Ericwrote a review of Assos LL.haBu_s5 Cycling Bib Tights on November 8, 2013
Familiarity: I've put it through the wringer
These tights are probably the best cycling kit investment I have ever made. These are so good, I even plunked down on a second pair! The fit is sublime, like a second skin. No bunching, no slipping around. The pad is on thicker side, but very comfortable and stays in place well. For proper fit the bibs should feel quite snug when standing, but once on the bike they are perfection. I am 6', 170 lbs, 33" waist, 38' chest and size L is perfect. I have used them in temps from 4 - 12 Celsius (39 - 53 F), both wet and dry. If it is super windy and cold these are probably not quite enough, I prefer to have something with windproof panels on the front when the temps get down near freezing (I have older LL Winter tights sans chamois for those days).
Seriously, if you are considering buying these tights just pull the trigger - you won't regret the decision but I won't be held responsible if you end up buying 2 pair.
