperature at the time of my rides ranged from 20 F to 50 F. These bib tights are surprisingly comfortable within this wide range of temperature. Since there are large windstop panels strategicely placed in the knee and theigh areas windy days are not a problem. The areas without windstop material have a very soft microfleece lining that is very comfortable. I wear these tights in conjunction with the Assos Airblock Prosline Jacket and Airblock Prosline shoe covers. This combination should get most people through all but the coldest winter climates with proper base layering.

Strengths:
Quality of materials
Attention to detail
Assos style
Lots of colors to choose from
Fit (although be sure to try on first because of Euro sizing)
Comfort in wide range of temperatures

Weaknesses:
The zipper on the Airblock jacket rubs against the tights and showed wear. I remedyed this by placing a piece of electric tape over the lower piece of the zipper and the wear has stopped.
